The biological reduction and precipitation of uranium in groundwater has the potential to prevent uranium migration from contaminated sites. Although previous research has shown that uranium bioremediation is maximized during iron reduction, little is known on how long-term iron/uranium reducing conditions can be maintained. Questions also remain about the stability of uranium and other reduced...

Bioremediation approaches for the treatment of oily sludge from a refinery were evaluated using a 2(3) factorial design. The three strategies tested were bioaugmentation with indigenous microbial consortia (MO) isolated from oily sludge, biostimulation with nutrients (NP) and biostimulation with the surfactant Triton X-100 (TX). Eight experimental runs were conducted in triplicate with factor s...

the prospects of using the biostimulation and bioaugmentation treatment for the removal of the polychlorinated biphenyl (pcbs) from contaminated sediment collected from the sewage canal in the surroundings of a former pcb manufacturing plant in slovakia is described. the eleven bacterial strains isolated in our previous work from sewage strážsky canal sediments were able to aerobically degrade ...

In a previous study by the authors, toxicity screening of Atrazine-resistant soil bacteria from different contaminated soils resulted in 23-soil isolate best grown in the presence of herbicide Atrazine. They were identified according to their 16S rDNA sequencing into Enterobacter (E. cloacae), Bacillus (B. cereus and B. anthracis), Pseudomonas (P. aeruginosa, P. balearica, P. indica and P. otit...

Laser biostimulation has been found effective in treatment of wound healing and inflammatory conditions. The nature and characteristics of laser light is different from natural light and of conventional light sources. Specifics of the laser include spectral coherence, temporal coherence and spatial coherence [1,2]. In addition, some lasers emit polarized photons and parallel beam. Laser with th...

Chlorinated solvent contamination of potable water supplies is a serious problem worldwide. Biostimulation protocols can successfully remediate chlorinated solvent contamination through enhanced reductive dechlorination pathways, however the process is poorly understood and sometimes stalls creating a more serious problem. Whole metagenome techniques have the potential to reveal details of micr...

BACKGROUND The aim of this paper is to investigate whether laser biostimulation starting on the first day after surgery of the brachial plexus or peripheral nerves has a positive therapeutic effect on wound healing. MATERIAL AND METHODS Surgical procedures were carried out on 44 male Wistar rats. The animals were divided into a control group (Group 1), where the surgical wounds were allowed t...

Dehalococcoides mccartyi strains are of particular importance for bioremediation due to their unique capability of transforming perchloroethene (PCE) and trichloroethene (TCE) to non-toxic ethene, through the intermediates cis-dichloroethene (cis-DCE) and vinyl chloride (VC). Despite the widespread environmental distribution of Dehalococcoides, biostimulation sometimes fails to promote dechlori...

Thread lifting is an innovative method of face and body tissue reinforcement, revitalization and lifting using sterile absorbable PDO(Polydioxanone) mesothreads. After 2000s, minimal invasive technique became popular. As the methods, laser and RF machines were developed rapidly. But the effect wasn't as clear as previous surgical methods. Thread Lifting is the alternative which is less invasive...
