+ | <li> Mount the impellers at the correct height. </li> | ||
+ | <li> Attach the sparger and baffles, and secure them with the bolt at the top of the bioreactor. </li> | ||
+ | <li> Mount the condenser, preferably as close to the control tower as possible. </li> | ||
+ | <li> The mouth of the condenser is loosely packed with a bit of glass wool, and the condenser is closed off. </li> | ||
+ | <li> The temperature and sampling pipe is mounted, and the sampling tubing is attached and sealed off with both a butterfly clamp and a regular clamp. </li> | ||
+ | <li> The inoculation port (with membrane) is assembled and mounted. </li> | ||
+ | <li> The 4-way connector is attached to the bioreactor, and the un-needed connections are closed off with a knotted piece of tubing. </li> | ||
+ | <li> Marprene tube is attached to the air inlet, and an air filter is attached to the tubing in the right direction. </li> | ||
+ | <li> Assemble the bioreactor, using a bit of lab grease on the rubber gaskets. </li> | ||
+ | <li> Connect the empty 250 mL Blue Cap bottles (acid/base) to the 4-way connector, with tubing appropriate for the control tower pumps. </li> | ||
+ | <li> Clamp tubing between the bioreactor and bottles, as close to the reactor as possible. Also, attach a clamp the tube leading to the air filter. </li> | ||
+ | <li> Secure all tubing with white strips. </li> | ||
+ | <li> Fill the reactor with 1 L of minimal medium (<a href="#Minimal-media" >see media recipe</a>). </li> | ||
+ | <li> Calibrate the pH-electrode, and pressure test the reactor. </li> | ||
+ | <li> Cover all open ends and filters with tin foil to protect them during autoclaving. </li> | ||
+ | <li> Check all clamps prior to autoclavation, and loosen the main screw to prevent overpressure. </li> | ||
+ | <li> Autoclave the bioreactor. </li> | ||
+ | <li> After autoclavation, close the loose fitting and mount the air supply. Set the flow rate on the DCU to 0.75 vvm, and remove all clamps except for on the sampling tubing. </li> | ||
+ | <li> Once the medium has cooled down, connect the condenser tubing, the temperature jacket tubing, pH-electrode, DO-electrode, and the stirrer. </li> | ||
+ | <li> Set the stirrer to 800 rpm and check the accuracy of the pH-electrode. Calibrate if needed. </li> | ||
+ | <li> Mount the tubing for the acid and base on their respective pumps, run the acid/base through the tubing and switch to “auto”. </li> | ||
+ | <li> Calculate the inoculum volume to a final concentration of 10<sup>6</sup> spores/mL, and inoculate the bioreactors with the previously prepared spore suspensions (<a href="#Sporesuspensions" >See Here</a>). </li> | ||
+ | <li> Add 50 µL of Sigma 204 Antifoam to the reactor. </li> | ||
+ | <li> Due to species limitations, 0.7 g of arginine was added to the media of the positive control. </li> | ||
+ | <li> Set the timer to zero at the DCU, and start the batch fermentation at the desired process values. </li> | ||

