The `Plastractor` is a device which shall extract microplastics from fluids easily via magnets. Therefore the bacterium Rhodospirillum rubrum `magneticum` was obtained. It is genetically modified to build magnetosomes; small magnetic and vesicle-like particles, with plastic binding peptides on its membrane. For modification we use E. coli BW29427 which transfers the needed plasmid to Rhodospirillum rubrum `magneticum` via conjugation. Two different plastic binding peptides are used, `Tachystatin A2` (TA2) and `liquid chromatography peak I` (LCI), fused with two different fluorescent proteins to enable the detection of the bound particles. Thus the device will be able to extract the plastics that are bound to magnetosomes and detect it by fluorescence.', 'poster_number':'260', 'poster_zone':'Zone 3', 'presentation_day':'Saturday', 'presentation_room':'Ballroom A', 'presentation_time':'11:30 AM', 'medal':'Gold', 'nomination':'Best Environment Project','award':'-','parts_link':'http://parts.igem.org/cgi/partsdb/pgroup.cgi?pgroup=iGEM2019&group=Aachen', 'wiki_link':'https://2019.igem.org/Team:Aachen'}, {'team_name':'Aalto-Helsinki','institution':'Aalto University', 'location':'Finland', 'region':'Europe', 'track':'Manufacturing', 'section':'Overgrad', 'title':'VibXPRESSO - A Vibrio natriegens strain for efficient production and secretion of recombinant proteins','abstract':'Recombinant proteins are widely used in biomedical research and as biopharmaceutical compounds.

We harness the gram-negative bacterium`s generation time of under 10 minutes to rapidly produce large amounts of protein for efficient purification. This is achieved via the twin-arginine translocation (Tat) pathway, that secretes proteins into the bacterium`s periplasm. By environmental modifications we have increased the outer membrane leakiness ofV. natriegens, to direct proteins from the periplasm into the growth medium for easier protein harvest.

However, the analyte binding antibodies in conventional immunoassays are randomly immobilized onto a test surface blocking some binding sites from the analytes. When the concentration of a disease marker as the analyte is below the detection limit or the sensitivity, the signal could be improved by orienting the antibodies. Our objective was to orientate a digoxigenin binding Fab fragment of the antibody by incorporating a p-azido-L-phenylalanine, an unnatural amino acid with click chemistry properties. As a control, we used a chemically treated Fab including azide in random locations.

Using this chitinase, M. oryzae is able to avoid triggering the rice`s defense mechanism that would inhibit the spread of the fungal infection. However, by preemptively exposing the rice plant to chitin it is possible to trigger the rice`s defense mechanisms before M. oryzae can suppress detection methods.

Sharks` liver oil is the richest natural origin of squalene. However, this origin is limited because of epidemic marine pollution, overfishing of sharks and the international concern on shark protection.The goal of this research is to produce squalene using E.coli, the most common microbial factory. To achieve this, we need to introduce exogenous squalene synthase (SQS) into E.coli.Firstly, we compared the yield using SQSs from different species. To facilitate this, CrtN, turning colorless squalene into yellow ß-carotene, is introduced. Secondly, an exogenous MVA pathway is introduced and a more effective MEP pathway is developed via overexpression of key regulatory enzymes. Both pathways produce the precursor of squalene in E.coli and eventually improve the squalene yield.This research provides an alternative to squalene production, bringing positive effects on shark protection.', 'poster_number':'HS 25', 'poster_zone':'HS Zone 1', 'presentation_day':'Friday', 'presentation_room':'Ballroom A', 'presentation_time':'12:00 PM', 'medal':'Bronze', 'nomination':'-','award':'-','parts_link':'http://parts.igem.org/cgi/partsdb/pgroup.cgi?pgroup=iGEM2019&group=SEFLS_Shanghai', 'wiki_link':'https://2019.igem.org/Team:SEFLS_Shanghai'}, {'team_name':'SEU','institution':'Southeast University', 'location':'China', 'region':'Asia', 'track':'Open', 'section':'Undergrad', 'title':'Synthesizing Neurons in Artificial Neural Networks with DNA reactions','abstract':'Artificial intelligence has become a hot topic for years, as it has the potential to provide a general tool for solving different problems.

Overuse of antibiotics has led to the problem of antibiotic resistance, which begs the advent of a different therapeutic approach. Incorporating Escherichia coli into our solution, our team sought to create a chassis that can detect, move towards, and kill MRSA. Our detection system utilizes AgrC and AgrA system from S. aureus to detect AIP released from MRSA and activate the P2 promoter. The P2 promoter then initiates motility and the killing mechanism. Movement is controlled by the motility gene, cheZ, which initiates movement towards AIP. Killing is accomplished by genes gakA, gakB, and gakC from Lactococcus garvieae with a secretion signal attached, which produces the bacteriocin garvicin KS for extracellular secretion.', 'poster_number':'157', 'poster_zone':'Zone 2', 'presentation_day':'Saturday', 'presentation_room':'306', 'presentation_time':'3:30 PM', 'medal':'Silver', 'nomination':'-','award':'-','parts_link':'http://parts.igem.org/cgi/partsdb/pgroup.cgi?pgroup=iGEM2019&group=UNebraska-Lincoln', 'wiki_link':'https://2019.igem.org/Team:UNebraska-Lincoln'}, {'team_name':'UniGE-Geneva','institution':'University of Geneva', 'location':'Switzerland', 'region':'Europe', 'track':'New Application', 'section':'Overgrad', 'title':'Fluosphera','abstract':'The replacement of animal testing by alternative in vitro methods is encouraged by the World Health Organization and the US Food and Drug Administration.
