the date palm fruit stalk borer is one of the most important pests of date palm in the world. biochemical properties of digestive proteases in oryctes elegans prell larvae were investigated in this research and optimal total proteolytic and trypsin activities were obtained at ph 9.0 and 11.0, respectively. activity staining of protease on sds-page showed one isoform. also, zymogram pattern of t...

The antagonistic potential of culture filtrates of a soil isolate of T. viride was evaluated invitro, against three common post-harvest rot pathogens; A. niger, A. flavus, and F. oxysporum. Assay of three extracellular enzymes; chitinase, protease and cellulase, in respective enzyme-induced culture filtrates revealed the presence of enzyme activity. When 10% (v/v) concentration of the various l...

Diospyros capricornuta is an endemic species widely distributed along the coast of Tanzania that used as food condiments and traditional medicine. The chemical compositions leaves, stem-bark, root-bark extracts; their bioactive potentials against Aspergillus flavus parasiticus were investigated. samples D. extracted using Soxhlet apparatus resultant extracts analyzed Gas Chromatography-Mass Spe...

Most evolutionary algorithms concerned with a memory of evolution aim at memorizing and reusing the recipes of past successes (e.g. fruitful operators or fruitful mutation directions). The scheme proposed here follows the opposite track, and memorizes the past failures of evolution (unnt oospring) through a virtual individual termed the virtual loser. The underlying metaphor is that oospring sh...

the protease enzyme breaks down protein into amino acids as its constructors. protease immobilization onto appropriate support materials plays an essential role in various fields of technology including the food and detergent industries. accordingly, improvement of protease immobilization has been highly regarded due to its applications in bio catalysis. alginate and chitosan are natural polysa...
