Commercially available enzymes do not contain all the necessary softwood-specific accessory enzymes to obtain high saccharification efficiency. In this work, six saprophytic fungi obtained from Pinus radiata plantation site were screened for the putative softwood-specific accessory enzyme, β-mannanase. A Penicillium sp. was found to produce β-mannanase in both solid (31.6 units/g of dry biomass...

Abstract Background Diosgenin is an isospirostane derivative, which a steroidal sapogenin and the product of acids or enzymes hydrolysis process dioscin protodioscin. Galactomannans are heteropolysaccharides composed D-mannose D-galactose, major sources locust bean, guar, tara fenugreek. Methods Literature survey was accomplished using multiple databases including PubMed, Science Direct, ISI we...

The study designed and constructed a prototype recirculating aquaculture system (RAS) which was used to examine the liver and kidney histology of hybrid catfish (Heterobranchus bidorsalis (♂) X Clarias gariepinus (♀)) fed six practical diets after 12 weeks. Fingerlings of the test fish, mean weight and length of 1.01±0.02g and 4.63±0.34cm were used for the study. In the formulated diets fishmea...
