The thorium effect on Bradyrhizobium growth was assayed in liquid media. Th4+ inhibited the growth of Bradyrhizobium (Chamaecytisus) BGA-1, but this effect decreased in the presence of suspensions of live or dead bacterial cells. Th4+ induced the formation of a gel-like precipitate when added to a dense suspension of B. (Chamaecytisus) BGA-1 cells. Viable Bradyrhizobium cells remained in suspension after precipitate formation. Thorium was recovered in the precipitate, in which polysaccharide… Expand
Coprecipitation of Th4+ and the purified extracellular polysaccharide produced by bacterium Bradyrhizobium (Chamaecytisus) BGA-1
The soil bacterium Bradyrhizobium (Chamaecytisus) strain BGA-1 produces an extracellular polymeric substance (EPS) that, in the presence of Fe3+, Al3+ or Th4+ solutions, forms a gel-like precipitateExpand
Morphological changes in an acidophilic bacterium induced by heavy metals
TLDR
It was observed that the maximum alterations in size occurred when the bacterium was exposed to sub-inhibitory concentrations of Cu and Cd, and in growth inhibitory concentrations it was similar to the normal cells. Expand
Effects of thorium on bacterial, microalgal and micromeiofaunal community structures in a periphytic biofilm.
TLDR
It is shown that low concentrations of Th can modify biofilm structure, which, in turn, could disturb its ecologically key functions. Expand
Production of extracellular polymeric substances from Rhodopseudomonas acidophila in the presence of toxic substances
TLDR
Under toxic conditions, the increase in the protein content far exceeded than that of others in EPS, suggesting that extracellular proteins could protect cells against toxic substances. Expand
Exopolysaccharide Carbohydrate Structure and Biofilm Formation by Rhizobium leguminosarum bv. trifolii Strains Inhabiting Nodules of Trifolium repens Growing on an Old Zn–Pb–Cd-Polluted Waste Heap Area
TLDR
Results indicate that studied rhizobia can be assumed as potentially useful in remediation processes, both without exposure to metals and under metal exposure. Expand
Biosorption and Bioaccumulation Abilities of Actinomycetes/Streptomycetes Isolated from Metal Contaminated Sites
Heavy metal pollution is of great concern. Due to expansion of industrial activities, a large amount of metal is released into the environment, disturbing its fragile balance. Conventional methods ofExpand
Biological responses of symbiotic Rhizobium radiobacter strain VBCK1062 to the arsenic contaminated rhizosphere soils of mung bean.
TLDR
Results significantly contribute to better understanding of plant-metal-microbe interactions, cellular-metabolic changes and As-enhanced EPSs, hence can serve as potential bioremediation agent for As-contaminated agrogeoecosystems. Expand
Bioaugmentation with cadmium-resistant plant growth-promoting rhizobacteria to assist cadmium phytoextraction by Helianthus annuus.
TLDR
Results show that plant growth and cadmium accumulation in H. annuus was significantly enhanced by Cadmium-resistant PGPRs, and these bacterial inoculants are excellent promoters of phytoextraction for the rehabilitation of heavy metal-polluted environments. Expand
