characterization of bacillus brevis with descriptions of bacillus migulanus sp. nov., bacillus choshinensis sp. nov., bacillus parabrevis sp. nov., and bacillus galactophilus sp. nov.thirty-five bacillus brevis strains obtained from culture collections, including protein-producing isolates, were taxonomically studied by using numerical analysis, dna base composition, and dna-dna hybridization. six dna relatedness groups were represented, and these groups correlated well with clusters based on the numerical analysis. the b. brevis strains were separated into b. brevis sensu stricto, four new species, and an unidentified species of the genus bacillus. bacillus migulanus sp. no ...19938494737
proposal for two new genera, brevibacillus gen. nov. and aneurinibacillus gen. nov.16s rrna gene sequences of the type strains of 11 species belonging to the bacillus brevis and bacillus aneurinolyticus groups were determined. on the basis of the results of gene sequence analyses, these species were separated into two clusters. the b. brevis cluster included 10 species, namely, bacillus brevis, bacillus agri, bacillus centrosporus, bacillus choshinensis, bacillus parabrevis, bacillus reuszeri, bacillus formosus, bacillus borstelensis, bacillus laterosporus, and bacillus thermo ...19968863420
reclassification of "bacillus pulvifaciens" group ii as brevibacillus agri.organisms formerly identified as strains of paenibacillus pulvifaciens group ii were reclassified as members of the species brevibacillus agri. the reclassification was based on phylogenetic analysis of 16s rrna gene sequences from selected bacillaceae. the analysis strongly supported placement of group ii strains in the genus brevibacillus. high dna relatedness of 87-100% and close phenotypic similarity demonstrated that group ii strains were members of the species brevibacillus agri.19979058544
polyphasic identification of bacillus and brevibacillus strains from clinical, dairy and industrial specimens and proposal of brevibacillus invocatus sp. nov..thirty-three clinical, dairy and industrial isolates of aerobic endospore-forming bacteria which were unreactive in routine identification tests were characterized genotypically by using amplified rdna restriction analysis (ardra), 16s rdna sequencing and dna-dna reassociation, and phenotypically by using fatty acid methyl ester (fame) analysis, sds-page of whole-cell proteins, api biotype 100 assimilation tests and 16 other routine phenotypic tests. three isolates were identified as strains of ...200212054263
heterotrophic bacteria growing in association with methylococcus capsulatus (bath) in a single cell protein production process.the methanotrophic bacterium methylococcus capsulatus (bath) grows on pure methane. however, in a single cell protein production process using natural gas as methane source, a bacterial consortium is necessary to support growth over longer periods in continuous cultures. in different bioreactors of norferm danmark a/s, three bacteria consistently invaded m. capsulatus cultures growing under semi-sterile conditions in continuous culture. these bacteria have now been identified as a not yet descri ...200212073128
study of the bacterial load in a gelatine production process focussed on bacillus and related endosporeforming genera.gelatine is an animal protein with many industrial applications. previous studies pointed out that endosporeforming bacteria, belonging to the genus bacillus or related genera, might contaminate and survive the production process of gelatine, leading to products of low quality and safety. the aim of this study is to determine the bacterial diversity of contaminants isolated from a gelatine production chain with emphasis on aerobic endosporeforming bacteria. contaminants were isolated from sample ...200212583722
a gene cluster involved in pyrimidine reductive catabolism from brevibacillus agri nchu1002.genes involved in pyrimidine reductive catabolism (pyd) were isolated from a moderate thermophile, brevibacillus agri nchu1002, and nine orfs in an 8.2-kb dna fragment were identified by dna sequence analysis. the pyd gene cluster included three closely spaced orfs, designated pyda, pydb, and pydc, transcribed in the same orientation. based on their amino acid sequence identity and enzyme activity assay, the gene products were identified as dihydropyrimidine dehydrogenase (pyda), dihydropyrimidi ...200312670488
