| biodiversity of polycyclic aromatic hydrocarbon-degrading bacteria from deep sea sediments of the middle atlantic ridge. | the bacteria involved in the biodegradation of polycyclic aromatic hydrocarbons (pahs) in deep sea subsurface environments are largely unknown. in order to reveal their biodiversity, sediments from 2.2 m under the bottom surface at a water depth of 3542 m were sampled on the middle atlantic ridge with a gravity column sampler. the sediments were promptly enriched with either crude oil or a mixture of pahs (naphthalene, phenanthrene and pyrene) as the sole carbon source, and further enriched with ... | 2008 | 18445026 |
| [predominant strains of polycyclic aromatic hydrocarbon-degrading consortia from deep sea of the middle atlantic ridge]. | in order to identify the predominant strains of polycyclic aromatic hydrocarbon (pah)-degrading consortia harboring in sea water and surface sediment collected from deep sea of the middle atlantic ridge. | 2009 | 19873754 |
| gene diversity of cyp153a and alkb alkane hydroxylases in oil-degrading bacteria isolated from the atlantic ocean. | alkane hydroxylases, including the integral-membrane non-haem iron monooxygenase (alkb) and cytochrome p450 cyp153 family, are key enzymes in bacterial alkane oxidation. although both genes have been detected in a number of bacteria and environments, knowledge about the diversity of these genes in marine alkane-degrading bacteria is still limited, especially in pelagic areas. in this report, 177 bacterial isolates, comprising 43 genera, were obtained from 18 oil-degrading consortia enriched from ... | 2010 | 20148932 |
| isolation and characterization of phenanthrene-degrading strains sphingomonas sp. zp1 and tistrella sp. zp5. | two bacteria strains sphingomonas sp. strain zp1 and tistrella sp. strain zp5 were identified as phenanthrene-degrading ones, based on gram staining, oxydase reaction, biochemical tests, fame analysis, g+c content and 16s rdna gene sequence analysis. we isolated these two bacteria strains sphingomonas sp. zp1 and tistrella sp. zp5 from soil samples contaminated with polycyclic aromatic hydrocarbon (pah)-containing waste from oil refinery field in shanghai, china. strain sphingomonas sp. zp1 was ... | 2008 | 17850962 |
| geminicoccus roseus gen. nov., sp. nov., an aerobic phototrophic alphaproteobacterium isolated from a marine aquaculture biofilter. | a gram-negative, strictly aerobic, diplococcoid bacterium (strain d2-3(t)) was isolated from the biofilter of a recirculating marine aquaculture system. phylogenetic analysis of the 16s rrna gene sequence of d2-3(t) indicated that the new organism occupied a novel lineage within the alpha-1 subclass of proteobacteria and was related to the genera rhodothalassium, azospirillum, craurococcus, acidiphilium, and tistrella. the highest sequence similarity (90.8%) of the 16s rrna gene sequence of d2-3 ... | 2007 | 17643894 |
| tistrella mobilis gen nov, sp nov, a novel polyhydroxyalkanoate-producing bacterium belonging to alpha-proteobacteria. | strain iam 14872, isolated from wastewater in thailand, is capable of producing polyhydroxyalkanoate. this bacterium is gram-negative, rod-shaped, strictly aerobic and highly motile with a single polar flagellum. both oxidase and catalase activities are positive. the g+c content of dna is 67.5% and q-10 is the major quinone. the major cellular fatty acids are c(18:1)omega7c, 2-oh c(18:0) and 3-oh c(14:0). on the basis of the 16s rdna sequence analysis and phenotypic properties, it is proposed th ... | 2002 | 12682872 |
| Bacterial production of the tunicate-derived antitumor cyclic depsipeptide didemnin B. | Natural products obtained from marine invertebrates such as sponges and tunicates are attractive sources of drugs. However, a critical obstacle in the development of these compounds is the problem of supply. In most cases, neither chemical synthesis nor mariculture of invertebrates is economically feasible. Due to structural similarities, many marine natural products are suspected to be produced by associated microorganisms. A favorable strategy for the production of such compounds is to use cul ... | 2011 | 22035372 |
| tistrella bauzanensis sp. nov., a novel bacterium isolated from soil. | a gram-negative, strictly aerobic, motile and rod-shaped bacterium (bz78(t)), was isolated from soil from an industrial site. phylogenetic analysis based on 16s rrna gene sequences showed that strain bz78(t) belonged to the family rhodospirillaceae and formed a coherent cluster with type strain of tistrella mobilis (98.3 % 16s rrna gene pairwise similarity). the predominant cellular fatty acids of strain bz78(t) were c(18:1)ω7c (58.3 %), c(19:0) cyclo ω8c (11.5 %), c(18:12)-oh (10.9 %) and c(14: ... | 2010 | 20952545 |
