For improved biosynthesis of penicillin amidase by E. coli, NCIM 2400, the participation of different carboxylic acids and polyols has been studied in association with the effect of phenylacetic acid. A modified defined medium has been devised for this purpose.

โฆ Synopsis
Different operational mode of bioreactors influence the biosynthesis of the enzyme and related products as well as the growth of industrial microorganisms. This communication deals with the effect of mode of operation of various bioreactors with different geometric configurations, viz., batch (includes commercially available batch stirred tank, and custom-designed cylindrical and tapered reactors), batch-fed, continuous flow stirred tank reactors on the biosynthesis of penicillin amidase in Escherichia coil Experimental findings show that the biosynthesis of penicillin amidase in E. coli show a little variation among batch reactor modes and significant variation on the continuous mode of operation. Further analysis show that the different reactor modes also influence periplasmic localization of the enzyme in the cell.

Selection experiments between a lac+wild type and a lac-mutant of Escherichia co/i were conducted using a serial transfer procedure at two levels of total sugar concentration, i.e., 0.750 g/l and 1.0 g/l, The relative frequencies of both genotypes were assayed every 48 hours, at the time of transfer
The stabilisation of Escherichia coli penicillin G acylase (PGA) by dextran polymers (of molecular weight 11.5, 37.7 and 71 kDa) was studied.
