Clostridium amazonense sp. nov. an obliqately anaerobic bacterium isolated from a remote Amazonian community in Peru.

ABSTRACT: A strictly anaerobic Gram-stain positive, spore-forming, rod-shaped bacterium designated NE08V(T), was isolated from a fecal sample of an individual residing in a remote Amazonian community in Peru. Phylogenetic analysis based on the 16S rRNA gene sequence showed the organism belonged to the genus Clostridium and is most closely related to Clostridium vulturis (97.4% sequence similarity) and was further characterized using biochemical and chemotaxonomic methods. The major cellular fatty acids were anteiso C13:0 and C16:0 with a genomic DNA G + C content of 31.6 mol%. Fermentation products during growth with PYG were acetate and butyrate. Based on phylogenetic, phenotypic and chemotaxonomic information, strain NE08V was identified as representing a novel species of the genus Clostridium, for which the name Clostridium amazonense sp. nov. is proposed. The type strain is NE08V(T) (DSM 23598(T) = CCUG 59712(T)).

Project description:Background:Cassava pulp is a promising starch-based biomasses, which consists of residual starch granules entrapped in plant cell wall containing non-starch polysaccharides, cellulose and hemicellulose. Strain CT4T, a novel mesophilic anaerobic bacterium isolated from soil collected from a cassava pulp landfill, has a strong ability to degrade polysaccharides in cassava pulp. This study explored a rarely described species within the genus Clostridium that possessed a group of cassava pulp-degrading enzymes. Methods:A novel mesophilic anaerobic bacterium, the strain CT4T, was identified based on phylogenetic, genomic, phenotypic and chemotaxonomic analysis. The complete genome of the strain CT4T was obtained following whole-genome sequencing, assembly and annotation using both Illumina and Oxford Nanopore Technology (ONT) platforms. Results:Analysis based on the 16S rRNA gene sequence indicated that strain CT4T is a species of genus Clostridium. Analysis of the whole-genome average amino acid identity (AAI) of strain CT4T and the other 665 closely related species of the genus Clostridium revealed a separated strain CT4T from the others. The results revealed that the genome consisted of a 6.3 Mb circular chromosome with 5,664 protein-coding sequences. Genome analysis result of strain CT4T revealed that it contained a set of genes encoding amylolytic-, hemicellulolytic-, cellulolytic- and pectinolytic enzymes. A comparative genomic analysis of strain CT4T with closely related species with available genomic information, C. amylolyticum SW408T, showed that strain CT4T contained more genes encoding cassava pulp-degrading enzymes, which comprised a complex mixture of amylolytic-, hemicellulolytic-, cellulolytic- and pectinolytic enzymes. This work presents the potential for saccharification of strain CT4T in the utilization of cassava pulp. Based on phylogenetic, genomic, phenotypic and chemotaxonomic data, we propose a novel species for which the name Clostridium manihotivorum sp. nov. is suggested, with the type strain CT4T (= TBRC 11758T = NBRC 114534T).
