Amylase Production

The aim of this work was to optimize the process parameters through the statistical approach for the production of alpha amylase by Bacillus subtilis ZJF-1A5 in submerged fermentation (SMF). The process parameters influencing the enzyme production were identified by using response surface methodology. Among the variables screened, the temperature and time were most significant and showed a positive interaction. The optimum levels were: temperature 35.8 °C, pH 5.03 and time 54h and under these conditions α-amylase yield was up to 191.15 U/mL.

Fermentation Optimization

The production of biomass from Bacillus licheniformsis B1 was investigated in submerged fermentation. Optimization of culture medium was carried out by using response surface methodology (RSM). The B1 biomass production was also significantly affected by dextrose, soya, CaCl2. In addition, while the optimum cultivation parameters were (g/L): 44.026 of dextrose, 34.025 of soya and 3.491 of CaCl2, the prediction of biomass production of B1 was 6.05 x 109 CFU ml-1.