Protocols
Lab friendly downloads available for all protocols
This protocol is adapted from a protocol used by DTU Bioengineering.
Materials
- Fungal plates (either streaked or 3-point)
- Drigalski spatula
- 500 mL shake flasks
- Counting chamber
- Solutions (APB, ATP, PCT, Milli-Q, TM)
- 30 °C incubator with shaking
- Sterile tea spoon
- Mira cloth in funnel (sterile)
- Glucanex
- Magnet stirrer
- Magnets
- 50 mL sterile falcon tubes
- 0.45 µm filters
- 50 mL syringe
- Centrifuge for falcon tubes
Media
- Aspergillus transformation buffer (ATB)
- Aspergillus protoplastation buffer (APB)
- 500 mL shake flasks
- YPD media
Procedure
Initiation
- Streak spore suspension of host strain on YPD plates supplemented with uridine (for this particular fungus) and let grow for a week (there should be black spores!)
- All solutions should be sterile.
Day 1 (inoculation)
- Add 95 mL of YPD media supplemented with uridine to a shake flask and transfer 5 mL of the YPD media to a plate with A. niger. Collect conidia and spores from plate by carefully scraping off the conidia using a drigalski (the spores are hydrophobic and would therefore rather just fly around than actually get into suspension so be careful not to make a mess here). This should give a concentration of around 108 spores/100 mL. It is a good idea to make more than one shake flask at a time.
- Incubate shake flasks at 30 °C, 150 RMP for 48 h.
Day 3 (mycelial harvest)
- Place the sterile funnel with a mira cloth in to a sterile blue cap bottle and transfer the contents of the shake flasks to the mira cloth (content should be brown and thick).
- Wash the mycelia using Aspergillus protoplastation buffer (APB) to remove residual glucose from the mycelia (this can inhibit protoplastation). You need to use quite a bit of APB. squeeze out remaining liquid using a sterile spoon. Then, transfer the mycelium to falcon tubes ( ≈2 g per tube => 1 shake flask ≈ 2 falcon tubes).
Protoplastation
- Add glucanex to APB to get a final concentration of 40 mg glucanex per mL APB and dissolve glucanex via gentle magnetic stirring and no heat.
- Sterile filter 20 mL of APB+glucanex to each falcon tube using a 0.45 µm filter and a 50 mL syringe (there is a bit of resistance in the filter but that's ok).
- Shake/incubate enzyme-mycelium mix at 30 °C, 150 rpm for 2-3 h.
- From now on, whenever you pipette anything with the cells in it, cut of the edge of the pipette tip and CAREFULLY(!) pipette the cells. If you don't do this, they break as they don't have a cell wall to keep them stable.
- Evaluate the number and quality of protoplasts in a microscope and discard a batch that is too diluted (i.e. < 105 protoplasts/mL). Approved protoplast solutions are then diluted by pouring APB up to 40 mL. and the tubess are balanced. Dilute Aspergillus transformation buffer (ATB) to 1/2x with sterile Milli-Q water and carefully place 5 mL of this on top of the APB, creating an overlay. Centrifuge samples on rotor settings rotor code Sla-600TC; time: 13 min; Speed: 3000g; Temperatire: 16 °C, Acc: 2, Brake: 2 (NB! due to slow acc and brake, this takes forever!)
- In the interphase between the two liquids, a halo of white slurry consisting of concentrated protoplasts should be observed. If there is cell wall debris mixed in with the protoplasts, that's ok. They can still be used. Withdraw the protoplasts with a pipette and wash them in a new falcon tube. Add ATB up to 40 mL and pellet the protoplasts at 3000g for 13 min (acc. 2, brake 2). Discard supernatant by decanting.
- Count protoplasts in microscope by diluting a small sample 1:100.
- Resuspend protoplasts in 4 mL ATB to obtain concentrated solution.

A quick overview of the two different transformation protocols
Materials
- DNA
- Protoplasts
- Falcon tubes
- PCT
- TM molten agar
- TM plates
- ATB
Procedure
Regular protocol
- Add at MOST 20 µL DNA ( or max 25% of protoplast volume) and 100 µL of protoplasts in a 50 mL falcon tube.
- Incubate in the falcon tube at RT for at least 30 min.
- Add 1mL of PCT.
- Gently mix by gently swirling the tube in a circular motion – careful they are fragile. Do not vortex or pipette mix.
- Incubate for 5 min at RT.
- Add 3 mL of ATB.
- Add 12 mL of molten (40-45 °C) TM agar.
- Immediately pour mixture directly onto TM plates, and swirl to spread mixture evenly.
- Let the plates settle for a few minutes and incubate at 37 °C for 4 days.
Quick protocol
- Add at MOST 25 µL (1500-5000 ng) DNA ( or max 25% of protoplast volume) and 100 µL of protoplasts in a 2 mL Eppendorf tube. 1 µL (100 ng) pac6 as positive control.
- Add 150 μL PCT with large-nozzle pipette tip.
- Gently mix by swirling – careful the protoplasts are fragile.
- Incubate 10-30 min at room temperature.
- Add 250 μL ATB.
- Distribute transformation mix on osmotic-stabilized selective media and let the agar absorb the mix before incubating

Protocol for producing a glycerol stock of E. coli adapted by Jacob Mejlsted from Addgene's protocol.
Materials
Consumables
- 2 mL screw top tube or cryovial
Chemicals
- 50% glycerol
- Cell culture
Procedure
Making the stock
- After having cultivated a culture overnight, add 500 µL culture to 500 µL 50% glycerol in the selected tube
- The stock can now be frozen at -80 °C
If the stock is repeatedly thawed and frozen, it will reduce the shelf life of the culture
Using the stock
- To recover bacteria, take a innoculation loop, toothpick or pipete tip and scrape a small amount of bacteria off the top.
- Transfer this to a plate or a tube with liquid media for growth.
Normally, media with antibiotics are used. Here Amp and Cam are among the most used.

How to load and clean biolector plate.
Materials
- Biolector
- Minimal media
- P1000 pipette and tips
- P10 pipette and tips
- Spore suspensions
- Biolector plate
- Lid for the biolector plate
Procedure
- NB! Make sure to do all work in a clean LAF-bench!
- Clean plate with ethanol and a cotton swab and leave to dry
- Clean additionally using UV for >30 min.
- Add 1500 µl minimal media (+supplements if necessary) to each well.
- Add spores to the wells to achieve a final concentration of 106 or 107 spores per mL.
- Add a lid for the plate. These are sticky and should be breathable, i.e. the white, kind of fabric-y lids
- Run Biolector for 36 hours
- After run, fill all wells with ethanol and clean using "soft" things such as a pipette tip to get to the corners and a cue tip to clean the sides. Repeat this process until the plate is clean.

