The diversity, community structure and vertical distribution characteristics of bacteria in the surface subsurface soil water samples a closed landfill Shanghai Jiading District were investigated to reveal relationships between natural waste degradation degree succession bacterial composition. High-throughput sequencing 16S rDNA genes was used analyze diversity. results showed that diversity hi...

Background and Purpose: The Phytoremediation efficiency of heavy metals is one of the important points in environmental studies. This research was conducted to investigate the effect of cow manure, elemental sulfur, and EDTA on Cd uptake by Indian mustard in a Cd-polluted soil in the presence of Thiobacillus thiooxidans. Materials and Methods: Treatments consisted of applying cow manure (0, 5,...

The composition of bacterial populations in copper bioleaching systems was investigated by analysis of DNA obtained either directly from ores or leaching solutions or after laboratory cultures. This analysis consisted of the characterization of the spacer regions between the 16 and 23S genes in the bacterial rRNA genetic loci after PCR amplification. The sizes of the spacer regions, amplified f...

Charge and softness of the outer part of the cell wall of Thiobacillus ferrooxidans in the low ionic strength medium The surface charge and surface potential are parameters influencing the microbial adhesion phenomenon through the electrostatic interaction between bacteria and substrates. The Smoluchowski equation, originally developed for estimating the above parameters from the experimentally...

in order to evaluate of biological fertilizers and micronutrient elements effects on yield and some agronomic traits in rapeseed (brassica napus l.), an experimental was performed as factorial arrengement based on randomized complete blocks design with three replications in 2012-13 in research station of shahid chamran university of ahvaz, iran. in this experiment, micronutrient elements were i...

Sulfate-reducing bacteria (SRB) have been studied extensively in the petroleum industry due to their role in corrosion, but very little is known about sulfur-oxidizing bacteria (SOB), which drive the oxidization of sulfur-compounds produced by the activity of SRB in petroleum reservoirs. Here, we surveyed the community structure, diversity and abundance of SRB and SOB simultaneously based on 16...

The chromosomal arsenic resistance genes of the acidophilic, chemolithoautotrophic, biomining bacterium Thiobacillus ferrooxidans were cloned and sequenced. Homologues of four arsenic resistance genes, arsB, arsC, arsH, and a putative arsR gene, were identified. The T. ferrooxidans arsB (arsenite export) and arsC (arsenate reductase) gene products were functional when they were cloned in an Esc...

Thiobacillus denitrificans is physiologically similar to the type species of the genus Thiobacillus, Thiobacillus Thioparus, and both are located in the beta-subclass of the Proteobacteria. T. denitrificans is distinguished from all other Thiobacillus species by its ability to grow as a facultatively anaerobic chemolithotroph, coupling the oxidation of inorganic sulfur compounds to the reductio...

Background & Aim: In order study the effect of Thiobacillus, sulphur and organic materials on vegetative growth and essence production in lemon balm (Melissa officinalis L.) was conducted in pots in field condition at Shahrekord, Iran on 2008. Experimental: The factors were ten soil treatments inclusive 200 kg/ha sulphur, 400 kg/ha sulphur, 600 kg/ha sulphur, 200 kg/ha sulphu...
