Taxonomy of psychrophilic strains of Bacillus.
نویسندگان
چکیده
The morphological and physiological characteristics of 20 isolates of psychrophilic Bacillus were compared with 29 strains representing nine species of mesophilic Bacillus and 2 strains of Sporosarcina ureae to determine the taxonomic position of the psychrophiles. The psychrophiles formed four distinct groups which were sufficiently different from the mesophiles to warrant their designation as new species of Bacillus. The names B. psychrosaccharolyticus, B. insolitus, B. globisporus, and B. psychrophilus are proposed for the new species.

Draft Genome Sequence of Sporosarcina globispora W 25T (DSM 4), a Psychrophilic Bacterium Isolated from Soil and River Water
Sporosarcina globispora W 25(T) (DSM 4) is a Gram-positive, round-spore-forming, and psychrophilic bacterium. Here, we report the 5.66-Mb genome sequence of S. globispora W 25(T), which will accelerate the application of this psychrophile and provide useful information for genomic taxonomy and phylogenomics of Bacillus-like bacteria.

Larkin, J. M. (Washington State University, Pullman), and J. L. Stokes. Isolation of psychrophilic species of Bacillus. J. Bacteriol. 91:1667-1671. 1966.-Ninety psychrophilic isolates of Bacillus were obtained from soil, mud, and water by selective enrichment at 0 C. They grew well at 0 C, optimally at 20 to 25 C, and failed to grow at 30 or 35 C. Their minimal and maximal growth temperatures w...
متن کاملPhylogeny of Bacillus sphaericus-like organisms.
The mesophilic round-spored bacteria embrace four species, namely Bacillus sphaericus, Bacillus fusiformis, Bacillus silvestris and Bacillus pasteurii. Although not displayed by all strains, mosquito pathogenicity is a noteworthy characteristic of B. sphaericus sensu lato. Phylogenetic analysis based on 16S rDNA sequences from 58 strains identified as B. sphaericus was used to examine the genet...
متن کاملGrowth of Serratia liquefaciens under 7 mbar, 0°C, and CO2-enriched anoxic atmospheres.
Twenty-six strains of 22 bacterial species were tested for growth on trypticase soy agar (TSA) or sea-salt agar (SSA) under hypobaric, psychrophilic, and anoxic conditions applied singly or in combination. As each factor was added to multi-parameter assays, the interactive stresses decreased the numbers of strains capable of growth and, in general, reduced the vigor of the strains observed to g...

Cyanobacterial diazotrophs play a significant role in environmental nitrogen economy despite their habitat either tropical or polar. However, the phenomenon by which it copes with temperature induced stress is poorly understood. Temperature response study of psychrophilic and mesophilic Nostoc strains explores their adaptive mechanisms. The selected psychrophilic and mesophilic strains were con...
