Optimized Production of Xylanase by and Ultrasound Impact on Enzyme Kinetics for the Production of Monomeric Sugars From Pretreated Corn Cobs.

Corn cob is an abundant organic source with significant potential in sustainable energy development. For the effective conversion of the feedstocks to valued commodities, effective biocatalysts are highly desired. The present study aims at optimizing the critical parameters required for xylanase production by isolated from rotten wood sample using the orthogonal array layout of L25 (56).

Improved physicochemical pretreatment and enzymatic hydrolysis of rice straw for bioethanol production by yeast fermentation.

Lignocellulosic biomass such as agricultural and forest residues are considered as an alternative, inexpensive, renewable, and abundant source for fuel ethanol production. In the present study, three different pretreatment methods for rice straw were carried out to investigate the maximum lignin removal for subsequent bioethanol fermentation. The chemical pretreatments of rice straw were optimized under different pretreatment severity conditions in the range of 1.

Plausible exploitation of Jatropha de-oiled seed cake for lipase and phytase production and simultaneous detoxification by Candida parapsilosis isolated from poultry garbage.

Jatropha de-oiled seed cake was explored to utilize as a basic nutrient source for Candida parapsilosis, isolated from poultry garbage and selected based on the production of lipase and phytase enzymes under submerged fermentation. At optimized parameters under solid-state fermentation, lipase and phytase activities were recorded as 1056.66±2.
