Quality feed in aquaculture is very important to increase the growth and health of fish. Low efficiency can be overcome by supplementation using catalytic enzymes. One enzymes that stimulate digestion protease red ginger plants. The enzyme plants plays a role breaking peptide bonds place carboxyl groups so peptides are formed from complex compounds into simpler compounds. This study aims determ...

background and objectives: thermophilic bacteria are less studied but important group of microorganisms due to their ability to produce industrial enzymes. materials and methods: in this study, thermophilic bacteria were isolated from hot spring of tarabalo, india. a bacterium that could tolerate high temperatures was characterized by morphology, biochemistry and sequencing of its 16s rrna gene...

The effects of Bacillus subtilis protease, Type VIII (subtilopeptidase A, EC 3.4.4.16), on the lipolytic action of norepinephrine, corticotropin, caifeine, and theophylline on isolated adipose cells were examined. The results indicate that B. subfilis protease, at concentrations suboptimal and optimal for the enhancement of glucose utilization, inhibited, like insulin, the lipolysis mediated by...

Actinomycetes is one of the microorganisms which have ability enzymes hydrolases such as cellulose, amylase, protease, and manannase. Manufacturer hydrolase can be used a candidate probiotic. A probiotic should good resistance in different environmental conditions including pH salinity.  This research conducted to filter candidate’s probiotics from bacteria that tolerance salinity has activity ...

This study was conduction to find a suitable and cheap plant as a source for extracting vegetable protease enzymes and investigate the effect of these enzymes for producing whey protein hydrolysate. The extract prepared from the composite weed cichorium pumilum had a satisfactory protease activity, each ml of this extract prepared from 0.1 gm dried cichorium weed stems.An alkaline and acidic ci...

The large and growing number of protease genes identified in the human genome, more than 560, reflects the complexity and relevance of these enzymes in multiple biological processes. As part of our studies on the human degradome--which is defined as the complete set of human protease genes--we have recently identified and cloned three complex polyserine proteases called polyserases. Polyserase-...

Background: Proteolytic enzymes have an important role in variety of physiological and pathological functions. They have been used in therapeutic and pharmaceutical applications. Characterizations of extracellular proteases from various strains of S. marcescens indicate that most strains produce a very similar major metalloprotease. This metalloprotease (serrapeptidase, serrapeptase) is an impo...

Serine protease performs normal biological functions in cell. Serine protease are involves in coagulation, inflammation and immunity. Wide variety organisms produce serine proteases including virus, bacteria, animals and plants. Serine proteases are mono-meric enzymes. Serine protease are produced as inactive enzymes called zymogen and transported to other organs where they needed, which are th...

Additional enzymes pretreatment technology can promote the hydrolysis of excess activated sludge, while increasing gas production. Single enzyme pretreatment of sludge, alkaline protease has a better effect of hydrolysis. The optimum working conditions for alkaline protease: pH value of 8.0, the solid-liquid ratio of 1:4, the enzyme concentration of 2%, the working temperature of 55°C, reaction...
