| methanobacterium beijingense sp. nov., a novel methanogen isolated from anaerobic digesters. | two methanogenic strains, 8-2t and 4-1, with rod-shaped (0.4-0.5 x 3-5 microm), non-motile cells, sometimes observed in chains, were isolated from two anaerobic digesters in beijing, china. the two strains used h2/co2 and formate for growth and produced methane. the temperature range for growth was 25-50 degrees c, with fastest growth at 37 degrees c. the ph ranges for growth and methane production were 6.5-8.0 for strain 8-2t and 6.8-8.6 for strain 4-1, with the fastest growth at ph 7.2 for str ... | 2005 | 15653895 |
