Optimization of process parameters for cellulase production from Bacillus sp. JS14 in solid substrate fermentation using response surface methodology BABT
Singh,Jagdish; Kaur,Pawandeep.
The aim of this work was to isolate the potent bacterial strains for the production of cellulose enzyme. A total 30 bacterial isolates showed positive results for the cellulase production but highest enzyme activity was shown by isolate JS 14. From the morphological and biochemical reactions, the isolate was identified as Bacillus sp. Cellulase production was studied by this strain using response surface methodology (RSM). A central composite design (CCD) quadratic response surface was applied to explicate the parameters that significantly affected cellulase production in solid substrate fermentation (SSF). The wheat bran concentration and incubation period were significant factors. The process parameters optimized with response surface methodology was...

Partition of glucose oxidase from Aspergillus niger in aqueous two-phase systems based on salt and polyethylene glycol BABT
Singh,Jagdish; Verma,Neelam.
The aim of this work was to study the isolation of glucose oxidase (GOx) from Aspergillus niger in aqueous two phase system consisting of PEG 7500 (150g l-1), potassium phosphate (175 g l-1, K2HPO4 +KH2PO4) and glucose (10 gl-1), the enzyme was partitioned in polymer phase. By sequential extraction GOx (69.2%) was recovered in polymer phase by 11.8 fold purification, giving a yield of 129U mg protein-¹.
