SILICIBACTER LACUSCAERULENSIS
| Class: | Alpha Proteobacteria |
| Genus: | Silicibacter |
| Species: | Silicibacter lacuscaerulensis |
| Description: | Silicibacter lacuscaerulensis, also known as Ruegeria lacuscaerulensis, is a mesophilic moderately halophilic bacterium. This organism can grow at temperatures of up to 50 0C.Mesophilic, moderately halophilic bacteria were isolated from a silica-rich geothermal lake, the Blue Lagoon in Iceland. The isolates are strictly aerobic, but reduce nitrate to nitrite, and are oxidase- and catalase-positive. The nonsporeforming and nonmotile Gram negative rods are 0.6-0.8 microm in diameter and variable in length (9-18 microm), and contain gas vacuoles. The minimum, optimum, and maximum temperatures for growth are 22 degrees C, 45 degrees C, and 50 degrees C, respectively. The isolates do not grow without added salt in the medium and can grow at up to 7% NaCl (w/v). The optimal salinity for growth is 3.5%-4% NaCl. The pH range for growth is 6.5-8.5, with the optimal pH at 7.0. |
