Bacteroides amylophilus strain H I 8 produced protease(s), active at pH 7.0, when grown anaerobically in a simple maltose, ammonium sulphate, cysteine, sodium bicarbonate and salts medium. Protease production was neither induced nor repressed by a wide range of nutrients. Protease was synthesized by exponentially growing organisms and 20% of it was liberated into the growth medium. The cell-bou...

background and purpose: today, treatment of life-threatening fungal infections, caused by candida species, has become a major problem. in the present study, we aimed to evaluate the antifungal susceptibility patterns of different clinical candida isolates, determine the virulence factors in multi-drug resistant (mdr) candida species, and assess the anti-biofilm activity of elettaria cardamomum ...

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...

BACKGROUND Many workers have reported halotolerant bacteria from saline conditions capable of protease production. However, antibiotic resistance and heavy metal tolerance pattern of such organisms is not documented very well. Similarly, only a few researchers have reported the pattern of pH change of fermentation medium during the course of protease production. In this study, we have isolated ...

Cellulosimicrobium cellulans is one of the microorganisms that produces a wide variety of yeast cell wall-degrading enzymes, β-1,3-glucanase, protease and chitinase. Dried cells of Saccharomyces cerevisiae were used as carbon and nitrogen source for cell growth and protease production. The medium components KH2PO4, KOH and dried yeast cells showed a significant effect (p<0.05) on the factorial ...

Halophilic microorganisms are recognized as potential source of secondary metabolites including enzymes and drugs with wide agricultural and industrial applications. In the present study protease producing halotolerant bacterium Bacillus licheniformis HSW-16 was isolated from hypersaline Sambhar lake, Rajasthan India. Protease production was performed by using azocasein as substrate. Confirmati...

Plants are increasingly used as alternative expression hosts for the production of recombinant proteins offering many advantages including higher biomass and the ability to perform post-translational modifications on complex proteins. Key challenges for optimized accumulation of recombinant proteins in a plant system still remain, including endogenous plant proteolytic activity, which may sever...

An alkaline protease producing bacterial strain Bacillus licheniformis (MTCC NO. 7053), which was obtained from IMTECH, Chandigarh used for protease production studies. Three significant variables effecting protease production like rice husk (variable 1); inoculum size (variable 2); KNO3 (variable 3) have been identified under preliminary optimization studies. These variables are selected for a...

The influence of growth rate and oxygen availability on siderophore, protease, and lipase production in Burkholderia cepacia was assessed for cells grown in a chemostat under iron limitation. Whereas siderophore and protease production increased with growth rate and oxygen yet decreased under oxygen depletion, lipase production demonstrated the opposite trend.
