کیتین، هموپلیمری خطی با اتصالات ?-1و4 n- استیل گلوکز آمین می باشد و دومین پلی ساکارید فراوان طبیعت بعد از سلولز به شمار می رود. کیتین در دیواره سلولی اکثر قارچ ها، حشرات و ... وجود دارد و تجزیه آن به مونومر های ساده تر از لحاظ زیست محیطی بسیار حائز اهمیت است. کیتیناز ها، گلیکوزیل هیدرولازهایی هستند که در طیف وسیعی از موجودات تولید می شوند و تجزیه کیتین را به منابع آلی در دسترس نظیر منابع نیتروژ...

The bio-materials of four marine mangrove medicinal plants viz., Aegiceras Corniculatum (AGC), Excoecariaagallocha (EA), Rhizophoramucronata (RM) and Xylocarpusgranatum (XG) are extracted with methanol and hexane. These extracts are submitted to the antibacterial activity towards the strains:Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis,...

Eight Bacillus strains isolated from Sonoran Desert soil were shown to belong to a previously unidentified species, for which the name Bacillus sonorensis sp. nov. is proposed. The type strain is strain L87-10T (= NRRL B-23154T). On the basis of phenotypic and genetic data, B. sonorensis is most closely related to Bacillus licheniformis. B. sonorensis can be distinguished from B. licheniformis ...

Thirty-five Bacillus isolates were obtained from traditionally fermented locust bean ( ̈iru ̈) in Akure, South-western part of Nigeria. Twelve of the bacillus isolates were identified as Bacillus licheniformis, twentyone as Bacillus subtilis and two as Bacillus cereus according to physiological and biochemical properties. The B. licheniformis isolates were selected for this study due to scarcity ...

BACKGROUND Some strains of Bacillus licheniformis have been improved by target-directed screening as well as by classical genetic manipulation and used in commercial thermostable alpha-amylase and alkaline protease production for over 40 years. Further improvements in production of these enzymes are desirable. RESULTS A new strain of B. licheniformis CBBD302 carrying a recombinant plasmid pHY...

A strain of Bacillus licheniformis, established in the digestive tract of gnotobiotic mice, inhibited the subsequent establishment of a Clostridium perfringens strain ingested by the animals. This inhibitory effect depended on the in vivo production by B. licheniformis of an antibiotic substance having a number of the characteristics of bacitracin. If C. perfringens was the first to become esta...
