For the visually impaired

Science isn't reserved for anyone, and we have made sure that our page embraces everyone by following a few key aspects of accessibility, like for example providing every image on this page with an 'alt'-text, which means that a screen reader program will make sure that everyone can enjoy our graphics and get the exact information that they convey. We also made sure to translate the 'alt'-text alongside all the other text on the front page and the description.



If you are interested in making your own page more accessible, then click below and read our easy guide to include visually impaired, color blind and people who are hard of hearing.

Library of Engineered Aspergillus Promoters

A World of Biotechnology

Many everyday products are produced using microorganisms such as fungi. The production of these products is regulated by small DNA sequences called promoters. These are necessary tools to optimize the yield of the desired product and minimize the yield of others.

Promoters

These promoters work as regulators for gene expression. Think of it as a gear in a car. Some gears make the car go fast, and others lower the speed. This is done by controlling the transcription of a gene, as it determines the strength at which the RNA polymerase can bind.

Our Library

Therefore we are creating a library of synthetic fungal promoters that are: predictable, robust, and scalable. These were designed using special software based on sequence conservation. In the design we have included feedback from relevant companies and scientists, meaning that the promoters are useful in both industry and academia.

Did you know?

The total annual revenue from enzymes produced by Aspergillus spp. is 480 mio USD per year [3].
