Abstract A novel strictly anaerobic, cellobiose-degrading bacterium, strain Cello, was isolated from a human faecal sample by combining enrichments in liquid and soft-agar basal media. A noteworthy characteristic was its inability to grow on normal agar plates and in roll tubes. The cells were coccus shaped and non-motile, with an extracellular slime layer. Growth of strain Cello T occurred between 20 and 40 degreesC, with optimal growth at 37 degreesC. The pH range for growth was 5-7-5 with an optimum at 6-5. In pure culture, strain Cello T could only grow on a variety of sugars. Glucose was converted to acetate, ethanol and H-2. The doubling time on glucose was 0.5 h. In a syntrophic co-culture with Methanospirillum hungatei strain JF-1(T), strain Cello(T) converted glucose to acetate and H-2. The G+C content was 59.2 mol%. 16S rDNA analysis revealed that the closest relatives of strain Cello(T) were two uncultured bacteria from anaerobic digesters, both with 94% 16S rDNA sequence similarity. The closest cultured representatives belong to genera of the bacterial division 'Verrucomicrobia'. The name Victivallis vadensis gen. nov., sp. nov. is proposed for strain Cello(T) (=DSM 14823(T) =ATCC BAA-548(T)).
