| petrimonas sulfuriphila gen. nov., sp. nov., a mesophilic fermentative bacterium isolated from a biodegraded oil reservoir. | a mesophilic, anaerobic, fermentative bacterium, strain bn3(t), was isolated from a producing well of a biodegraded oil reservoir in canada. cells were gram-negative, non-motile rods that did not form spores. the temperature range for growth was 15-40 degrees c, with optimum growth at 37-40 degrees c. the strain grew with up 4 % nacl, with optimum growth in the absence of nacl. tryptone was required for growth. yeast extract and elemental sulfur stimulated growth. growth was also enhanced during ... | 2005 | 15879242 |
| unexpected stability of bacteroidetes and firmicutes communities in laboratory biogas reactors fed with different defined substrates. | in the present study, bacterial communities in 200 l biogas reactors containing liquid manure consecutively fed with casein, starch and cream were investigated over a period of up to 33 days. a 16s rrna gene clone library identified bacteroidetes and firmicutes with 58.9 % and 30.1 %, respectively, as most abundant bacterial groups in the starting material. community development of both groups was monitored by real-time pcr and single strand conformation polymorphism (sscp) analysis. the firmicu ... | 2012 | 22247168 |
