Degradation and mineralization of atrazine by a soil bacterial isolate.
An atrazine-degrading bacterial culture was isolated from an agricultural soil previously impacted by herbicide spills. The organism was capable of using atrazine under aerobic conditions as the sole source of C and N. Cyanuric acid could replace atrazine as the sole source of N, indicating that the organism was capable of ring cleavage. Ring cleavage was confirmed in 14CO2 evolution experiment...
متن کاملRhizobium gallicum sp. nov. and Rhizobium giardinii sp. nov., from Phaseolus vulgaris nodules.
Thirty-one strains of two new genomic species (genomic species 1 and 2) of rhizobia isolated from root nodules of Phaseolus vulgaris and originating from various locations in France were compared with reference strains of rhizobia by performing a numerical analysis of 64 phenotypic features. Each genomic species formed a distinct phenon and was separated from the other rhizobial species. A comp...
متن کاملRhizobium calliandrae sp. nov., Rhizobium mayense sp. nov. and Rhizobium jaguaris sp. nov., rhizobial species nodulating the medicinal legume Calliandra grandiflora.
Calliandra grandiflora has been used as a medicinal plant for thousands of years in Mexico. Rhizobial strains were obtained from root nodules of C. grandiflora collected from different geographical regions in Chiapas and characterized by BOX-PCR, amplified rDNA restriction analysis (ARDRA) and 16S rRNA gene sequence analysis. Most isolates corresponded to members of the genus Rhizobium and thos...
متن کاملReclassification of Rhizobium tropici type A strains as Rhizobium leucaenae sp. nov.
Rhizobium tropici is a well-studied legume symbiont characterized by high genetic stability of the symbiotic plasmid and tolerance to tropical environmental stresses such as high temperature and low soil pH. However, high phenetic and genetic variabilities among R. tropici strains have been largely reported, with two subgroups, designated type A and B, already defined within the species. A poly...
متن کاملRhizobium soli sp. nov., isolated from soil.
A Gram-negative, non-motile, pale-yellow, rod-shaped bacterial strain, DS-42(T), was isolated from a soil in Korea and its taxonomic position was investigated by a polyphasic study. Strain DS-42(T) grew optimally at 25 degrees C and pH 7.0-8.0. Strain DS-42(T) did not form nodules on three different legumes, and the nodD and nifH genes were also not detected by PCR. Strain DS-42(T) contained Q-...
