Phenotypic and phylogenetic studies were performed on new isolates of a novel Gram-stain-positive, anaerobic, non-sporulating, rod-shaped bacterium isolated from a thermophilic biogas plant. The novel organisms were able to degrade crystalline cellulose. 16S rRNA gene comparative sequence analysis demonstrated that the isolates formed a hitherto unknown subline within the family Lachnospiraceae. As a representative of the whole group of isolates, strain T3/55T was further characterized. The…

Herbinix luporum sp. nov., a thermophilic cellulose-degrading bacterium isolated from a thermophilic biogas reactor.

Phylogenetic studies were performed on a group of novel Gram-stain-positive, anaerobic, non-sporulating rod-shaped bacteria isolated from a thermophilic biogas plant, finding that they were able to degrade crystalline cellulose and represent a novel species of the genus Herbinix within the family Lachnospiraceae.

Herbivorax saccincola gen. nov., sp. nov., a cellulolytic, anaerobic, thermophilic bacterium isolated via in sacco enrichments from a lab-scale biogas reactor.

It is demonstrated that the isolate formed a hitherto unknown subline within the family Ruminococcaceae, and a novel genus and species, Herbivoraxsaccincola gen. nov, is proposed on the basis of phylogenetic analysis and physiological properties of the novel isolate.

Anaeropeptidivorans aminofermentans gen. nov., sp. nov., a mesophilic proteolytic salt-tolerant bacterium isolated from a laboratory-scale biogas fermenter, and emended description of Clostridium colinum

Based on physiological, chemotaxonomic and genetic data, the description of a novel species and genus Anaeropeptidivorans aminofermentans gen. nov., sp.

Anaerosacchariphilus polymeriproducens gen. nov., sp. nov., an anaerobic bacterium isolated from a salt field.

Based on the results of phylogenetic, physiologic and chemotaxonomic studies, Anaerosacchariphilus polymeriproducens gen. nov., sp.

Descriptions of Anaerotaenia torta gen. nov., sp. nov. and Anaerocolumna cellulosilytica gen. nov., sp. nov. isolated from a methanogenic reactor of cattle waste and reclassification of Clostridium aminovalericum, Clostridium jejuense and Clostridium xylanovorans as Anaerocolumna species.

Phenotypic and phylogenetic analyses suggested that these two isolates should be assigned to novel genera other than the genus Clostridium, and thus the genera Anaerotaenia gen. nov. and Anaerocolumna gen.nov.

Ruminiclostridium herbifermentans sp. nov., a mesophilic and moderately thermophilic cellulolytic and xylanolytic bacterium isolated from a lab-scale biogas fermenter fed with maize silage.

This strain represents a novel species in the genus Ruminiclostridium, family Oscillospiraceae, class Clostridia and can be clustered into one clade with other species of the genus JCM 39124T.

Hungateiclostridium mesophilum sp. nov., a mesophilic, cellulolytic and spore-forming bacterium isolated from a biogas fermenter fed with maize silage.

Comparative analysis of the almost-complete sequence of the 16S rRNA gene showed that the closest relatives of the novel anaerobic, mesophilic and cellulolytic bacterium were Hungateiclostridium straminisolvens CSK1T and Hungateilostridia thermocellum DSM 2360T.

Variimorphobacter saccharofermentans gen. nov., sp. nov., a new member of the family Lachnospiraceae, isolated from a maize-fed biogas fermenter.

The isolated strainMD1T can be considered as representing a novel genus in the family Lachnospiraceae, for which the name Variimorphobacter saccharofermentans gen. nov., sp.

Anaerosphaera multitolerans sp. nov., a salt-tolerant member of the family Peptoniphilaceae isolated from a mesophilically operated biogas fermenter fed with maize silage.

16S rRNA gene sequence comparisons indicated that the isolates had 100 % sequence identity and were most closely related to Anaerosphaera amininiphila WN036T, with which they shared a 16S r RNA gene sequence similarity of 93.1 %.

Anaerosporobacter mobilis gen. nov., sp. nov., isolated from forest soil.

On the basis of the polyphasic evidence, strain HY-37-4(T) represents a novel taxon, for which the name Anaerosporobacter mobilis gen. nov., sp.

Clostridium jejuense sp. nov., isolated from soil.

It is proposed that strain HY-35-12T represents a novel species, Clostridium jejuense sp.

Clostridium phytofermentans sp. nov., a cellulolytic mesophile from forest soil.

An obligately anaerobic, mesophilic, cellulolytic bacterium, strain ISDgT, was isolated from forest soil and is proposed as a novel species in the genus Clostridium, for which the name Clastridium phytofermentans sp.

Mobilitalea sibirica gen. nov., sp. nov., a halotolerant polysaccharide-degrading bacterium.

A novel strictly anaerobic, halotolerant, organotrophic bacterium, strain P3M-3(T), was isolated from a microbial mat formed under the flow of hot water emerging from a 2775 m-deep well in Tomsk

Characterization of a new xylanolytic bacterium, Clostridium xylanovorans sp. nov.

Clostridium herbivorans sp. nov., a cellulolytic anaerobe from the pig intestine.

A new cellulolytic anaerobic clostridium was isolated from the intestinal tract of pigs, a gram-positive, motile rod, formed terminal to subterminal swollen sporangia, and required a fermentable carbohydrate for growth.

Clostridium populeti sp. nov., a Cellulolytic Species from a Woody-Biomass Digestor

A new anaerobic, mesophilic, sporeforming, cellulolytic bacterium is described, which formed terminal oval spores which swelled the cells and stained gram negative, and was motile rod-shaped.

A genomic update on clostridial phylogeny: Gram-negative spore formers and other misplaced clostridia.

It is reaffirmed that 16S rRNA and ribosomal protein sequences are better indicators of evolutionary proximity than phenotypic traits, even such key ones as the structure of the cell envelope and Gram-staining pattern.

A study was made of gram-positive nonsporeforming strains isolated from the rumina of sheep fed corn stover with or without different amounts of corn grain. Two groups of xylanolytic,
