Genomic Analysis of Rhodococcus sp. Br-6, a Bromate Reducing Bacterium Isolated From Soil in Chiba, Japan.

ABSTRACT: Bromate is a byproduct of the ozone disinfection of drinking water. It is a genotoxic carcinogen and causes renal cell tumors in rats. Physicochemical removal of bromate is very difficult, making microbial reduction of bromate to bromide a promising approach to eliminate bromate from water. Rhodococcus sp. Br-6, isolated from soil, can efficiently reduce bromate by using acetate as an electron donor. We determined the draft genome sequence of Rhodococcus sp. Br-6 for the potential practical application of the bromate-reducing bacterium. Core genome phylogeny suggests that the Br-6 strain is most closely related to R. equi. The Br-6 genome contains genes encoding multiple isoforms of diaphorase, previously found to be involved in Br-6-mediated bromate reduction. The genes identified in the present study could be effective targets for experimental studies of microbial bromate reduction in the future.

Rhodococcus daqingensis sp. nov., isolated from petroleum-contaminated soil.

Project description:A novel Gram-stain positive, aerobic, non-motile bacterial strain, designated Z1T, was isolated from a sample of petroleum-contaminated soil collected in Daqing, Heilongjiang province, China and characterised with a series of taxonomic approaches. The morphological and chemotaxonomic properties of the isolate were typical of those of members of the genus Rhodococcus. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Z1T belongs to the genus Rhodococcus and clustered with Rhodococcus maanshanensis DSM 44675T (99.2%, sequence similarity) and Rhodococcus tukisamuensis JCM 11308T (97.9%), respectively. However, the DNA-DNA hybridizations between strain Z1T and R. maanshanensis DSM 44675T and R. tukisamuensis JCM 11308T were both less than 70%. The optimal growth temperature and pH for strain Z1T were found to be at 28 °C and at pH 7.0. The peptidoglycan was found to contain meso-diaminopimelic acid; arabinose, galactose and glucose were detected as diagnostic sugars. The main polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified lipid; MK-8(H2) was found as the major menaquinone. The major fatty acids were identified as C16:0, 10-methyl C18:0 and C18:1ω9c. Mycolic acids were found to be present. The G + C content of the genomic DNA was determined to be 66.7 mol%. Based on a comparative analysis of phenotypic and genotypic characteristics, in combination with DNA-DNA hybridization results, strain Z1T can be distinguished from the type strains of its two close neighbours as a novel species of the genus Rhodococcus, for which the name Rhodococcus daqingensis sp. nov. is proposed. The type strain is Z1T (= CGMCC 1.13630T = DSM 107227T).

Bradyrhizobium ganzhouense sp. nov., an effective symbiotic bacterium isolated from Acacia melanoxylon R. Br. nodules.

Project description:Three slow-growing rhizobial strains, designated RITF806(T), RITF807 and RITF211, isolated from root nodules of Acacia melanoxylon grown in Ganzhou city, Jiangxi Province, China, had been previously defined, based on amplified 16S rRNA gene restriction analysis, as a novel group within the genus Bradyrhizobium. To clarify their taxonomic position, these strains were further analysed and compared with reference strains of related bacteria using a polyphasic approach. According to 16S rRNA gene sequence analysis, the isolates formed a group that was closely related to 'Bradyrhizobium rifense' CTAW71, with a similarity value of 99.9%. In phylogenetic analyses of the housekeeping and symbiotic gene sequences, the three strains formed a distinct lineage within the genus Bradyrhizobium, which was consistent with the results of DNA-DNA hybridization. In analyses of cellular fatty acids and phenotypic features, some differences were found between the novel group and related species of the genus Bradyrhizobium, indicating that these three strains constituted a novel group distinct from any recognized species of the genus Bradyrhizobium. Based on the data obtained in this study, we conclude that our strains represent a novel species of the genus Bradyrhizobium, for which the name Bradyrhizobium ganzhouense sp. nov. is proposed, with RITF806(T) ( = CCBAU 101088(T) = JCM 19881(T)) as the type strain. The DNA G+C content of strain RITF806(T) is 64.6 mol% (T(m)).

