Project description:Here, we report the draft genome sequence of strain NBRC 16556, deposited as Streptomyces hygroscopicus subsp. hygroscopicus into the NBRC culture collection. An average nucleotide identity analysis confirmed that the taxonomic identification is correct. The genome sequence will serve as a valuable reference for genome mining to search new secondary metabolites.
Project description:Alcanivorax sp. strain NBRC 101098 was isolated from seawater in Japan. Strain NBRC 101098 is able to degrade various types of n-alkanes. Here, we report the complete genome of strain NBRC 101098.
Project description:Gluconobacter frateurii strain NBRC 103465 can efficiently produce glyceric acid (GA) from raw glycerol feedstock derived from biodiesel fuel production processes. Here, we report the 3.4-Mb draft genome sequence of G. frateurii NBRC 103465. The draft genome sequence can be applied to examine the enzymes and electron transport system involved in GA production.
Project description:Pseudonocardia autotrophica NBRC 12743 contains a cytochrome P450 vitamin D3 hydroxylase, and it is used as a biocatalyst for the commercial production of hydroxyvitamin D3, a valuable compound for medication. Here, we report the complete genome sequence of P. autotrophica NBRC 12743, which could be useful for improving the productivity of hydroxyvitamin D3.
Project description:Spiroplasma sp. NBRC 100390 was initially described as a duplicate of S. atrichopogonis GNAT3597T (=ATCC BAA-520T) but later found to be different in the 16S rDNA sequences. Here, we report the complete genome sequence of this bacterium to establish its identity and to facilitate future investigation.
Project description:Lactobacillus kosoi NBRC 113063 is a fructophilic species isolated from kôso, a Japanese sugar-vegetable fermented beverage. The draft genome sequence of Lactobacillus kosoi NBRC 113063 is useful for understanding the carbohydrate metabolism of fructophilic lactic acid bacteria.
Project description:Sporolactobacillus inulinus NBRC 111894 is a species of endospore-forming lactic acid bacteria isolated from kôso, a Japanese sugar-vegetable fermented beverage. The draft genome sequence of S. inulinus NBRC 111894 is useful for understanding the differences between S. inulinus strains and their conserved characteristics.
Project description:Gluconacetobacter xylinus is involved in the industrial production of cellulose. We have determined the genome sequence of G. xylinus NBRC 3288, a cellulose-nonproducing strain. Comparative analysis of genomes of G. xylinus NBRC 3288 with those of the cellulose-producing strains clarified the genes important for cellulose production in Gluconacetobacter.
Project description:Most eukaryotic species are colonized by a microbial community - the microbiota - that is acquired during early life stages and is critical to host development and health. Much research has focused on the microbiota biodiversity during the host life, however, empirical data on the basic ecological principles that govern microbiota assembly is lacking. Here we quantify the contribution of colonizer order, arrival time and colonization history to microbiota assembly on a host. We established the freshwater polyp <i>Hydra vulgaris</i> and its dominant colonizer <i>Curvibacter</i> as a model system that enables the visualization and quantification of colonizer population size at the single cell resolution, <i>in vivo</i>, in real time. We estimate the carrying capacity of a single <i>Hydra</i> polyp as 2 × 10<sup>5</sup><i>Curvibacter</i> cells, which is robust among individuals and time. Colonization experiments reveal a clear priority effect of first colonizers that depends on arrival time and colonization history. First arriving colonizers achieve a numerical advantage over secondary colonizers within a short time lag of 24 h. Furthermore, colonizers primed for the <i>Hydra</i> habitat achieve a numerical advantage in the absence of a time lag. These results follow the theoretical expectations for any bacterial habitat with a finite carrying capacity. Thus, <i>Hydra</i> colonization and succession processes are largely determined by the habitat occupancy over time and <i>Curvibacter</i> colonization history. Our experiments provide empirical data on the basic steps of host-associated microbiota establishment - the colonization stage. The presented approach supplies a framework for studying habitat characteristics and colonization dynamics within the host-microbe setting.
