| alcaligenes aquatilis sp. nov., a novel bacterium from sediments of the weser estuary, germany, and a salt marsh on shem creek in charleston harbor, usa. | four nitrite-dissimilating strains, isolated from weser estuary sediments, were investigated using a polyphasic taxonomic approach. phylogenetic analysis based on 16s rrna gene sequences indicated that these strains belong to the 'betaproteobacteria' and are related to the genus alcaligenes. the highest level of sequence similarity (100 %) was found with strain m3a (=atcc 700596), a dimethyl sulfide-producing marine isolate that was included in this study. dna-dna hybridizations between the five ... | 2005 | 16280529 |
| castellaniella gen. nov., to accommodate the phylogenetic lineage of alcaligenes defragrans, and proposal of castellaniella defragrans gen. nov., comb. nov. and castellaniella denitrificans sp. nov. | comparative 16s rrna gene sequence analysis indicates that two distinct sublineages exist within the genus alcaligenes: the alcaligenes faecalis lineage, comprising alcaligenes aquatilis and a. faecalis (with the three subspecies a. faecalis subsp. faecalis, a. faecalis subsp. parafaecalis and a. faecalis subsp. phenolicus), and the alcaligenes defragrans lineage, comprising a. defragrans. this phylogenetic discrimination is supported by phenotypic and chemotaxonomic differences. it is proposed ... | 2006 | 16585701 |
| wheat bran enhances the cytotoxicity of immobilized alcaligenes aquatilis f8 against microcystis aeruginosa. | algicidal bacteria offer a promising option for killing cyanobacteria. therefore, a new alcaligenes aquatilis strain f8 was isolated to control microcystis aeruginosa in this study. the algicidal activity of strain f8 was dependent on the cell density of m. aeruginosa, and the maximal algicidal rate of the free bacterium reached 88.45% within 72 h. with a view to its application to the control of m. aeruginosa in the natural environment, strain f8 was immobilized in sodium alginate beads, but im ... | 2015 | 26295573 |
| alcaligenes endophyticus sp. nov., isolated from roots of ammodendron bifolium. | a gram-staining negative, rod-shaped, motile bacterium, designated aer10t, was isolated from roots of ammodendron bifolium collected from takeermohuer desert in xinjiang uygur autonomous region, north western china. growth was found to occur from 10°c to 45°c, at ph 5.0-9.0 and could tolerate nacl up to 10 % (w/v). 16s rrna gene sequence result indicated that the strain aer10t belongs to the genus alcaligenes and was closely related to alcaligenes aquatilis (98.4 %), alcaligenes faecalis subsp. ... | 2016 | 27959788 |
| anoxic biodegradation of isosaccharinic acids at alkaline ph by natural microbial communities. | one design concept for the long-term management of the uk's intermediate level radioactive wastes (ilw) is disposal to a cementitious geological disposal facility (gdf). under the alkaline (10.0<ph>13.0) anoxic conditions expected within a gdf, cellulosic wastes will undergo chemical hydrolysis. the resulting cellulose degradation products (cdp) are dominated by α- and β-isosaccharinic acids (isa), which present an organic carbon source that may enable subsequent microbial colonisation of a gdf. ... | 2015 | 26367005 |
