主 题:Agrowastes Cellulose RAST Endoglucanase Paenibacillus lautus
摘 要:In the present study,Paenibacillus lautus strain BHU3 isolated from landfill soil was evaluated for the presence of potential endoglucanases which are the first candidate of cellulase enzyme system to act on ***-silico analysis revealed high potential thermostable endoglucanases which can efficiently interact with *** most potent and thermostable endoglucanase(locus tag ***30_18280)belonged to glycosyl family-5 and had interaction energy of−12.981 kcal/mol for the best docked cluster containing three out of ten docking conformations,and Tm value of 73.3℃.MD simulation of 100 ns proved highly stable binding interactions of CPZ30_18280 endoglucanase with cellulose with root mean square deviation(RMSD)values ranging from 0.15 to 0.30 *** interactions with characteristic active site residues(tyrosine,tryptophan and aspartate)of glycosyl family-5 endoglucanases were ***,to enhance the production of endoglucanases,the fermentation conditions were optimized employing approaches like one factor at a time(OFAT)and response surface methodology(RSM).Maximum activity of endoglucanase was determined at 60℃.The optimized condi-tions for enhanced production of endoglucanase(10.15 U/mL)were pH 6.63,yeast extract conc.3.44 g/L,wheat bran 3.59%,and inoculum size 2.65%.Hence,*** strain BHU3 has enormous potential to synthesize highly efficient thermostable endoglucanases under optimized regime using ***,it could find immense industrial applications including large scale cellulose conversion to bioethanol.
