This study was carried out to evaluate the effects of different levels of fermented daphnia (Daphnia magna) as a partial protein source of rainbow trout (Oncorhynchus mykiss) alevins’ diet and its effect on growth; nutrition and feed efficiency for 8 weeks. Rainbow trout alevins with an initial body weight of 0.583 ± 0.197g (Mean ± SD) after acclimating to study condition were fed in 5 treatmen...
Biodegradation of Model Azo Dye Methyl Red and other Textile Dyes by Isolate Bacillus circulans NPP1
The three-dimensional structure of the Bacillus stearothermophilus "maltogenic" alpha-amylase, Novamyl, has been determined by X-ray crystallography at a resolution of 1.7 A. Unlike conventional alpha-amylases from glycoside hydrolase family 13, Novamyl exhibits the five-domain structure more usually associated with cyclodextrin glycosyltransferase. Complexes of the enzyme with both maltose and...
Bacterial chitinases are useful in the biocontrol of agriculturally important pests and fungal pathogens. However, the utility of naturally occurring bacterial chitinases is often limited by their low enzyme activity. In this study, we constructed mutants of a Bacillus thuringiensis chitinase with enhanced activity based on homology modeling, molecular docking, and the site-directed mutagenesis...