- Connect the empty 250 mL Blue Cap bottles (acid/base) to the 4-way connector, with tubing appropriate for the control tower pumps.
- Clamp tubing between the bioreactor and bottles, as close to the reactor as possible. Also, attach a clamp the tube leading to the air filter.
- Secure all tubing with white strips.
- Fill the reactor with 1 L of minimal medium (see media recipe).
- Calibrate the pH-electrode, and pressure test the reactor.
- Cover all open ends and filters with tin foil to protect them during autoclaving.
- Check all clamps prior to autoclavation, and loosen the main screw to prevent overpressure.
- Autoclave the bioreactor.
- After autoclavation, close the loose fitting and mount the air supply. Set the flow rate on the DCU to 0.75 vvm, and remove all clamps except for on the sampling tubing.
- Once the medium has cooled down, connect the condenser tubing, the temperature jacket tubing, pH-electrode, DO-electrode, and the stirrer.
- Set the stirrer to 800 rpm and check the accuracy of the pH-electrode. Calibrate if needed.
- Mount the tubing for the acid and base on their respective pumps, run the acid/base through the tubing and switch to “auto”.
- Calculate the inoculum volume to a final concentration of 106 spores/mL, and inoculate the bioreactors with the previously prepared spore suspensions (See Here).
- Add 50 µL of Sigma 204 Antifoam to the reactor.
- Due to species limitations, 0.7 g of arginine was added to the media of the positive control.
- Set the timer to zero at the DCU, and start the batch fermentation at the desired process values.

By David Faurdal, adapted in part from NEB's one-taq protocol.
The purpose of this protocol is to confirm correct insertion of fragments after assemblies, such as 3A, Gibson, or Golden Gate. As the fragments run on the gel won't be used for cloning purposes, there is no reason to use high-fidelity polymerases on this, just use one-taq.
Materials
- Transformants from whatever assembly method you fashion
- Eppendorf tubes
- Sterile toothpicks/inoculation lops/pipette tips for transferring colonies
- Sterile water
- LB media with apropriate antibiotics
Procedure
Preparing the template DNA from the transformants:
- Pick a number of transformants, typically 3-10, from each plate of interest and mark them on the back of the plate.
- Set up 2 eppendorf tubes for each colony and mark them accordingly:
- Fill the first one (1) with 15 µL MQ water.
- The other one (2) remains empty for now.
- Transfer each colony to the eppendorf containing 15 µL water using a sterile toothpick, inoculation loop or autoclaved pipette tip.
- Transfer 5 µL of the water from (1) to the empty (2) tube. This tube (2) is now for safekeeping in case the colony PCR shows that the transformant in question contains the correct insertion.
- Boil the (1) tubes for 10 minutes at 98 °C. Prepare the PCR mastermix, while the colonies are boiling.
Setting up the PCR itself:
- Set up a 25 µL reaction for each colony to be screened, as per NEB'S one-taq PCR protocol (see the protocol for troubleshooting).
Component | 25 µL reaction |
---|---|
5x OneTaq Standard Reaction Buffer | 5 µL |
10 mM dNTP | 0,5 µL |
10 µM Forward Primer | 0,5 µL |
10 µM Reverse Primer | 0,5 µL |
OneTaq DNA Polymerase | 0.125 µL |
Template | 1 µL from the (1) tube |
Nuclease-Free Water | up to 25 µL |
- Run the PCR in the thermocycler (use this website to calculate temperatures used based upon the primers and polymerase used).
- Run the products on a gel to check for correct insertion.
- Prepare an O/N culture from the (2) tubes that have the correct insertions by adding 1 mL LB media to the tube, mixing it and transfer a W-tube containing 4 mL LB media.