Sphingobacterium pedocola sp. nov. a novel halotolerant bacterium isolated from agricultural soil.

Project description:A Gram-reaction-negative halotolerant bacterial strain, designated Ka21T, was isolated from agricultural soil and characterised using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, highest similarity was found with Sphingobacterium alkalisoli Y3L14T (96.72%). Cells were observed to be aerobic, non-motile rods. The isolate was found to be able to grow between 0 and 10% of NaCl concentration. The assembled genome of strain Ka21T has a total length of 5.2 Mb with a G + C content of 41.0 mol%. According to the genome analysis, Ka21T encodes several glycoside hydrolases that may play a role in the degradation of accumulated plant biomass in the soil. Based on phenotypic characteristics and phylogenetic analysis, it is concluded that strain Ka21T represents a novel species in the Sphingobacterium genus for which the name Sphingobacterium pedocola sp. nov. is proposed. The type strain of the species is strain Ka21T (= LMG 31575T = NCAIM B.02636T).

Bacteroides sp. strain D8, the first cholesterol-reducing bacterium isolated from human feces.

Project description:The microbial community in the human colon contains bacteria that reduce cholesterol to coprostanol, but the species responsible for this conversion are still unknown. We describe here the first isolation and characterization of a cholesterol-reducing bacterium of human intestinal origin. Strain D8 was isolated from a 10(-8) dilution of a fresh stool sample provided by a senior male volunteer with a high capacity to reduce luminal cholesterol to coprostanol. Cholesterol-to-coprostanol conversion by strain D8 started on the third day, while cells were in stationary phase, and was almost complete after 7 days. Intermediate products (4-cholesten-3-one and coprostanone) were occasionally observed, suggesting an indirect pathway for cholesterol-to-coprostanol conversion. Resting-cell assays showed that strain D8 could reduce 1.5 mumol of cholesterol/mg bacterial protein/h. Strain D8 was a gram-negative, non-spore-forming, rod-shaped organism identified as a member of the genus Bacteroides closely related to Bacteroides vulgatus, based on its morphological and biochemical characteristics. The 16S rRNA gene sequence of strain D8 was most similar (>99.5%) to those of two isolates of the recently described species Bacteroides dorei. Phylogenetic tree construction confirmed that Bacteroides sp. strain D8 clustered within an independent clade together with these B. dorei strains. Nevertheless, no cholesterol-reducing activity could be detected in cultures of the B. dorei type strain. Based on Bacteroides group-specific PCR-temporal temperature gradient gel electrophoresis, there was no correlation between the presence of a band comigrating with the band of Bacteroides sp. strain D8 and cholesterol conversion in 11 human fecal samples, indicating that this strain is unlikely to be mainly responsible for cholesterol conversion in the human population.

Flavobacterium hungaricum sp. nov. a novel soil inhabitant, cellulolytic bacterium isolated from plough field.

Project description:A Gram-negative bacterial strain, named Kb82, was isolated from agricultural soil and a polyphasic approach was used for characterisation and to determine its taxonomic position. Based on 16S rRNA gene sequence analysis, the highest similarity was found with Flavobacterium artemisiae SYP-B1015 (98.2%). The highest ANI (83.3%) and dDDH (26.5%) values were found with Flavobacterium ginsenosidimutans THG 01 and Flavobacterium fluviale HYN0086T, respectively. The isolate is aerobic with rod-shaped cells, positive for catalase and negative for oxidase tests. The DNA G+C content is 34.7 mol%. The only isoprenoid quinone is menaquinone 6 (MK-6). The major fatty acids are iso-C15:0, summed feature 3 (C16:1 ω7c/C16:1 ω6c) and iso-C17:0 3OH. The major polar lipid is phosphatidylethanolamine. On the bases of phenotypic characteristics and analysis of 16S rRNA gene sequences, it is concluded that strain Kb82T represents a novel species in the Flavobacterium genus, for which the name Flavobacterium hungaricum sp. nov. is proposed. The type strain of the species is strain Kb82T (= LMG 31576T = NCAIM B.02635T).
