arthrobacter oryzae sp. nov. and arthrobacter humicola sp. nov.two novel bacterial strains were isolated from a paddy soil sample collected in japan using gpm agar plates supplemented with superoxide dismutase and/or catalase. the strains were gram-positive, catalase-positive and motile, with lysine as the peptidoglycan diagnostic diamino acid and acetyl as the peptidoglycan acyl type. the major menaquinone was mk-9(h(2)). mycolic acids were not detected. the g+c content of the dna was 66-68 mol%. on the basis of phenotypic analysis, 16s rrna gene sequence ...200818175682
arthrobacter nanjingensis sp. nov., a mineral-weathering bacterium isolated from forest soil.a gram-stain-positive, non-motile, rod- or coccoid-shaped actinobacterium, designated strain a33(t), was isolated from a forest soil sample from nanjing, jiangsu province, pr china. the strain grew optimally at 30 °c, ph 7.0 and with 3 % nacl (w/v). phylogenetic analysis of the strain, based on 16s rrna gene sequences, showed that it was most closely related to arthrobacter woluwensis (98.4 % sequence similarity), arthrobacter humicola (97.5 %), arthrobacter globiformis (97.4 %), arthrobacter or ...201525358511
micrococcoides hystricis gen. nov., sp. nov., a novel member of the family micrococcaceae, phylum actinobacteria.a gram-stain-positive bacterium, designated tsl3t, was isolated from faeces of a porcupine, hystrix indica, from the budapest zoo and botanical garden, hungary. on the basis of 16s rrna gene sequence analysis, the strain is phylogenetically related to the family micrococcaceae. the highest 16s rrna gene sequence similarity was found with micrococcus terreus v3m1t (96.50 %) followed by arthrobacter humicola kv-653t (96.43 %). cells of strain tsl3t were aerobic, non-motile and coccoid-shaped. the ...201728853684
flocculating performance of a bioflocculant produced by arthrobacter humicola in sewage waste water treatment.the discharge of poorly treated effluents into the environment has far reaching, consequential impacts on human and aquatic life forms. thus, we evaluated the flocculating efficiency of our test bioflocculant and we report for the first time the ability of the biopolymeric flocculant produced by arthrobacter humicola in the treatment of sewage wastewater. this strain was isolated from sediment soil sample at sterkfontein dam in the eastern free state province of south africa.201728606076
