methylobrevis pamukkalensis gen. nov., sp. nov., a halotolerant restricted facultative methylotroph isolated from saline aerobic halotolerant restricted facultatively methylotrophic bacterium was isolated from a saline hot spring in pamukkale, turkey, and designated strain pk2(t). the cells of this strain were gram-stain-negative, asporogenous, motile short rods multiplying by binary fission. they utilized methanol, methylamine and mannitol as carbon and energy sources. the organism grew optimally at 30 °c in media containing 85 mm nacl and at ph 7.5-8.0. c1 compounds were assimilated via the isocitrate-lyase-p ...201525667389
mesorhizobium gobiense sp. nov. and mesorhizobium tarimense sp. nov., isolated from wild legumes growing in desert soils of xinjiang, china.twenty-four mesorhizobium strains were isolated from desert soils in the xinjiang region of china and were characterized by a polyphasic approach. these strains grouped into three clusters in igs-rflp, sds-page analysis of whole-cell proteins and box-pcr analysis, corresponding to genomic species v, vi and vii as found in a previous study. the results were supported by sequencing analyses of rrs, igs, atpd and reca genes. genospecies vii was most related to mesorhizobium septentrionale, while ge ...200818984702
diversity of endophytic bacteria within nodules of the sphaerophysa salsula in different regions of loess plateau in china.a total of 115 endophytic bacteria were isolated from root nodules of the wild legume sphaerophysa salsula grown in two ecological regions of loess plateau in china. the genetic diversity and phylogeny of the strains were revealed by restriction fragment length polymorphism and sequencing of 16s rrna gene and enterobacterial repetitive intergenic consensus-pcr. their symbiotic capacity was checked by nodulation tests and analysis of nifh gene sequence. this is the first systematic study on endop ...201121303396
