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...

The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...

In fermented products containing Bifidobacteria, factors such as organic acid concentration and b-galactosidase activity are important in the development of flavor and texture of final products. Both the process conditions and medium components have significant effects on fluctuation of such factors. The effects of whey permeate powder and yeast extract concentrations, as nitrogen sources was i...

Fermented foods are known worldwide for their functional health properties. In order to promote the relative product development of edible grass, Lactobacillus plantarum (Lp) and rhamnosus (Lr) were used ferment grass in this study. Effects fermentation using Lp Lr monoculture binary mixture on physicochemical properties, contents compounds antioxidant activity at different times investigated b...

The effect on methanogens attached to the surface of rumen ciliate protozoa by the addition of plant extracts (pine needles and ginkgo leaves) was studied with particular reference to their effectiveness for decreasing methane emission. The plant extracts (pine needles and ginkgo leaves) were added to an in vitro fermentation incubated with rumen fluid. The microbial population including bacter...

The objective of this study was to evaluate the effects of different concentrations of DL-malate (disodium salt) on the in vitro mixed ruminal microorganism fermentation of soluble starch or cracked corn. Ruminal fluid was collected from a steer fed 6.8 kg of forage and 2.3 kg of concentrate supplement once daily, and mixed ruminal microorganisms were incubated in anaerobic media (40 mL) that c...

The seeds of cotton (Gossypium hirsutum) fall among the lesser known oil seeds. Cottonseeds are not normally consumed in their natural state due to their gossypol content, an antinutrient. The effect of processing on the sensory characteristics and chemical composition of cottonseed and its extract was studied by subjecting the cottonseed extract to heat treatment (boiling) and the cottonseed t...

Ivermectin (MK-0933, 22, 23-dihydroderivative of amvermectin B1) is a synthetic derivative of a broadspectrum antiparasitic class of macro cyclic lactones known as avermectins. Avermectin B was first isolated by fermentation of a soil microorganism, the actinomycete Streptomyces avermitilis. Ivermectin has a structure similar to that of macrolide antibiotics, but without antibacterial activity ...

Staphylococcus xylosus is a bacterial species used in meat fermentation and a commensal microorganism found on animals. We present the first complete circular genome from this species. The genome is composed of 2,757,557 bp, with a G+C content of 32.9%, and contains 2,514 genes and 79 structural RNAs.
