A novel bacterium, designated strain CA-1T , was isolated from forest soil in Kyonggi University. Cells were strictly aerobic, Gram-stain-negative, catalase-positive, oxidase-negative, non-motile, non-spore-forming, rod-shaped and red-orange-pigmented. Strain CA-1T hydrolysed casein and DNA. It was able to grow at 15-37 °C, pH 5.5-9.0 and at 0-2 % (w/v) NaCl concentration. Flexirubin-type pigments were present. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that strain CA-1T formed a lineage within the family Crocinitomicaceae of the phylum Bacteroidetes that was distinct from Fluviicola hefeinensis MYL-8T (96...

In soy sauce brewing, the results of the fermentation of lactic acid greatly affect the quality of soy sauce. The soy sauce moromi produced with Aspergillus oryzae RIB40 allows the growth of Tetragenococcus halophilus NBRC 12172 but not T. halophilus D10. We isolated and identified heptelidic acid (HA), an inhibitor of glyceraldehyde-3-phosphate dehydrogenase (GAPDH), produced by A. oryzae RIB40 as the growth inhibitor of the salt-tolerant lactic acid bacteria. The growth inhibition of T. halophilus D10 by HA was suggested to be associated with the direct inhibition of GAPDH activity under high salt environment...

Phenotypic and genetic changes during long-term preservation have been observed in microbial strains at culture collections (CCs). It is imperative to verify the effects of these changes on quality of the strains preserved at CCs. In this study, we performed genome-wide single-nucleotide polymorphism (SNP) analysis of different production lots, which had been derived from the same origin and preserved at the NITE Biological Resource Center (NBRC) for a 4-38-year period by the vacuum liquid drying method at 4 °C...

Rhizopus microsporus NBRC 32995 was found to hydrolyze fructooligosaccharides (FOS), as well as sucrose, almost completely into monosaccharides through the production of sufficient amounts of organic acids, indicating that the complete hydrolysis of FOS was caused by the secretion of β-fructofuranosidase from fungal cells. Thus, the sucA gene, encoding a β-fructofuranosidase, was amplified by degenerate PCR, and its complete nucleotide sequence was determined. The total length of the sucA gene was 1590 bp, and the SucA protein of R...
