Nineteen thermophilic, aerobic, endospore-forming bacterial strains were subjected to 16S rRNA gene sequence analysis. Eight of these strains had been received as cultures of Geobacillus kaustophilus, G. lituanicus, G. stearothermophilus, 'G. thermoleovorans subsp. stromboliensis', G. vulcani, 'Bacillus caldolyticus', 'B. caldotenax' and 'B. caldovelox', but they showed close relationships with...
باکتری ها کارخانه های بی همتای بیولوژیک در تولید محصولات زیست فناوری هستند ویژگی-هایی نظیر تحمل شرایط خاص رشد و تولید آنزیم های مختلف، باکتریها را برای بهره برداری مورد توجه قرار داده است. عده ای از باکتری ها واجد عوامل ژنتیکی با قابلیت جابه جایی هستند. نظیر اینترون های گروه ii که سه آنزیم با ارزش وارونوشتاز , ( reverse transcriptase) اندونوکلئاز ,(endonuclease) مچوراز (maturase) رارمز می کنن...
Host-controlled restriction and modification of TP-1C phage and infectious phage DNA occurs in Bacillus stearothermophilus and is subject to control by TP-8 or TP-12 prophage.
Geobacillus stearothermophilus strains 22 and 53 were isolated from sediment samples isolated from the Garga hot spring (72°C) located in the valley of the river Barguzin (the Baikal region, Russian Federation) (54°19'3.72″N, 110°59'38.4″E).
The heat resistances of the fully demineralized H-form spores of Bacillus megaterium ATCC 19213, B. subtilis var. niger, and B. stearothermophilus ATCC 7953 were compared with those of vegetative cells and native spores to assess the components of resistance due to the mineral-free spore state, presumably mainly from dehydration of the spore core, and to mineralization. Mineralization greatly i...
Studies of bacteriophages GH5 and GH8 of Bacillus stearothermophilus strain NCA1518 revealed that their properties were sufficiently different from known phages and from each other to indicate that each was a different entity, although no major deviation was demonstrated.
Spores of thermophilic spore-forming bacteria are a common cause of contamination in dairy products. Here, we report draft genome sequences of four thermophilic strains from a milk-processing plant or standard milk, namely, a Geobacillus thermoglucosidans isolate (TNO-09.023), Geobacillus stearothermophilus TNO-09.027, and two Anoxybacillus flavithermus isolates (TNO-09.014 and TNO-09.016).
Bacillus stearothermophilus BR219, isolated from river sediment, degraded phenol at levels to 15 mM at a rate of 0.85 mumol/h (4 x 10(6) cells). The solubilized phenol hydroxylase was NADH dependent, exhibited a 55 degrees C temperature optimum for activity, and was not inhibited by 0.5 mM phenol.
The 5 A resolution crystal structure analysis of ribosomal protein L30 from Bacillus stearothermophilus is described. The molecule is shown to be compact and extend to about 25-30 A in each dimension.
