In this study, four strains of A. oryzae in group 1 and four in group 3 were point inoculated on equivalent medium (pH 7.3) with two commercially available HAs. The growth of RIB40 was the most stimulated among group 1 strains and that of RIB143 was the most inhibited among group 3 strains. To identify the basis of these differences, we examined the possible effects of HA subcomponents including polyphenol and minerals on the growth of RIB40 and RIB143. Polyphenol represented by gallic acid (GA), a partial structure common with model HA, and mineral ions including Al 3+ , Ca 2+ , Ti 4+ , Mn 2+ , Sr 2+ , and Ba2+ contribute...

Geographical variation of bacterial and ciliophoran communities in tidal flats in a continental archipelago
J Gen Appl Microbiol. 2023 Jul 19. doi: 10.2323/jgam.2023.07.002. Online ahead of print.ABSTRACTIn tidal flats, which are located at the transition zone between terrestrial and marine ecosystems, environmental factors such as temperature, sediment particle size, and tidal range exhibit geographic variation. Accordingly, the composition and structure of the microbial communities in the tidal flats are likely to vary in geographically different habitats. To clarify these differences with environmental factors causing them, we analyzed microbial communities consisting of bacteria and ciliates in sediments collected from nine ...

ThermusQ: Toward the cell simulation platform for Thermus thermophilus
J Gen Appl Microbiol. 2023 Jul 14. doi: 10.2323/jgam.2023.07.001. Online ahead of print.ABSTRACTThermusQ is a website that aims to gather all the molecular information on Thermus thermophilus and to provide a platform to easily access the whole view of the bacterium. ThermusQ comprises the genome sequences of 22 strains from T. thermophilus and T. oshimai strains, plus the sequences of known Thermus phages. ThermusQ also contains information and map diagrams of pathways unique to Thermus strains. The website provides tools to retrieve sequence data in different ways. By gathering the whole data of T. thermophilus strains, ...

Isolation and genomic analysis of a type IV pili-independent Thermus thermophilus phage, φMN1 from a Japanese hot spring
J Gen Appl Microbiol. 2023 Jul 7. doi: 10.2323/jgam.2023.06.008. Online ahead of print.ABSTRACTA Thermus thermophilus lytic phage was isolated from a Japanese hot spring by using a type IV pili-deficient strain as an indicator host, and designated as φMN1. Electron microscopic (EM) examination revealed that φMN1 had an icosahedral head and a contractile tail, suggesting that φMN1 belonged to Myoviridae. An EM analysis focused on φMN1 adsorption to the Thermus host cell showed that the receptor molecules for the phage were uniformly distributed on the outer surface of the cells. The circular double-stranded DNA of φMN1...
