Paenibacillus tyrfis YSS-72.2.G2 is a soil chitinolytic bacterium newly isolated from Yok Don National Park of Vietnam. Our previous results demonstrated that this bacterium was a strong chitinase producer, possessed plant growth promotion, and had high activity against phytopathogenic fungi. However, the genome sequence of this strain is unknown. This work aimed to establish data on the genome sequence of P. tyrfis YSS-72.2.G2 and its chitinase system for further assessments regarding biocontrol mechanisms and plant growth promotion. The P. tyrfis YSS-72.2.G2 genome is 7,756,121 bp in size and 53.4 % G+C. It harbors 6,948 protein-coding genes, 5 rRNA genes, 82 tRNA genes, 4 ncRNA genes, 99 pseudo genes, and 5 CRISPR arrays. Genes involved in heavy metal resistance (5 genes), iron acquisition (5 genes), and IAA biosynthesis (5 genes) were predicted in the genome. There were 234 carbohydrate-active enzymes found in this genome; among them, 13 enzymes possibly possess activity against phytopathogens. Chitin-degrading system of YSS-72.2.G2 contains 15 chitinolytic enzymes. In addition, 28 gene clusters coding for antimicrobial metabolites were identified, of these, 14 show no sequence similarities to the known clusters. The raw sequences were submitted to the Sequence Read Archive on the National Center for Biotechnology Information with accession number PRJNA946889. The genome sequence of P. tyrfis YSS-72.2.G2 has been deposited in the DDBJ/GenBank/EMBL database under accession number NZ_BSDJ00000000. Data provide insight into the genomic information of strain YSS-72.2.G2. This is the first work reporting data on the genome sequence of P. tyrfis isolated from Vietnam.

Whole Genome Sequencing of the Novel Probiotic Strain Lactiplantibacillus plantarum FCa3L.

Lactiplantibacillus plantarum is best known for its significant adaptive potential and ability to colonize different ecological niches. Different strains of L. plantarum are widely used as probiotics. To characterize the probiotic potential of the novel L. plantarum FCa3L strain isolated from fermented cabbage, we sequenced its whole genome using the Illumina MiSeq platform. This bacterial isolate had a circular chromosome of 3,365,929 bp with 44.3% GC content and a cyclic phage phiX174 of 5386 bp with 44.7% GC content. The results of in vitro studies showed that FCa3L was comparable with the reference probiotic strain L. plantarum 8PA3 in terms of acid and bile tolerance, adhesiveness, H2O2 production, and acidification rate. The strain 8PA3 possessed higher antioxidant activity, while FCa3L demonstrated superior antibacterial properties. The antibiotic resistance of FCa3L was more relevant to the probiotic strain than that of 8PA3, although a number of silent antibiotic resistance genes were identified in its genome. Genomic evidence to support adhesive and antibacterial properties, biosynthesis of bioactive metabolites, and safety of FCa3L was also presented. Thus, this study confirmed the safety and probiotic properties of L. plantarum FCa3L via complete genome and phenotype analysis, suggesting its potential as a probiotic, although further in vivo investigations are still necessary.

Genomes comparison of two Proteus mirabilis clones showing varied swarming ability.

BACKGROUND: Proteus mirabilis is a Gram-negative bacteria most noted for its involvement with catheter-associated urinary tract infections. It is also known for its multicellular migration over solid surfaces, referred to as 'swarming motility'. Here we analyzed the genomic sequences of two P. mirabilis isolates, designated K38 and K39, which exhibit varied swarming ability. METHODS AND RESULTS: The isolates genomes were sequenced using Illumina NextSeq sequencer, resulting in about 3.94 Mbp, with a GC content of 38.6%, genomes. Genomes were subjected for in silico comparative investigation. We revealed that, despite a difference in swarming motility, the isolates showed high genomic relatedness (up to 100% ANI similarity), suggesting that one of the isolates probably originated from the other. CONCLUSIONS: The genomic sequences will allow us to investigate the mechanism driving this intriguing phenotypic heterogeneity between closely related P. mirabilis isolates. Phenotypic heterogeneity is an adaptive strategy of bacterial cells to several environmental pressures. It is also an important factor related to their pathogenesis. Therefore, the availability of these genomic sequences will facilitate studies that focus on the host-pathogen interactions during catheter-associated urinary tract infections.

Streptomyces solincola sp. nov., isolated from soil in Malaysia.

A urease-producing Gram-stain-positive actinobacterium, designated strain T5T, was isolated from a soil sample collected at a highway hillslope in Selangor, Malaysia. The strain was found to produce pale yellowish-pink aerial mycelia with smooth long chain spores and extensively branched light yellowish-pink substrate mycelia on oatmeal agar. Strain T5T grew at 15-37 °C, pH 6-11, and tolerated up to 9 % (w/v) NaCl, with optimal growth occurring at 28 °C, pH 6-9 and without NaCl. The whole-cell sugar hydrolysate of strain T5T contained galactose, glucose and ribose. The ll-diaminopimelic acid isomer was detected in the cell wall. Diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol were found to be the predominant polar lipids. The main fatty acids were anteiso-C17 : 0, iso-C16 : 0, anteiso-C15 : 0 and iso-C14 : 0. Comparative analysis of the 16S rRNA gene sequences indicated that strain T5T belonged to Streptomyces of the family Streptomycetaceae with the highest 16S rRNA gene sequence similarity to Streptomyces lichenis LCR6-01T (99.0 %). The overall genome relatedness indices revealed that the closest related species was S. lichenis LCR6-01T with 89.4 % average nucleotide identity and 33.7 % digital DNA-DNA hybridization. Phylogeny analyses showed that strain T5T was closely related to Streptomyces fradiae, Streptomyces lavendofoliae, Streptomyces lichenis, Streptomyces roseolilacinus and Streptomyces somaliensis. Based on these polyphasic data, strain T5T represents a novel species, for which the name Streptomyces solincola sp. nov. is proposed. The type strain is T5T (=TBRC 5137T= DSM 42166T).
