| description of pelomonas aquatica sp. nov. and pelomonas puraquae sp. nov., isolated from industrial and haemodialysis water. | three gram-negative, rod-shaped, non-spore-forming bacteria (strains ccug 52769t, ccug 52770 and ccug 52771) isolated from haemodialysis water were characterized taxonomically, together with five strains isolated from industrial waters (ccug 52428, ccug 52507, ccug 52575t, ccug 52590 and ccug 52631). phylogenetic analysis based on 16s rrna gene sequences indicated that these isolates belonged to the class betaproteobacteria and were related to the genus pelomonas, with 16s rrna gene sequence sim ... | 2007 | 17978231 |
| field-based and laboratory stable isotope probing surveys of the identities of both aerobic and anaerobic benzene-metabolizing microorganisms in freshwater sediment. | laboratory incubations of coal-tar waste-contaminated sediment microbial communities under relatively controlled physiological conditions were used to interpret results of a field-based stable isotope probing (sip) assay. biodegradation activity of 13c-benzene was examined by gc/ms determination of net 13co2 production and by gc headspace analysis of benzene loss. key experimental variables were: the site of the assays (laboratory serum-bottle incubations and in situ field sediments), benzene co ... | 2008 | 18430012 |
| microbial diversity of traditional vietnamese alcohol fermentation starters (banh men) as determined by pcr-mediated dgge. | the diversity of fungi and bacteria associated with traditional vietnamese alcohol fermentation starters (banh men) was investigated by pcr-mediated dgge. from 52 starter samples, 13 species of fungi (including yeasts) and 23 species of bacteria were identified. the fungal composition of the starters was consistent with little variation among samples. it consisted of amylase producers (rhizopus oryzae, r. microsporus, absidia corymbifera, amylomyces sp., saccharomycopsis fibuligera), ethanol pro ... | 2008 | 18838186 |
| inhella inkyongensis gen. nov., sp. nov., a new freshwater bacterium in the order burkholderiales. | a freshwater bacterium, designated imcc1713(t), was isolated from a highly eutrophic artificial pond. cells of the strain were gram-negative, chemoheterotrophic, polybeat and obligately aerobic short rods that were motile with a single polar flagellum. the 16s rrna gene sequence similarity analysis showed that the novel strain was most closely related to the species roseateles depolymerans (96.3%), mitsuaria chitosanitabida (96.2%), ideonella dechloratans (96.2%), and pelomonas saccharophila (96 ... | 2009 | 19190402 |
| kinneretia asaccharophila gen. nov., sp. nov., isolated from a freshwater lake, a member of the rubrivivax branch of the family comamonadaceae. | a strictly aerobic, gram-negative bacterium, strain kin192(t), isolated from fresh water from lake kinneret, israel, was examined using a polyphasic approach to characterize and clarify its phylogenetic and taxonomic position. sequences of the 16s rrna and gyrb genes and its1 revealed close relationships to species of the genera pelomonas, mitsuaria and roseateles, in the rubrivivax branch of the family comamonadaceae of the betaproteobacteria. physiological and biochemical tests, cellular fatty ... | 2010 | 19661516 |
| endophytic bacterial diversity in roots of typha angustifolia l. in the constructed beijing cuihu wetland (china). | we investigated the community structure of endophytic bacteria in narrowleaf cattail (typha angustifolia l.) roots growing in the beijing cuihu wetland, china, using the 16s rdna library technique. in total, 184 individual sequences were used to assess the diversity of endophytic bacteria. phylogenetic analysis revealed that 161 clones (87.5%) were affiliated with proteobacteria, other clones grouped into cytophaga/flexibacter/bacteroids (3.3%), fusobacteria (3.8%), and nearly 5% were uncultured ... | 2010 | 21111814 |
| relationship between bacterial diversity and function under biotic control: the soil pesticide degraders as a case study. | in soil, the way biotic parameters impact the relationship between bacterial diversity and function is still unknown. to understand these interactions better, we used rna-based stable-isotope probing to study the diversity of active atrazine-degrading bacteria in relation to atrazine degradation and to explore the impact of earthworm-soil engineering with respect to this relationship. bulk soil, burrow linings and earthworm casts were incubated with (13)c-atrazine. the pollutant degradation was ... | 2010 | 21160539 |
| expressed nifh genes of endophytic bacteria detected in field-grown sweet potatoes (ipomoea batatas l.). | we examined the nitrogenase reductase (nifh) genes of endophytic diazotrophic bacteria expressed in field-grown sweet potatoes (ipomoea batatas l.) by reverse transcription (rt)-pcr. gene fragments corresponding to nifh were amplified from mrna obtained from the stems and storage roots of field-grown sweet potatoes several months after planting. sequence analysis revealed that these clones were homologous to the nifh sequences of bradyrhizobium, pelomonas, and bacillus sp. in the dna database. i ... | 2008 | 21558693 |
| five-week dietary exposure to dry diets alters the faecal bacterial populations in the domestic cat (felis catus). | the effects of wet (canned) or dry (kibbled) diets on faecal bacterial populations in the cat were investigated in eight domestic short-haired cats (four males and four females; averaging 6 years of age and 3.4 kg) in a nested design. the cats were fed ad libitum a commercially available wet diet (moisture 82.0 %, crude protein 51.7 %, fat 28.9 %, carbohydrate (cho) 8.9 % and ash 10.6 % dm) for 5 weeks. on the fifth week, individual feed intakes and faecal outputs were determined. fresh faecal s ... | 2011 | 22005435 |
