摘 要：The ever increasing energy demands of modern civilization and rapidly dwindling fossil fuels point towards a renewable substitute like ***,higher costs associated with biofuel productions is the major bottleneck for its *** present study demonstrates the use of a statistical approach called response surface methodology(RSM)to investigate the optimum parameters for maximum production of cellulase by Bacillus tequilensis *** Plackett-Bur-man design(PB)of the RSM analysis indicated grass straw(GS)concentration,pH,FeSO4,inoculum,MgSO4,incubation period and NH4Cl as significant variables that influence the cellulase ***,to propose the best medium for the maximum production of cellulase by *** G9,the most influential parameters,namely concentrations of GS as substrate,FeSO4,pH,inoculum size,*** fine-tuned by central composite design(CCD)involving four factors and five *** CCD analysis demonstrated 8%substrate concentration,1.5%of inoculum along with 10 ppm FeSO4 and a pH of 5.5 in media as optimum conditions for highest enzyme *** field emission scanning electron microscopic analysis of the treated GS showed structural alterations depicting significant deconstruction caused by *** *** yield of the partially purified cellulase proteins were found to be 21%revealing molecular mass between 30 and 97 *** enhanced cellulase production by *** G9 demonstrated in our study brands its applications in many industrial processes like biorefinery,biofuels,etc.
