| sphingomonas phyllosphaerae sp. nov., from the phyllosphere of acacia caven in argentina. | two bacterial strains (fa1 and fa2(t)) were isolated from the phyllosphere of a leguminous tree, acacia caven, in central argentina. the strains were gram-negative, strictly aerobic, rod-shaped, motile and formed yellow-pigmented colonies on nutrient agar. the two-primer rapd patterns of the two strains were identical, suggesting that they belong to the same species. the complete 16s rrna gene sequences of the two strains were obtained and comparisons demonstrated that they cluster phylogenetica ... | 2004 | 15545449 |
| sphingomonas yunnanensis sp. nov., a novel gram-negative bacterium from a contaminated plate. | a gram-negative bacterium, yim 003t, which was isolated from a contaminated plate in the laboratory, was subjected to a polyphasic taxonomic study. the organism had short-rod-shaped, motile cells, formed yellow-pigmented colonies on isp2 medium and its optimum growth ph was 7.0-7.5. the major respiratory lipoquinone was ubiquinone q-10. the phosphate-containing lipids detected in strain yim 003t were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, sph ... | 2005 | 16280497 |
| sphingomonas endophytica sp. nov., a novel bacterium isolated from artemisia annua l. | a novel bacterium (strain yim 65583(t)) belonging to the genus sphingomonas was isolated from a surface-sterilized tissue of artemisia annua l., which was collected from yunnan province, south-west china. its morphology, physiology, biochemical features were consistent with those members of the genus sphingomonas. 16s rrna gene sequence of strain yim 65583(t) further confirmed that it should be classified as a member of the genus sphingomonas and was most closely related to sphingomonas phyllosp ... | 2011 | 21873515 |
| taxonomic characterization and the bio-potential of bacteria isolated from glacier ice cores in the high arctic. | glacier ice and firn cores have ecological and biotechnological importance. the present study is aimed at characterizing bacteria in crustal ice cores from svalbard, the arctic. counts of viable isolates ranged from 10 to 7000 cfu/ml (mean 803 cfu/ml) while the total bacterial numbers ranged from 7.20 × 10(4) to 2.59 × 10(7) cells ml(-1) (mean 3.12 × 10(6) cells ml(-1) ). based on 16s rdna sequence data, the identified species belonged to seven species, namely bacillus barbaricus, pseudomonas ... | 2016 | 26567474 |
| sphingomonas metalli sp. nov., isolated from an abandoned lead-zinc mine. | a gram-stain-negative and non-motile bacterial strain designated 9o-5t was isolated from an abandoned lead-zinc mine in meizhou, guangdong province, southern china. the isolate was orange-pigmented, aerobic, and oxidase- and catalase-positive. phylogenetic analyses based on 16s rrna gene sequences indicated that strain 9o-5t belongs to the genus sphingomonas and was closely related to sphingomonas abaci dsm 15867t (97.6 % similarity), sphingomonas phyllosphaerae fa2t (96.9 %) and shingomonas gua ... | 2016 | 26908362 |
| identification of newly zeaxanthin-producing bacteria isolated from sponges in the gulf of thailand and their zeaxanthin production. | sponge-associated bacteria have been found to produce a variety of bioactive compounds including natural pigments. here, we report the molecular identification of zeaxanthin-producing sponge-associated bacteria isolated from sponges in the gulf of thailand and the effect of environmental factors on zeaxanthin production from a bacterium. three colorful sponge-associated bacteria (chob06-6, koda19-6, and makb08-4) were identified based on the 16s rdna profile. the 16s rdna sequence-based analyses ... | 2012 | 22715027 |
