| isoprenoid biosynthesis in bacteria: a novel pathway for the early steps leading to isopentenyl diphosphate. | incorporation of 13c-labelled glucose, acetate, pyruvate or erythrose allowed the determination of the origin of the carbon atoms of triterpenoids of the hopane series and/or of the ubiquinones from several bacteria (zymomonas mobilis, methylobacterium fujisawaense, escherichia coli and alicyclobacillus acidoterrestris) confirmed our earlier results obtained by incorporation of 13c-labelled acetate into the hopanoids of other bacteria and led to the identification of a novel biosynthetic route f ... | 1993 | 8240251 |
| methylobacterium hispanicum sp. nov. and methylobacterium aquaticum sp. nov., isolated from drinking water. | members of the genus methylobacterium are ubiquitous in nature and can be isolated from almost any freshwater environment where dissolved oxygen exists. this genus is composed of a variety of pink-pigmented, facultatively methylotrophic (ppfm) bacteria. during a screening programme to monitor the bacterial population present in the drinking water of a municipal water supply in seville (spain) during the year 2003, five strains of ppfm bacteria were isolated and characterized. analysis of their c ... | 2005 | 15653888 |
| regulation of ethylene levels in canola (brassica campestris) by 1-aminocyclopropane-1-carboxylate deaminase-containing methylobacterium fujisawaense. | we report the presence of acc deaminase in methylobacterium fujisawaense and its lowering of ethylene levels and promotion of root elongation in canola seedlings under gnotobiotic conditions. to test a part of the previous model proposed for acc deaminase producing bacteria with methylobacterium, acc levels and various enzyme activities were monitored in canola. lower amounts of acc were present in the tissues of seeds treated with m. fujisawaense strains than in control seeds treated with mgso( ... | 2006 | 16416316 |
| methylobacterium oryzae sp. nov., an aerobic, pink-pigmented, facultatively methylotrophic, 1-aminocyclopropane-1-carboxylate deaminase-producing bacterium isolated from rice. | a pink-pigmented, facultatively methylotrophic bacterium, strain cbmb20t, isolated from stem tissues of rice, was analysed by a polyphasic approach. strain cbmb20t utilized 1-aminocyclopropane 1-carboxylate (acc) as a nitrogen source and produced acc deaminase. it was related phylogenetically to members of the genus methylobacterium. 16s rrna gene sequence analysis indicated that strain cbmb20t was most closely related to methylobacterium fujisawaense, methylobacterium radiotolerans and methylob ... | 2007 | 17267973 |
| methylobacterium iners sp. nov. and methylobacterium aerolatum sp. nov., isolated from air samples in korea. | two bacterial strains isolated from air samples, 5317s-33(t) and 5413s-11(t), were characterized by determining their phenotypic characteristics, cellular fatty acid profiles and phylogenetic positions based on 16s rrna gene sequence analysis. 16s rrna gene sequence analysis showed that these isolates belonged to the genus methylobacterium. strain 5317s-33(t) was most closely related to methylobacterium adhaesivum ar27(t) (97.9% sequence similarity). strain 5413s-11(t) was most closely related t ... | 2008 | 18175690 |
| culture-independent assessment of rhizobiales-related alphaproteobacteria and the diversity of methylobacterium in the rhizosphere and rhizoplane of transgenic eucalyptus. | the rhizosphere is an ecosystem exploited by a variety of organisms involved in plant health and environmental sustainability. abiotic factors influence microorganism-plant interactions, but the microbial community is also affected by expression of heterologous genes from host plants. in the present work, we assessed the community shifts of alphaproteobacteria phylogenetically related to the rhizobiales order (rhizobiales-like community) in rhizoplane and rhizosphere soils of wild-type and trans ... | 2009 | 18536862 |
