Cellulase shows great interest in the field of organic acids, and biotechnology industries. Cellulase-producing thermophilic bacteria was isolated from West Coast hot spring (Rajapur, Ratnagiri District Maharashtra (Lat. 16°38′42″N; long. 73°31′53″E) identified as Bacillus licheniformis. Out seven variables cellulase production medium, four such carboxy methyl cellulose (CMC), calcium chloride, Tween-20, temperature were screened through Plackett–Burman design further optimized response...

The gut wastes of Sardinella longiceps were used as substrate for protease production. waste has 61.6% proteins, 21.8% lipids, 8.5% carbohydrates on dry weight basis and trace elements. significant factors fermentation screened by Plackett-Burman design. A activity 68.56 U/ml was predicted at 46.31 °C, incubation time 71.11 h, inoculum 4.86% (v/v) concentration 2.66% (w/v), using response surface methodology. However, the validation experiment showed 73.52 activity. artificial neural network...

In the present study, eleven cellulose degrading bacterial strains were isolated from water and soil samples of hot springs in Chumathang village, Leh Ladakh region, India. The identified as Bacillus subtilis, aryabhattai, stratosphericus, altitudinis Brevibacterium frigoritolerans by biochemical molecular approaches. All evaluated for total cellulase, endoglucanase, exoglucanase, β-glucosidase enzyme activities. On basis overall individual activities, three selected to develop consortium...

Abstract Bioethanol is considered to be a possible substitute for non‐renewable fossil fuels. Biofuels, including bioethanol, are gradually replacing coal and oil energy production. It expected that, by 2040, fuels’ contribution the world's demands will only 25% with remaining made up biofuels. One of major factors affecting ethanol production cost raw materials, which can substantially reduced utilizing industrial or agricultural lignocellulosic wastes. Using waste paper as feedstock...
