variovorax defluvii sp. nov., isolated from sewage flowing into river geumho in south korea.	a polyphasic taxonomic study was carried out on 2c1-b(t) and 2c-21, two strains isolated from the sewage flowing into river geumho in korea.the cells of strains were gram-negative, non-spore-forming, motile and oval or rod-shaped bacteria. comparative 16s rrna gene sequence studies showed a clear affiliation of these two bacteria into the betaproteobacteria, which were most closely related to variovorax boronicumulans kctc 22010(t), variovorax dokdonensis kctc 12544(t), variovorax ginsengisoli k ...	2011	21948092
enhanced mineralization of diuron using a cyclodextrin-based bioremediation technology.	the phenylurea herbicide diuron [n-(3,4-dichlorophenyl)-n,n-dimethylurea] is widely used in a broad range of herbicide formulations and, consequently, it is frequently detected as a major soil and water contaminant in areas where there is extensive use. diuron has the unfortunate combination of being strongly adsorbed by soil organic matter particles and, hence, slowly degraded in the environment due to its reduced bioavailability. n-phenylurea herbicides seem to be biodegraded in soil, but it m ...	2012	22985203
xenophilus arseniciresistens sp. nov., an arsenite-resistant bacterium isolated from soil.	a gram-reaction-negative, aerobic, motile, rod-shaped, arsenite [as(iii)]-resistant bacterium, designated strain yw8(t), was isolated from agricultural soil. 16s rrna gene sequence analysis showed over 97% sequence similarity to strains of the environmental species xenophilus azovorans, xenophilus aerolatus, simplicispira metamorpha, variovorax soli, and xylophilus ampelinus. however, the phylogenetic tree indicated that strain yw8(t) formed a separate clade from xenophilus azovorans. dna-dna hy ...	2014	24585373
isolation and characterization of oxalotrophic bacteria from tropical soils.	the oxalate-carbonate pathway (ocp) is a biogeochemical set of reactions that involves the conversion of atmospheric co2 fixed by plants into biomass and, after the biological recycling of calcium oxalate by fungi and bacteria, into calcium carbonate in terrestrial environments. oxalotrophic bacteria are a key element of this process because of their ability to oxidize calcium oxalate. however, the diversity and alternative carbon sources of oxalotrophs participating to this pathway are unknown. ...	2015	25381572
variovorax guangxiensis sp. nov., an aerobic, 1-aminocyclopropane-1-carboxylate deaminase producing bacterium isolated from banana rhizosphere.	a 1-aminocyclopropane-1-carboxylate deaminase producing bacterium, designated gxgd002(t), was isolated from the rhizosphere of banana plants cultivated in guangxi province, china. phylogenetic analysis based on 16s rrna gene sequences revealed that strain gxgd002(t) is a member of the genus variovorax. high levels of 16s rrna gene sequence similarity are found between strain gxgd002(t) and variovorax paradoxus dsm 30034(t) (99.4 %), variovorax ginsengisoli kctc 12583(t) (99.1 %), variovorax boro ...	2015	25504533
evaluation of biostimulation and tween 80 addition for the bioremediation of long-term ddt-contaminated soil.	the bioremediation of a long-term contaminated soil through biostimulation and surfactant addition was evaluated. the concentrations of 1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane (ddt) and its metabolites 1,1-dichloro-2,2-bis(4-chlorophenyl) ethane (ddd) and 1,1-dichloro-2,2-bis(4-chlorophenyl) ethylene (dde) were monitored during an 8-week remediation process. physicochemical characterization of the treated soil was performed before and after the bioremediation process. the isolation and id ...	2015	25662244

exploiting the fungal highway: development of a novel tool for the in situ isolation of bacteria migrating along fungal mycelium.	fungi and bacteria form various associations that are central to numerous environmental processes. in the so-called fungal highway, bacteria disperse along fungal mycelium. we developed a novel tool for the in situ isolation of bacteria moving along fungal hyphae as well as for the recovery of fungi potentially involved in dispersal, both of which are attracted towards a target culture medium. we present the validation and the results of the first in situ test. couples of fungi and bacteria were ...	2015	26432804
bioremediation of diuron contaminated soils by a novel degrading microbial consortium.	diuron is a biologically active pollutant present in soil, water and sediments. it is persistent in soil, water and groundwater and slightly toxic to mammals and birds as well as moderately toxic to aquatic invertebrates. its principal product of biodegradation, 3,4-dichloroaniline, exhibits a higher toxicity than diuron and is also persistent in the environment. on this basis, the objective of the study was to determine the potential capacity of a proposed novel diuron-degrading microbial conso ...	2017	28011373
