Jeotgalibacillus spp. are halophilic bacteria within the family Planococcaceae. No genomes of Jeotgalibacillus spp. have been reported to date, and their metabolic pathways are unknown. How the bacteria survive in hypertonic conditions such as seawater is yet to be discovered. As only few studies have been conducted on Jeotgalibacillus spp., potential applications of these bacteria are unknown. Here, we present the complete genome of J. malaysiensis D5(T) (=DSM 28777(T) =KCTC 33350(T)), which is invaluable in identifying interesting applications for this genus.

The genome sequence of Bacillus thuringiensis serovar tolworthi strain Pasteur Institute Standard was determined. The genome consists of a 5.9-Mb chromosome and eight plasmids, one of which is linear. The second largest plasmid (293 kb) carries the genes encoding insecticidal proteins.

Bacillus subtilis, which belongs to the phylum Firmicutes, is the most widely studied Gram-positive model organism. It is found in a wide variety of environments and is particularly abundant in soils and in the gastrointestinal tracts of ruminants and humans. Here, we present the complete genome sequence of the newly described B. subtilis strain UD1022. The UD1022 genome consists of a 4.025-Mbp chromosome, and other major findings from our analysis will provide insights into the genomic basis of it being a plant growth-promoting rhizobacterium (PGPR) with biocontrol potential.

Bacillus thuringiensis is an important microbial biopesticide for controlling agricultural pests by the production of toxic parasporal crystals proteins.Here,we report the finished annotated genome sequence of B. thuringiensis YC-10,which is highly toxic to nematodes.The complete genome sequence consists of a circular chromosome and nine circular plasmids,which the biggest plasmid harbors six parasporal crystals proteins genes consisting of cry1Aa, cry1Ac, cry1Ia, cry2Aa, cry2Ab and cryB1. The crystals proteins of Cry1Ia and Cry1Aa have high nematicidal activity against Meloidogyne incognita. Copyright © 2015 Elsevier B.V. All rights reserved.
Respiratory infectious diseases are the third cause of worldwide death. The nasopharynx is the portal of entry and the ecological niche of many microorganisms, of which some are pathogenic to humans, such as Neisseria meningitidis and Moraxella catarrhalis. These microbes possess several surface structures that interact with the actors of the innate immune system. In our attempt to understand the past evolution of these bacteria and their adaption to the nasopharynx, we first studied differences in cell wall structure, one of the strongest immune-modulators. We were able to show that a modification of peptidoglycan (PG) composition (increased proportion of pentapeptides)…
Bacillus strains have been widely used as the companion strain of Ketogulonigenium vulgare in the process of vitamin C fermentation. Different Bacillus strains generate different effects on the growth of K. vulgare and ultimately influence the productivity. First, we identified that Bacillus endophyticus Hbe603 was an appropriate strain to cooperate with K. vulgare and the product conversion rate exceeded 90% in industrial vitamin C fermentation. Here, we report the genome sequencing of the B. endophyticus Hbe603 industrial companion strain and speculate its possible advantage in the consortium. The circular chromosome of B. endophyticus Hbe603 has a size of 4.87 Mb…
Bacillus thuringiensis is a spore-forming bacterium that is a type of insect pathogen used in the field of microbial insect control. B. thuringiensis HS18-1 has effective toxicity for Lepidoptera and Diptera insects. It contains different types of parasporal crystal genes, including cry4Cb1, cry50Aa1, cry69Ab1, cry30Ga, cry30Ea, cry70Aa, cry71Aa, cry72Aa, cry56Aa and cry54Ba. Here, we report the complete genome sequence of B. thuringiensis HS18-1, which contains one circular gapless chromosome and nine circular plasmids. Copyright © 2015. Published by Elsevier B.V.
Due to abundant contamination in various foods, the pathogenesis of Bacillus cereus has been widely studied in physiological and molecular level. B. cereus FORC_005 was isolated from a Korean side dish, soy sauce braised fish-cake with quail-egg in South Korea. While 21 complete genome sequences of B. cereus has been announced to date, this strain was completely sequenced, analyzed, and compared with other complete genome sequences of B. cereus to elucidate the distinct pathogenic features of a strain isolated in South Korea. The genomic DNA containing a circular chromosome consists of 5,349,617-bp with a GC content of 35.29 %. It was…
Bacillus subtilis LM 4-2, a Gram-positive bacterium was isolated from a molybdenum mine in Luoyang city. Due to its strong resistance to molybdate and potential utilization in bioremediation of molybdate-polluted area, we describe the features of this organism, as well as its complete genome sequence and annotation. The genome was composed of a circular 4,069,266 bp chromosome with average GC content of 43.83 %, which included 4149 predicted ORFs and 116 RNA genes. Additionally, 687 transporter-coding and 116 redox protein-coding genes were identified in the strain LM 4-2 genome.
Bacillus methylotrophicus JJ-D34 showing good proteolytic and antipathogenic activities was isolated from doenjang, a Korean traditional fermented soybean paste.

Bacillus subtilis contains three subspecies, i.e., subspecies subtilis, spizizenii, and inaquosorum. As these subspecies are phenotypically indistinguishable, their differentiation has relied on phylogenetic analysis of multiple protein-coding gene sequences. B. subtilis subsp. inaquosorum is a recently proposed taxon that encompasses strain KCTC 13429(T) and related strains, which were previously classified as members of subspecies spizizenii. However, DNA-DNA hybridization (DDH) values among the three subspecies raised a question as to their independence. Thus, we evaluated the taxonomic status of subspecies inaquosorum using genome-based comparative analysis. In contrast to the previous experimental values of DDH, the inter-genomic relatedness inferred by average nucleotide…
