Researchers genetically engineer micro-organisms into tiny factories

ys to modify both the P450 monooxygenase enzymes and the host cell, thereby improving their yield of flavonoids.

Microbial biosynthesis methods also are making it easier to create analogs of existing drugs, as well as new molecules for a broad range of therapeutics.

The UB researchers are particularly interested in developing novel molecules that can be used to treat chronic diseases, such as type II diabetes and obesity.

They also are using the methods to produce specialty compounds, such as natural pigments, that could replace chemical dyes in food.

Koffas goal is to employ these microbial synthesis methods for a wide variety of applications.

Flavonoids, which are of interest to pharmaceutical companies because of their antioxidant and anti-carcinogenic properties, are difficult to produce using currently available methods.

Microbial synthesis strategies also are being adapted by the UB researchers for the biosynthesis of other commercially significant classes of compounds, including vitamins, anti-cancer drugs, anti-parasitic drugs, dyes and food supplements.

The UB group is working on boosting yields further and hopes to achieve pilot scale production of flavonoids by the end of this year.
