| novel halophilic aerobic anoxygenic phototrophs from a canadian hypersaline spring system. | the first enumeration of cultivable obligately aerobic phototrophic bacteria from a terrestrial saline spring was accomplished in the east german creek system (salinity approximately 6%), near lake winnipegosis, manitoba, canada. occurring at densities up to 3.3x10(7) cfu/ml of sample, aerobic phototrophs comprised 15-36% of the total cultivable bacterial population in the diatom- and chlorophyte-dominated aerobic microbial mats. many of the representative strains isolated for phenotypic charact ... | 2008 | 18385928 |
| chromocurvus halotolerans gen. nov., sp. nov., a gammaproteobacterial obligately aerobic anoxygenic phototroph, isolated from a canadian hypersaline spring. | a strain eg19(t) of aerobic bacteria able to form pleomorphic cells was isolated from a brine spring runoff stream in the west central region of the province of manitoba, canada. the pale pinkish purple strain contained bacteriochlorophyll a incorporated into light-harvesting i and reaction center complexes. its inability to grow under anaerobic illuminated conditions prompted designation as a member of the functional group known as aerobic anoxygenic phototrophic bacteria. phylogenetic analysis ... | 2011 | 21479531 |
