bioflocculation behaviours of microbial communities in water treatment.we studied the flocculation behaviours of microbial communities in 21 soil, wastewater and activated sludge samples to clarify the effects of culture medium types on flocculation ability and screening efficiency, and to analyze diverse functions and microbial compositions. the bioflocculants produced by 33% of the microbial communities had flocculating efficiencies higher than 90%. six out of the eight microbial communities with efficiencies over 94% were screened from the culture medium using d ...201424569266
sphingobacterium changzhouense sp. nov., a bacterium isolated from a rice field.a gram-stain-negative, yellow, non-spore-forming, rod-shaped bacterium, designated n7(t), was isolated from a soil sample collected from a rice field in jiangsu, china, and was characterized using a polyphasic taxonomic approach. strain n7(t) grew optimally at 25-30 °c, ph 6.0-8.0, and in the presence of 1 % nacl (w/v). 16s rrna gene sequence analysis indicated that strain n7(t) was a member of the genus sphingobacterium and was closely related to sphingobacterium multivorum iam14316(t) (97.49 % ...201323859944
inoculation of sphingobacterium multivorum in the prostate by prostate biopsy.this report describes three cases of infection with sphingobacterium multivorum after transrectal ultrasound-guided prostate biopsy. the pathogen is ubiquitous in water and soil but has been described fewer than 10 times causing infections in humans. an infection hygiene evaluation identified and changed a step in the biopsy process in order to reduce the risk of inoculating the patient with environmental microorganisms.201423834407
production of ginsenoside aglycons and rb1 deglycosylation pathway profiling by hplc and esi-ms/ms using sphingobacterium multivorum gin723.using enrichment culture, sphingobacterium multivorum gin723 (kccm80060) was isolated as having activity for deglycosylation of compound k and ginsenoside f1 to produce ginsenoside aglycons such as s-protopanaxadiol (ppd(s)) and s-protopanaxatriol (ppt(s)). through blast search, purified enzyme from s. multivorum gin723 was revealed to be the outer membrane protein. the purified enzyme from s. multivorum gin723 has unique specificity for the glucose moiety. however, it has activity with ppd and ...201323812276
sphingobacterium caeni sp. nov., isolated from activated sludge.the taxonomic status of a bacterium, strain dc-8(t), isolated from activated sludge, was determined using a polyphasic taxonomic approach. the cells of strain dc-8(t) were gram-negative, non-motile, non-spore-forming and rod-shaped. the isolate grew at temperature range of 10-40 °c (optimum 30-35 °c), ph range of 5.0-10.0 (optimum 6.5-8.0) and nacl concentrations of 0-5% (optimum 0-1%). the predominant menaquinone of strain dc-8(t) was mk-7 and major fatty acids were summed feature 3 (c16:1ω6c a ...201323148100
sphingobacterium cladoniae sp. nov., isolated from lichen, cladonia sp., and emended description of sphingobacterium siyangense.a strictly aerobic, gram-stain-negative bacterium, designated strain no.6(t), was isolated from a lichen (cladonia sp.) collected in geogeum island, korea, and its taxonomic status was established by a polyphasic study. cells of strain no.6(t) were non-motile, catalase- and oxidase-positive, non-spore-forming rods. growth was observed at 15-35 °c (optimum, 25-30 °c), at ph 5.0-10.0 (optimum, ph 6.0-8.0) and with 0-3 % nacl (optimum, 0-2 %). the predominant cellular fatty acids were summed featur ...201322561594
sphingobacterium detergens sp. nov., a surfactant-producing bacterium isolated from soil.a novel gram-negative-staining strain, designated 6.2s(t), was isolated from a soil sample and identified as a biosurfactant producer. its taxonomic position was investigated using a polyphasic approach. the cells were non-motile, non-spore-forming rods. the organism grew optimally at 30-37 °c, with 0-3% (w/v) nacl, and at ph 7.0. based on 16s rrna gene sequence analysis, strain 6.2s(t) was found to be a member of the genus sphingobacterium and was most closely related to four type species of th ...201222307508
