Piscibacter tructae gen. nov., sp. nov., an anaerobic butyrate-producing Fusobacteriaceae bacterium isolated from gut of rainbow trout.
A Gram-stain-negative, anaerobic and rod-shaped bacterium was isolated from gut of rainbow trout in Japan. The temperature range for the growth of 9N8T was 10-30 °C with an optimum at 20 °C. The organism produced acetate and butyrate when grown on AccuDia™ Gifu Anaerobic Medium broth, Modified. Phylogenetic analysis of 16S rRNA gene sequences indicated that strain 9N8T was related to the genus Fusobacterium (<92.9% similarity) and formed a distinct phylogenetic lineage from existing genera within the family Fusobacteriaceae. Strain 9N8T has a genome size of 2.60 Mb. The genomic DNA G+C content was 29.4 mol%. Average amino acid identity values between strain 9N8T and strains in the family Fusobacteriaceae ranged from 39.2 to 57.5%. The major fatty acids of strain 9N8T were C14 : 0, C16 : 1 ω7c and C16 : 0. On the basis of the morphological, physiological, biochemical and genetic information, a novel genus and species, Piscibacter tructae, is proposed, with 9N8T (=NBRC 116745T=DSM 118263T) as the type strain.
期刊介绍:
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
