| propionispora vibrioides, nov. gen., nov. sp., a new gram-negative, spore-forming anaerobe that ferments sugar alcohols. | anaerobic enrichment cultures, with erythritol as substrate, resulted in the isolation of a strain with properties not yet found in an existing genus in this combination. the strain, fkbs1, was strictly anaerobic, stained gram-negative and formed spores. cells were small motile vibrios with flagella inserted at the concave side of the cell. spores were located terminally and caused only slight swelling of the cells if compared to related spore-forming genera. fkbs1 fermented fructose, mannitol, ... | 2000 | 11081792 |
| propionispora hippei sp. nov., a novel gram-negative, spore-forming anaerobe that produces propionic acid. | a gram-negative, spore-forming anaerobe, ks(t), was isolated from an enrichment culture that was set up for anaerobic degradation of the aliphatic polyester poly(propylene adipate). the strain had the cellular organization of sporomusa, vibrio-shaped cells and terminal round spores, and fermented sugars and sugar alcohols to propionic and acetic acid. based on the morphological and physiological features as well as on a 16s rrna gene similarity of 98 %, it was grouped with propionispora vibrioid ... | 2004 | 15143048 |
| biodegradation of aliphatic homopolyesters and aliphatic-aromatic copolyesters by anaerobic microorganisms. | the anaerobic degradability of natural and synthetic polyesters is investigated applying microbial consortia (3 sludges, 1 sediment) as well as individual strains isolated for this purpose. in contrast to aerobic conditions, the natural homopolyester polyhydroxybutyrate (phb) degrades faster than the copolyester poly(hydroxybutyrate-co-hydroxyvalerate) (phbv). for the synthetic polyester poly(epsilon-caroplacton) (pcl), microbial degradation in the absence of oxygen could be clearly demonstrated ... | 2004 | 15360276 |
| anaerospora hongkongensis gen. nov. sp. nov., a novel genus and species with ribosomal dna operon heterogeneity isolated from an intravenous drug abuser with pseudobacteremia. | a bacterium was isolated from the blood culture of an intravenous drug abuser with pseudobacteremia. the cells were strictly anaerobic, straight or slightly curved, sporulating, gram-negative rods. it grew on sheep blood agar as non-hemolytic, pinpoint colonies after 48 hr of incubation at 37 c in an anaerobic environment. it was motile but did not produce catalase or cytochrome oxidase. 16s ribosomal dna (rdna) sequencing revealed three different copies of 16s rdna sequences. more than 90% of t ... | 2005 | 15665451 |
| sporolituus thermophilus gen. nov., sp. nov., a citrate-fermenting thermophilic anaerobic bacterium from geothermal waters of the great artesian basin of australia. | a strictly anaerobic, sluggishly motile, spore-forming, thermophilic bacterium, designated strain aeg(t), was isolated from microbial mats colonizing a runoff channel formed by free-flowing thermal waters of a bore well (new lorne bore; registered number 17263) in the great artesian basin, australia. cells of strain aeg(t) were curved rods (2.0-10.0x0.8-1.0 mum) and stained gram-negative. the strain grew optimally in tryptone-yeast extract-citrate medium at 55 degrees c (range for growth between ... | 2009 | 19628612 |
