The objective of this study was to investigate the effects of partially replacing fish meal with FMBH on the growth, digestive enzyme activity, and antioxidant capacity of allogynogenetic crucian carp. Fermented mushroom bran hydrolysate (FMBH) was prepared by enzymatic hydrolysis after the solid fermentation of mushroom bran (MB) inoculated with Ganodermalucidum and Saccharomyces cerevisiae. N...

Penicilliurn expamum grown in a medium with rice husk as a carbon source produced an extracellular protease. The protease enzyme was isolated from culture broth by fractionation with acetone and column chromatography on Sephadex G- 100 and DEAE A-50. The protease enzyme was purified about 17.47 fold, with a recovery of 14%. The purified protease was homogenous on SDS polyacrylarnide disc ge...

Avian frugivores have been somewhat poorly studied with regards to the effects that different fruit sugar types and concentrations have on their digestive efficiencies. Therefore, two relatively large South African frugivores, the Knysna turaco (Tauraco corythaix) and the purple-crested turaco (Gallirex porphyreolophus), were fed artificial fruit that contained equicaloric and equimolar concent...

conclusions in this study, we isolated b. licheniformis producing an organic solvent-stable protease from oil-contaminated soil. the protease was stable and active in various organic solvents. by purification, the protease could be used as a biocatalyst for organic solvent-based enzymatic synthesis. results according to 16srdna sequencing, strain isa9 was identified as a new strain of bacillus ...

Human immunodeficiency virus type 1 (HIV-1) expresses its structural and functional proteins within Gag-Pol precursor polyproteins. Specific proteolytic processing of the precursors by the viral protease is critical for the maturation and infectivity of viral particles. To observe the influence of autoprocessing on the activation of recombinant HIV-1 protease, we constructed different HIV-1 pro...

dacarbazine (dtic) is a synthetic chemical antitumor agent which is used to treat malignant melanoma and hodgkin’s disease. dtic is a prodrug which is converted to an active form undergoing demethylation by liver enzymes. the active form prevents the progress of disease via alkylation of dna strand. in the structure of this drug, the imidazole ring, a triazen chain and carboxamide group exist. ...
