In this study, susceptibility of the first three larval stages of Spodoptera exigua to Bacillus thuringiensis was investigated. To determine the LC50 values for each larval instar, 6 different logarithmic concentrations of Bacillus thuringiensis were used. A control was also included in each of the bioassays. The value of LC50 for 1st instar larvae, that had been treated one to four hours after...

Systematic studies of the Bacillus group have been biased towards terrestrial and pathogenic isolates, and relatively few studies have examined Bacillus species from marine environments. Here we took twenty Bacillus strains from diverse marine environments and sequenced their 16S rRNA. Using molecular comparisons, we separated the strains into thirteen Bacillus genotypes and identified 9 specie...

Food poisoning laboratories identify Bacillus cereus using routine methods that may not differentiate all Bacillus cereus group species. We recharacterized Bacillus food-poisoning strains from 39 outbreaks and identified B. cereus in 23 outbreaks, B. thuringiensis in 4, B. mycoides in 1, and mixed strains of Bacillus in 11 outbreaks.

فیتیک اسید، ماده ای ضد تغذیه ای است که در دانه غلات و حبوبات یافت می شود. این ماده از جذب عناصر معدنی و پروتئین ها در روده جلوگیری کرده و ارزش غذایی ماده مصرف شده را به شدت کاهش می دهد. بنابراین استفاده از روش هایی برای کاهش و حذف این ماده راهی در جهت احیای ارزش غذایی حبوبات وغلات به شمار می آید. آنزیم فیتاز با هیدرولیز فیتیک اسید این کار را به نحوی انجام می دهد که کمترین اثر نامطلوب بر روی ماد...

The bacillus described in this paper occurred in a fatal case of gas gangrene. The cultures were derived from infected muscle at a considerable distance from the wound surface, and no other anaerobes were present in the muscle. The bacillus proved markedly pathogenic for guinea pigs, producing extensive muscle lesions from which pure cultures of the bacillus were always obtained. Thus there is ...

To formulate an efficient and eco-friendly strategy for the management of cotton seedling disease complex, pot experiments were conducted and the efficiency of eight Bacillus strains against seven fungi involved in the disease were determined. A greenhouse evaluation of the interaction between fungal isolates and Bacillus strains was carried out. The evaluation revealed a very highly significan...
