To shed light on the genetic background behind the virulence and salt tolerance of Staphylococcus equorum, we performed comparative genome analysis of six S. equorum strains. Data on four previously published genome sequences were obtained from the NCBI database, while those on strain KM1031 displaying resistance to multiple antibiotics and strain C2014 causing haemolysis were determined in this study. Examination of the pan-genome of five of the six S. equorum strains showed that the conserved core genome retained the genes for general physiological processes and survival of the species. In this comparative genomic analysis, the factors that distinguish the strains…
Bacillus cereus is well known as a gastrointestinal pathogen that causes food-borne illness. In the present study, we sequenced the complete genome of B. cereus FORC_013 isolated from fried eel in South Korea. To extend our understanding of the genomic characteristics of FORC_013, we conducted a comparative analysis with the published genomes of other B. cereus strains.We fully assembled the single circular chromosome (5,418,913 bp) and one plasmid (259,749 bp); 5511 open reading frames (ORFs) and 283 ORFs were predicted for the chromosome and plasmid, respectively. Moreover, we detected that the enterotoxin (NHE, HBL, CytK) induces food-borne illness with diarrheal symptom, and…
Lactobacillus plantarum is found in various environmental niches such as in the gastrointestinal tract of an animal host or a fermented food. This species isolated from a certain environment is known to possess a variety of properties according to inhabited environment’s adaptation. However, a causal relationship of a genetic factor and phenotype affected by a specific environment has not been systematically comprehended. L. plantarum GB-LP3 strain was isolated from Korean traditional fermented vegetable and the whole genome of GB-LP3 was sequenced. Comparative genome analysis of GB-LP3, with other 14 L. plantarum strains, was conducted. In addition, genomic island regions were…
Engineered Saccharomyces cerevisiae has been used for ethanol production from xylose, the abundant sugar in lignocellulosic hydrolyzates. Development of engineered S. cerevisiae able to utilize xylose effectively is crucial for economical and sustainable production of fuels. To this end, the xylose-metabolic genes (XYL1, XYL2 and XYL3) from Scheffersomyces stipitis have been introduced into S. cerevisiae. The resulting engineered S. cerevisiae strains, however, often exhibit undesirable phenotypes such as slow xylose assimilation and xylitol accumulation. This work was undertaken to construct an improved xylose-fermenting strain by developing a synthetic isozyme system of xylose reductase (XR). The DXS strain having both wild…
Technologies for degradation of three major components of lignocellulose (e.g. cellulose, hemicellulose and lignin) are needed to efficiently utilize lignocellulose. Here, we report Bacillus sp. 275 isolated from a mudflat exhibiting various lignocellulolytic activities including cellulase, xylanase, laccase and peroxidase in the cell culture supernatant. The complete genome of Bacillus sp. 275 strain contains 3832 protein cording sequences and an average G+C content of 46.32% on one chromosome (4045,581bp) and one plasmid (6389bp). The genes encoding enzymes related to the degradation of cellulose, xylan and lignin were detected in the Bacillus sp. 275 genome. In addition, the genes encoding glucosidases…

The fungus Aspergillus persii strain NIBRFGC000004109 is capable of producing penicillic acid and showed antibacterial activity against various plant-pathogenic bacteria, including Xanthomonas arboricola pv. pruni. Here, we report the first draft whole-genome sequence of A. persii The assembly comprises 38,414,373 bp, with 12 scaffolds. Copyright © 2017 Kim et al.
Barnyardgrass (Echinochloa crus-galli) is a pernicious weed in agricultural fields worldwide. The molecular mechanisms underlying its success in the absence of human intervention are presently unknown. Here we report a draft genome sequence of the hexaploid species E. crus-galli, i.e., a 1.27?Gb assembly representing 90.7% of the predicted genome size. An extremely large repertoire of genes encoding cytochrome P450 monooxygenases and glutathione S-transferases associated with detoxification are found. Two gene clusters involved in the biosynthesis of an allelochemical 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and a phytoalexin momilactone A are found in the E. crus-galli genome, respectively. The allelochemical DIMBOA gene cluster is activated…
Research findings on probiotics highlight their importance in repressing harmful bacteria, leading to more extensive research on their potential applications. We analysed the genome of Lactobacillus fermentum SK152, which was isolated from the Korean traditional fermented vegetable dish kimchi, to determine the genetic makeup and genetic factors responsible for the antimicrobial activity of L. fermentum SK152 and performed a comparative genome analysis with other L. fermentum strains. The genome of L. fermentum SK152 was found to comprise a complete circular chromosome of 2092 273 bp, with an estimated GC content of 51.9% and 2184 open reading frames. It consisted of…
This study aimed to determine the complete genome sequence of multidrug-resistant Staphylococcus sciuri strain SNUDS-18 isolated from a farmed duck in South Korea.Genomic DNA was sequenced using a PacBio RS II system.

Staphylococcus equorum KS1039 was isolated from a form of traditional Korean high-salt-fermented seafood called Saeu-jeotgal, and exhibited growth at a NaCl (w/v) concentration of 25%. Comparative genome analyses with two other strains revealed the presence of two potassium voltage-gated channel genes uniquely in KS1039, which might be involved in salt tolerance. This first complete genome sequence of the species will increase our understanding of the genetic factors allowing it to be safely consumed by humans and to inhabit high-salt environments.
