Project description:To date, a large number of Bacillus species from different sources have been identified. However, there are few investigations on genome information and evolutionary insights of Bacillus species from cold environments. Bacillus sp. TK-2, isolated from the soil of Changbai Mountain, is a gram-positive bacterium with cold adaptation characteristics. In this study, we present the annotated complete genome sequence of Bacillus sp. TK-2. The genome comprised 5,286,177 bp with a GC content of 35.88%, 5293 protein-encoding genes, 32 rRNA, and 77 tRNA. Numerous genes related to cold adaptation were detected in the genome of Bacillus sp. TK-2, mainly involving in energy supply, regulation of cell membrane fluidity, antioxidant, and molecular chaperones. In addition, the strain TK-2 classified in the Bacillus groups was distributed on a terminal branch with Bacillus cereus A1 by Blastn and phylogenetic analysis in NCBI database. Complete genome sequences of the strain TK-2 and Bacillus cereus A1 were compared by the online tool "Average Nucleotide Identity", showing that the average nucleotide identity of these two strains was 98.26%. In parallel, A comparative analysis of the genomes of both Bacillus sp. TK-2 and Bacillus cereus A1 was conducted. Through the analysis of core and specific genes with cd-hit, it was found that the two strains had 5691 pan gene, 4524 core gene, and 1167 specific gene clusters. Among the 624 specific gene clusters of Bacillus sp. TK-2, some cold tolerance genes were detected, which implied the unique adaptability of Bacillus sp. TK-2 in long-term low temperature environments. Importantly, enzyme-encoding genes related to the degradation of polysaccharides such as cellulose and hemicellulose were detected in the 477 CAZyme genes of this genome. This work on sequencing and bioinformatics analysis of the complete sequence of Bacillus sp. TK-2 promote the application and in-depth research of low-temperature biotechnology.
Project description:We present the draft genome sequence for Bacillus sp. strain PF3, Bacillus sp. strain K6W, Cellulomonas sp. strain B12, Cellulomonas sp. strain K38, Cellulomonas sp. strain K39, and Cellulomonas sp. strain K42B. These bacteria were isolated from contaminated soils, and their genomes contain genes related to chromate transport and reduction.
Project description:Bacillus sp. strain ISO11, a Bacillus cereus clade member isolated from the intestinal tract of Fundulus heteroclitus, possesses potential probiotic and antibacterial activity against Vibrio sp. pathogens. Antibacterial activity is likely due to production of microcin and a zwittermicin A-like aminopolyol. The genome sequence will assist in identifying additional related processes.
Project description:Strain EB01(T) sp. nov. is the type strain of Bacillus massilioalgeriensis, a new species within the genus Bacillus. This strain, whose genome is described here, was isolated from sediment sample of the hypersaline lake Ezzemoul sabkha in northeastern Algeria. B. massilioalgeriensis is a facultative anaerobic Gram-positive bacillus. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 5,269,577 bp long genome contains 5,098 protein-coding and 95 RNA genes, including 12 rRNA genes.
Project description:The draft genome sequence of Bacillus sp. VKPM B-3276, a mesophilic, gram-positive bacterium, isolated from dead Culex pipiens larvae is presented. This strain was deposited in the Russian National Collection of Industrial Microorganisms as a prospective candidate for development of new entomopathogenic agents. The genome of Bacillus sp. VKPM B-3276 was 6,126,346 bp in length with predicted completeness of 99.43%. Genome analysis identified 6518 protein-coding sequences and 111 RNAs genes. 13% (271) of the protein-coding genes were assigned to "Carbohydrates" subsystem category, according to RAST/SEED. Among them about 50 enzymes, responsible for chitin, peptidoglycan and related molecules decomposition, were found. The draft genome of strain VKPM B-3276 was deposited at DBJ/EMBL/GenBank under the accession nos. RZHM00000000, PRJNA511803 and SAMN10644103 for Genome, Bioproject and Biosample, respectively.
Project description:Bacillus sp. strain QHF158, a Gram-positive, spore-forming and parasporal crystal-secreting bacterium, was isolated from soil of Limushan National Forest Park in China. Here we present the significant feature of parasporal inclusions of this organism, together with the draft genome sequence and annotation. Phylogenetic analysis suggested that strain QHF158 is possibly a novel species, most closely related to Bacillus mycoides. Genome annotation results revealed that strain QHF158 did not contain any typical Cry or Cyt toxin coding gene. Furthermore, the mass spectrometry analyses demonstrated that the parasporal crystalline inclusions were encoded by the orf_05273 gene, with 95% similarity to the S-layer protein (SLP) EA1 of B. mycoides, which indicated that the parasporal crystal from Bacillus sp. strain QHF158 was mainly formed by SLP, instead of the typical Cry or Cyt toxin proteins.
Project description:Bacillus timonensis strain MM10403188(T) sp. nov. is the type strain of a proposed new species within the genus Bacillus. This strain, whose genome is described here, was isolated from the fecal flora of a healthy patient. B. timonensis is an aerobic Gram-negative rod shaped bacterium. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 4,632,049 bp long genome (1 chromosome but no plasmid) contains 4,610 protein-coding and 74 RNA genes, including 5 rRNA genes.
Project description:Gram-negative bacteria can communicate with each other by N-acyl homoserine lactones (AHLs), which are quorum-sensing autoinducers. Recently, the aiiA gene (encoding an enzyme catalyzing the degradation of AHL) has been cloned from Bacillus sp. strain 240B1. During investigations in the course of the ongoing Bacillus thuringiensis subsp. morrisoni genome project, an aiiA homologue gene in the genome sequence was found. These results led to consideration of the possibility of the widespread existence of the gene in B. thuringiensis. aiiA homologue genes were found in 16 subspecies of B. thuringiensis, and their sequences were determined. Comparison of the Bacillus sp. strain 240B1 aiiA gene with the B. thuringiensis aiiA homologue genes showed high homologies of 89 to 95% and 90 to 96% in the nucleotide sequence and deduced amino acid sequence, respectively. Among the subspecies of B. thuringiensis having an aiiA gene, the subspecies aizawai, galleriae, kurstaki, kyushuensis, ostriniae, and subtoxicus were shown to degrade AHL. It was observed that recombinant Escherichia coli producing AiiA proteins also had AHL-degrading activity and could also attenuate the plant pathogenicity of Erwinia carotovora. These results indicate that insecticidal B. thuringiensis strains might have potential to compete with gram-negative bacteria in natural ecosystems by autoinducer-degrading activity.
