Early in the history of the commercial production of penicillin, various related antibiotics, called penicillins F, K and X, were identified among the fermentation products along with what proved to ...

Penicillin G acylase (PGA) remains a linchpin in the industrial synthesis of β-lactam antibiotics, with Escherichia coli serving as the primary host for its large‐scale production. The enzyme ...

The natural resistance of 15 enterotoxic and 5 non-enterotoxic strains of staphylococci to penicillin was determined. The enterotoxic strains were found to have a wide range of resistance to ...

A new technique gives biofuel-producing microbes the upper hand against unwanted invaders. The development could reduce the cost and environmental impact of producing liquid biofuels and biochemicals ...

Figure 1: Four different strategies for 7-ADCA production. Figure 5: Genetic map of the plasmid pALC88 used to introduce ring expansion activity (DAOCS) into A. chrysogenum ΔcefEF. Fermentation ...

To thwart interfering microbes, scientists created biofuel-making bacteria and yeasts that get essential nutrients from manmade sources. Scientists haven’t ironed out all the kinks of making biofuels ...
