sphingomonas astaxanthinifaciens sp. nov., a novel astaxanthin-producing bacterium of the family sphingomonadaceae isolated from misasa, tottori, japan. | a red-pigmented, gram-negative, motile, strictly aerobic, mesophilic, oval- or short rod-shaped bacterium (tdma-17(t)) was isolated from fresh water collected at misasa, a radioactive site in japan. tdma-17(t) was slightly tolerant against gamma-ray irradiation, and effectively produced carotenoids (2.8 mg g(-1) dry cells) including, astaxanthin and astaxanthin isomers. phylogenetic analysis based on 16s rrna gene sequences placed tdma-17(t) in a distinct lineage in the family sphingomonadaceae, ... | 2007 | 17590230 |
sphingomonas jaspsi sp. nov., a novel carotenoid-producing bacterium isolated from misasa, tottori, japan. | a yellow-pigmented, gram-negative, motile, strictly aerobic, pleomorphic bacterium (strain tdma-16(t)) was isolated from a freshwater sample collected at misasa (tottori, japan). strain tdma-16(t) was slightly tolerant to gamma-ray irradiation and produced carotenoids, including zeaxanthin, nostoxanthin and an unknown carotenoid, effectively [1.7 mg (g dry cells)(-1)]. the dna g+c content of strain tdma-16(t) was 63.3 mol%. phylogenetic analysis based on 16s rrna gene sequences placed strain tdm ... | 2007 | 17625171 |
unique diversity of carotenoid-producing bacteria isolated from misasa, a radioactive site in japan. | we obtained carotenoid-producing microorganisms at a high frequency from water samples collected at misasa (tottori, japan), a region known for its high natural radioactivity content. a comprehensive 16s rrna gene-based phylogenetic analysis revealed that the 104 potential carotenoid producers isolated from misasa could be classified into 38 different species belonging to seven bacterial classes (flavobacteria, sphingobacteria, alpha-proteobacteria, gamma-proteobacteria, deinococci, actinobacter ... | 2007 | 17828533 |
