study of some growth promotion properties of bacterial isolates from animal manures and identification of selected isolatesabstractbackground and objectives: plants growth in agricultural soils are affected by several biological factors. plant growth promoting bacteria can improve growth and yield of agronomic plants through direct and indirect mechanisms. minimizing consequences of using high ...

Nomuraea rileyi (Farlow) Samson is an entomopathogenic fungus capable of producing a variety of enzymes including proteases and chitinases. Protease derived from microorganisms such as fungi, bacteria, and yeast has established wide spread applications in fields such as in the food, detergent and other industries. This study investigates the strategy for partial purification and characterizatio...

Proteolysis plays critical roles in normal and pathologic physiology; these enzymes are intricately involved in cancer progression and spread. Our understanding of protease function has advanced from nonspecific degrading enzymes to a modern appreciation of their diverse roles in posttranslational modification and signaling in a complexmicroenvironment.This newunderstanding has led to next-gene...

In vitro evaluation of enzyme supplementation is used to predict the in vivo response poultry enzymes. This study aims evaluate efficacy techniques predicting supplementation. Different such as pepsin, amylase, and protease assays were efficacy. The results obtained from compared with same showed that can be effectively recommends use for

Granulocyte lysosomal enzymes can potentially participate in cartilage degradation in inflammatory arthritides. However, we have shown that the quantity of several such enzymes in an inflammatory synovial effusion correlates negatively with the degree of radiographic damage of the joint from which the fluid was sampled. In the current work the quantity of the following 5 protease inhibitors was...

A soil screened Bacillus flexus XJU-1 was induced to simultaneously produce alkaline amylase, alkaline lipase and alkaline protease at their optimum levels on a common medium under submerged fermentation. The basal cultivation medium consisted of 0.5% casein, 0.5% starch and 0.5% cottonseed oil as an inducer for protease, amylase, and lipase, respectively. The casein also served as nitrogen sou...

The substrate specificity of the nuclear inclusion protein a (NIa) proteolytic enzymes from two potyviruses, the tobacco etch virus (TEV) and tobacco vein mottling virus (TVMV), was compared using oligopeptide substrates. Mutations were introduced into TEV protease in an effort to identify key determinants of substrate specificity. The specificity of the mutant enzymes was assessed by using pep...

Thermophilic Bacillus sp. GUS1, isolated from  a soil  sample obtained from citrus garden, produced at least three proteases as detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and zymogram analysis. The enzymes were stable in the alkaline pH range (8.0-12.0), with the optimum temperature and pH range of the proteases being 70ºC and 6.0-12.0, respectively. All th...

Bacillus sp. being industrially important organisms produces a wide variety of extra-cellular enzymes including proteases. Bacillus sp. isolated from local marine samples collected from Saudi Arabi...

BACKGROUND Hydrolytic enzymes, such as cellulases and proteases, have various applications, including bioethanol production, extraction of fruit and vegetable juice, detergent formulation, and leather processing. Solid-substrate fermentation has been an emerging method to utilize low-cost agricultural residues for the production of these enzymes. Although the production of carboxy methyl cellul...
