Use of Nonspecific, Glutamic Acid-Free, Media and High Glycerol or High Amylase as Inducing Parameters for Screening Bacillus Isolates Having High Yield of Polyglutamic Acid

Figure 3

Effect of glycerol on PGA yield by Bacillus licheniformis T. glycerol concentration in medium was varied from 0 to 5% (G0–G5) keeping citrate as 2% (C2) in the Bushnell and Hass medium base (pH 7). For solid medium 25 g agar/l was added. Media were inoculated using the same concentration of inoculums. Polymer yield is in g/l.
