Enhanced expression of the recombinant lethal factor of bacillus anthracis by fed-batch culture

Gupta, Pankaj; Sahai, Vikram; Bhatnagar, Rakesh (2001)

High cell density cultivation has been one of the most effective ways to increase cell as well as the product yields. The structural gene for the 90-kDa lethal factor (LF) isolated from Bacillus anthracis was expressed as ...
Optimization of xylanase production by melanocarpus albomyces IIS68 in solid state fermentation using response surface methodology

Narang, Someet; Sahai, Vikram; Bisaria, Virendra S (2001)

Xylanase production by the thermophilic fungus, Melanocarpus albomyces IIS68, during solid state fermentation of wheat straw was studied and the effects of various variables were observed. Using the response surface ...
Statistical media optimization and alkaline protease production from bacillus mojavensis in a bioreactor

Beg, Qasim Khalil; Sahai, Vikram; Gupta, Rani (2003)

Alkaline protease production in Bacillus mojavensis was improved up to 4.2-fold in a 14 l bioreactor during validation of a predicted statistical model. The final enzyme yield in the bioreactor was 2389 U m1 obtained within ...