- Measure the OD 600 of each starterculture, and inoculate the shakeflask with a volume so the final OD 600 value in the shakeflask culture becomes 0.01
- Grow the shakeflask culture at 37 °C with shaking. Measure OD values of the sample every 20 minutes once the OD 600 value is above 0.2.
- When OD 600 is between 0.3 and 0.4, put the cultures into an ice bath immediately, and swirl the shake flash around in the cold water to cool culture. Chill the culture in the ice water for 20-30 minutes, occasionally swirling the cultures.
- FROM THIS STAGE ON, KEEP CELLS AT ICE/4 °C AT ALL TIMES
- For each shakeflask culture, pour the culture into 3 x 50 mL frosted falcon tubes from the freezer.
- Keep the tubes on ice
- Centrifuge falcon tubes at 3000 x g for 15 min at 4 °C (Spin #1 of 4)
- Discard supernatant, and resuspend cells in 15 mL icecold 0.1 M MgCl2
- Keep tubes with cells on ice

Materials
Materials
- Resuspended DNA to be transformed
- 10 pg/µL Positive transformation control DNA (e.g. pSB1C3 w/ BBa_J04450, RFP on high-copy chloramphenicol resistant plasmid. Located in the Competent Cell Test Kit.)
- Competent Cells (50 µL per sample)
- 1.5 mL Microtubes
- SOC Media (950 µL per sample)
- Petri plates w/ LB agar and antibiotic (2 per sample)
Equipment
- Floating Foam Tube Rack
- Ice & ice bucket
- Lab Timer
- 42 °C water bath
- 37 °C incubator
- Sterile spreader or glass beads
- Microcentrifuge
Procedure
Method: Day 1
- Resuspend DNA in selected wells in the Distribution Kit with 10 µL dH2O. Pipet up and down several times, let sit for a few minutes. Resuspension will be red from cresol red dye.
- Label 1.5 mL tubes with part name or well location. Fill lab ice bucket with ice, and pre-chill 1.5 mL tubes (one tube for each transformation, including your control) in a floating foam tube rack.
- Thaw competent cells on ice: This may take 10-15 min for a 260 µL stock. Dispose of unused competent cells. Do not refreeze unused thawed cells, as it will drastically reduce transformation efficiency.
- Pipette 50 µL of competent cells into 1.5 mL tube: 50 µL in a 1.5 mL tube per transformation. Tubes should be labeled, pre-chilled, and in a floating tube rack for support. Keep all tubes on ice. Don’t forget a 1.5 mL tube for your control.
- Pipette 1 µL of resuspended DNA into 1.5 mL tube: Pipette from well into appropriately labeled tube. Gently pipette up and down a few times. Keep all tubes on ice.
- Pipette 1 µL of control DNA into 2 mL tube: Pipette 1 µL of 10 pg/µL control into your control transformation. Gently pipette up and down a few times. Keep all tubes on ice.
- Close 1.5 mL tubes, incubate on ice for 30 min: Tubes may be gently agitated/flicked to mix solution, but return to ice immediately.
- Heat shock tubes at 42 °C for 45 sec: 1.5 mL tubes should be in a floating foam tube rack. Place in water bath to ensure the bottoms of the tubes are submerged. Timing is critical.
- Incubate on ice for 5 min: Return transformation tubes to ice bucket.
- Pipette 950 µL SOC media to each transformation: SOC should be stored at 4 °C, but can be warmed to room temperature before use. Check for contamination.
- Incubate at 37 °C for 1 hours, shaking at 200-300 rpm
- Pipette 100 µL of each transformation onto petri plates. Spread with sterilized spreader or glass beads immediately. This helps ensure that you will be able to pick out a single colony.
- Incubate transformations overnight (14-18 hours) at 37 °C: Incubate the plates upside down (agar side up). If incubated for too long, colonies may overgrow and the antibiotics may start to break down; un-transformed cells will begin to grow.
Method: Day 2
- Pick single colonies: Pick single colonies from transformations: do a colony PCR to verify part size, make glycerol stocks, grow up cell cultures and miniprep.
- Count colonies for control transformation: Count colonies on the 100 μL control plate and calculate your competent cell efficiency. Competent cells should have an efficiency of 1.5x108 to 6x108 CFU/µg DNA.

The following is a quick and easy protocol for creating the spore suspensions used for storage and the inoculation of the shake flask, biolector, and bioreactor cultivations. .
Materials
Materials
- Fully grown fungi plates (with spores)
- Drigalski spatula
- 96% ethanol
- FireBoy or other flame-sterilizing equipment
- Sterile Milli-Q water
- Sterile mira cloth
- Sterile falcon tubes
- P1000 pipette and tips
- Scissors
- Microscope
- Counting chamber
Procedure
Creating the spore suspensions
- Add mira cloth to a falcon tube.
- Pour 2-3 mL of Milli-Q water onto a plate
- Clean and sterilize a drigalski spatula using ethanol and fire.
- Let the drigalski cool off in the water before commencing the scraping. Then, carefully scrape off the spores from the plate. This should be done with the lid still on and VERY careully as the spores are hydrophobic and would much rather just fly around than being suspended into the water.
- When all of the spores have been suspended into the water, transfer the liquid to the mira cloth using a pipette with the tip cut off.
- When this is done, count the spores in the microscope. Usually, a 1000x dilution is necessary.
- The spore suspension can be kept for up to 3 months at 4 °C.