| methylobacterium phyllosphaerae sp. nov., a pink-pigmented, facultative methylotroph from the phyllosphere of rice. | a pink-pigmented, aerobic, facultatively methylotrophic bacterial strain, cbmb27t, isolated from leaf tissues of rice (oryza sativa l. 'dong-jin'), was analysed using a polyphasic taxonomic approach. comparative 16s rrna gene sequence-based phylogenetic analysis placed the strain in a clade with the species methylobacterium oryzae, methylobacterium fujisawaense and methylobacterium mesophilicum; strain cbmb27t showed sequence similarities of 98.3, 98.5 and 97.3 %, respectively, to the type strai ... | 2009 | 19126717 |
| thiosulfate oxidation and mixotrophic growth of methylobacterium goesingense and methylobacterium fujisawaense. | the mixotrophic growth with methanol plus thiosulfate was examined in nutrient-limited mixotrophic condition for methylobacterium goesingense cbmb5 and methylobacterium fujisawaense cbmb37. thiosulfate oxidation increased the growth and protein yield in mixotrophic medium that contained 150 mm methanol and 20 mm sodium thiosulfate, at 144 h. respirometric study revealed that thiosulfate was the most preferable reduced inorganic sulfur source, followed by sulfite and sulfur. m. goesingense cbmb5 ... | 2009 | 19190404 |
| biodegradation of haloacetic acids by bacterial isolates and enrichment cultures from drinking water systems. | biodegradation is a potentially important loss process for haloacetic acids (haas), a class of chlorination byproducts, in water treatment and distribution systems, but little is known about the organisms involved (i.e., identity, substrate range, biodegradation kinetics). in this research, 10 biomass samples (i.e., tap water, distribution system biofilms, and prechlorinated granular activated carbon filters) from nine drinking water systems were used to inoculate a total of thirty enrichment cu ... | 2009 | 19534130 |
| unusual methylobacterium fujisawaense infection in a patient with acute leukaemia undergoing hematopoietic stem cell transplantation: first case report. | microorganisms of the genus methylobacterium are facultative methylotrophic, gram-negative rods that are ubiquitous in nature and rarely cause human disease, mostly in subjects with preexisting causes of immune depression. methylobacterium fujisawaense, first proposed as a new species in 1988, has never been reported as a bacterial agent of human infections so far. here we describe a case of m. fujisawaense infection in a relapsed acute leukaemia undergoing unrelated allogeneic hematopoietic ste ... | 2010 | 20396386 |
| methylobacterium marchantiae sp. nov., a pink-pigmented, facultatively methylotrophic bacterium isolated from the thallus of a liverwort. | a pink-pigmented, facultatively methylotrophic bacterium, designated strain jt1(t), was isolated from a thallus of the liverwort marchantia polymorpha l. and was analysed by using a polyphasic approach. comparative 16s rrna gene sequence analysis placed the strain in a clade with methylobacterium adhaesivum ar27(t), methylobacterium fujisawaense dsm 5686(t), methylobacterium radiotolerans jcm 2831(t) and methylobacterium jeotgali s2r03-9(t), with which it showed sequence similarities of 97.8, 97 ... | 2011 | 20495043 |
| rice seeds as sources of endophytic bacteria. | endophytic bacteria are considered to originate from the external environment. to examine the hypothesis that rice (oryza sativa, cultivar kinuhikari) seeds are a source of endophytic bacteria, we isolated endophytic bacteria from the shoots, remains of the seeds, and roots of rice seedlings that were aseptically cultivated in vitro from surface-disinfected seeds. of the various bacterial strains isolated, the closest relatives, identified by 16s rrna gene sequencing, were: bacillus firmus, b. f ... | 2009 | 21566368 |
| aggregation of selected plant growth promoting methylobacterium strains: role of cell surface components and hydrophobicity. | the bacterial cell surface plays a major role in the bacterial aggregation that in turn plays a positive role in affecting the bacterial dispersion and survival in soil and their ability to adhere to plant surfaces. plant growth-promoting methylobacterium strains, methylobacterium goesingense cbmb5, methylobacterium sp. cbmb12, methylobacterium oryzae cbmb20, methylobacterium fujisawaense cbmb37, m. oryzae cbmb110 and methylobacterium suomiense cbmb120 were evaluated for aggregation efficiency. ... | 2013 | 23354325 |
