A B S T R C Bacterial biofilms are communities of microorganisms residing within a polysaccharide matrix. Dental plaque, slimy coating in tanks, and algal mats on bodies water examples biofilms. It is well accepted that play important role bacterial persistence antibiotic resistance chronic infections. acknowledged the majority microbial cells earth living distinct as In fact, it now known 99% all bacteria exist biofilms, with only 1% planktonic state. has been estimated 65% infections...
Abstract Background Microbial cultures are extensively used as environment friendly ways for biological control of parasitic pests, including the root-knot nematodes, alternative to use chemical nematicides. The present study was conducted isolate some lytic rhizobacteria and examine their nematicidal activity against Meloidogyne incognita J 2 mortality egg hatching in vitro test. Results Lytic Rhizobacteria were isolated from soil samples adhering tomato plant roots different localities at...
In recent years, great emergence of environmental issues such as “green biotechnology” or “white (in EUR) is developed. Green biotechnology can be regarded application microorganisms their metabolites in food, medicine, and pharmaceutical fields. Edible mushroom an ideal food due to the fairly high content proteins include amino acids which are essential human health nutrition. Mushroom fungus easily digested, free cholesterol, provides a source dietary fiber. Fungal compete successfully...
a B S t r c Bacillus alvei NRC-14, soil bacterial isolate, was found to exhibit multipleadaptive response when exposed abiotic stress factors. In the present study, chemical and flocculation properties of viscous biopolymer flocculant produced by strain under cold-shock are investigated. Addition sucrose or starch at 1% concentration increased growth viscosity. The is polysaccharide as indicated sugars content. Maximum values viscosity flocculating activity were obtained pH range from 5-9....
Bacillus alvei, a potent chitosanase producer, secreted an extracellular chitosan-degrading enzyme in the absence of chitosan. Extracellular secretion reached levels corresponding to 2.3 U/ml after less than two days. The was purified by precipitation with ammonium sulfate followed CM-cellulose chromatography. Two chitosanases, A and B were from culture fluid. Chitosanase exhibited substrate specificity for chitosan, while possessed comparable specific activities toward glycol chitin...
