Effect of glycoside hydrolase 18 chitinase on alternately β-1,4-linked glucose and N-acetylglucosamine derived from the sulfur-oxidizing bacterium Thiothrix nivea
The filamentous sulfur-oxidizing bacterium Thiothrix nivea produces glucosaminoglucan (GG), which is β-1,4-linked copolymer of glucose and glucosamine. GG is a major component of the sheath which covers the bacterial filament, and the ba...

Verification of optimal pre-enrichment culture inoculum size for tetrathionate broth and selenite broth to isolate Salmonella enterica by spike test and field trial
The isolation efficiency of Salmonella enterica using selective enrichment media varies depending on culture conditions. Tetrathionate broth (TTB) and selenite broth (SB) differ in selectivity and growth support, yet practical guidance o...

Developing an assay system for screening inhibitors of Hfq-mediated RNA metabolism
Hfq is an RNA chaperone conserved across diverse bacterial lineages that regulates gene expression by facilitating the pairing of small RNAs with their target mRNAs. It influences both the translation and stability of specific transcript...

Bioinformatics analysis of extracellular glycosyl hydrolases mined from the genome of Halophilic Meridianimaribacter sp. CL38
Biological pre-treatment of lignocellulosic waste is crucial for efficient fermentation in second-generation biofuel production. Halophilic bacteria produce glycosyl hydrolases with enhanced stability for industrial application. This stu...

Development of a small mobilizable plasmid system: A foundation for genetic engineering of Bacillus subtilis strains
Although Bacillus subtilis natto is a highly beneficial probiotic bacterium, its genetic engineering is heavily constrained by low natural transformability. To provide a competence-independent route for DNA delivery, we developed a minim...

Bacillus subtilis var. natto as a naturally optimized biotin biosensor
Bacillus subtilis var. natto is a naturally occurring biotin auxotroph widely used in traditional soybean fermentation. In this study, we evaluated its potential as a microbial biotin biosensor without genetic modification. Using a two-l...

Biotin Dependency Shapes Sporulation Kinetics in Bacillus subtilis var. natto
Bacillus subtilis var. natto is distinguished from other B. subtilis strains by the inability to synthesize biotin. To investigate the evolutionary origin and functional consequences of this auxotrophy, we performed a comparative genomic...

FAS2-1280F mutation in the fatty acid synthase gene, FAS2, of Saccharomyces cerevisiae enhances caprylic acid production
To produce new types of sake with a fruity aroma, imparted mainly by ethyl caprylate, a novel cerulenin-resistant strain, NSYC8, was isolated. NSYC8 produces high levels of caprylic acid, the precursor of ethyl caprylate, from the sake y...

Reversible dissociation of peripheral subunits from the photosynthetic reaction center of the green sulfur bacterium Chlorobaculum tepidum
The photosynthetic reaction center (RC) of green sulfur bacteria is divided into two parts: the membrane-embedded RC core (RCC) complex (comprising PscA and PscC) and the water-soluble peripheral subunits (comprising the trimeric Fenna–M...
