The tremendous mounting interest in lipase production is pertinent to the biotechnological applications that these enzymes offer. Lipase, belonging to the hydrolyze enzymes, is involved in copious biological functions including: hydrolysis insoluble triacylglycerol to mono and diacylglycerols and glycerol. Submerge fermentation technique was applied for the efficient production of this. Briefly...

From the ethyl acetate extract of the bacterial strain Cytophaga sp. AM13.1, among many known compounds, the new natural products 2,5-bis(3-indolylmethyl)pyrazine (2) and a highly symmetrical p-cyclophane named pharacine (5) were identified. In addition, tryptamine isovalerate (1) and p-hydroxyphenylacetamide (4), known as plant metabolites, were isolated and characterized from a microorganism ...

lipases are diversified enzymes in their properties and substrate specificity, which make them attractive tools for various industrial applications. in this study, an alkaline thermostable lipase producing bacteria were isolated from soil of different regions of isfahan province (iran) and its lipase was purified by ammonium sulfate precipitation and ion exchange chromatography. to select a the...

Background: Lipase is an enzyme with immense application potential. Ester synthesis by lipase catalysis in organic media is an area of key industrial relevance. Enzymatic preparations with traits that cater to the needs of this function are hence being intensely researched. Objective: The objectives of the study were to immobilize the lipase from Bacillus sp. PS35 by cross-linking and adsorpti...

The present study was undertaken to screen the soil samples collected in Iran for the presence of the Bacillus subtilis lipase A gene. The bacterial colonies obtained from the collected soil samples were examined by physical appearance, biochemical tests and  the polymerase chain reaction (PCR). Only four colonies were identified as putative B. subtilis strains and all contained the lipase A ge...

Lipoprotein lipase activity in adipose tissue responds rapidly to changes in the physiological state. To study what mechanisms are involved in the regulation, guinea pigs were fasted and the decrease in adipose-tissue lipoprotein lipase activity was compared with the decreases in mRNA and lipase synthesis. The mRNA pattern (three species) did not change. There was a close parallelism between th...

Milk clotting enzyme (M CE) produced by: Rhizomucor miehei was purified and characterized.The enzyme was purified 220.29-fold with specific activity about 14444.2 U/mg protein byultrafiltration, ammonium sulfate fractionation, Sephacryl S-300 chromatography. The maximumenzyme activity was at 65°C.The milk clotting activity was decreased steadily as pH is increased and indicated maximumactivity ...

Pseudomonas aeruginosa EF2, ATCC 9027 and ATCC 19660 were grown in a continuous culture under Tween 80 (polyoxyethylene sorbitan monooleate) limitation and optimum conditions (pH 6.5, 37°C at dilution rate of 0.05/h). Culture supernatants were carefully removed and stored at -20°C. To purify the lipases, the culture supernatant was reduced in volume to approximately 10 mL by an ultrafiltra...
