Strains from four different DNA relatedness groups of Bacillus circulans showed apparent alginate lyase activity; the activity of three strains examined had mannuronidase specificity. A representative strain of group 4 also produced apparent inducible unsulfated chrondroitin lyase activity.

Bioaccumulation of Cd(2+) in soil bacteria might represent an important route of metal transfer to associated mycorrhizal fungi and plants and may have potential as a tool to accelerate Cd(2+) extraction in the bioremediation of contaminated soils. The present study examined the bioaccumulation of Cd(2+) in 15 bacterial strains representing three phyla (Firmicutes, Proteobacteria, and Bacteroid...

The distribution and substrate specificities of enzymes involved in the formation of linkage units which contain N-acetylglucosamine (GlcNAc) and N-acetylmannosamine (ManNAc) or glucose and join teichoic acid chains to peptidoglycan were studied among membrane systems obtained from the following two groups of gram-positive bacteria: group A, including Bacillus subtilis, 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 ...

Five Bacillus strains isolated from Death Valley soil were shown to belong to a previously unidentified species, for which we propose the name Bacillus vallismortis. The type strain is strain DVI-F-3 (= NRRL B-14890). On the basis of previously published restriction digestion data, B. vallismortis is most closely related to Bacillus subtilis. At this time B. vallismortis can be distinguished fr...

The effect of bacterial strains on certain genera, both independently and in combination with biochar various options, petroleum hydrocarbon decomposition chernozem the restoration ecological state soil were studied. To simulate contamination, hydrocarbons introduced into amount 5% weight. Strains Bacillus Paenibacillus bacteria (in recommended increased doses × 100) (1% weight) contaminated se...

Soil samples with temperatures up to 64 degrees C were collected from Mount Erebus, an active volcano located on Ross Island, Antarctica. Acridine orange direct counts and most probable number counts of soil samples stored at 4 degrees C for 2 months showed a wide variation in the number of thermophilic microorganisms in different soils. Organisms similar to Clostridium thermohydrosulfuricum, B...

Five Bacillus strains isolated from Death Valley soil were shown to belong to a previously unidentified species, for which we propose the name Bacillus vallismortis. The type strain is strain DV1-F-3 (= NRRL B-14890). On the basis of previously published restriction digestion data, B. vallismortis is most closely related to Bacillus subtilis. At this time B. vallismortis can be distinguished fr...
