toxic heavy metals, such as lead (pb) and cadmium (cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. twenty four moderately halophilic bacteria isolated from saline environments of iran were used to study their ability to bioremediation of lead and cadmium. amongst them, a gram-negative rod shaped bacterium, de...

The gram negative bacterium Stenotrophomonas is rapidly evolving as a nosocomial pathogen in immuno-compromised patients. Treatment of Stenotrophomonas maltophilia infections is problematic because of their increasing resistance to multiple antibiotics. This article aims to review the multi-disciplinary role of Stenotrophomonas in our environment with special focus on their metabolic and geneti...

A continuous two-phase partitioning bioreactor (C-TPPB), operated with coiled tubing made of the DuPont polymer Hytrel 8206, was tested for the bioremediation of 4-chlorophenol, as a model toxic compound. The tubing was immersed in the aqueous phase, with the contaminated water flowing tube-side, and an adapted microbial culture suspended in the bioreactor itself, with the metabolic demand of t...

One of the major environmental problems facing the world today is the contamination of soil, water and air by toxic chemicals as a result of industrialization and extensive use of pesticides in agriculture. Incineration is currently the most effective and common remediation practice but is costly in terms of money and energy used. A rapid cost effective and ecologically responsible method of cl...

Bioremediation of hydrocarbons in soil is a highly complex process, involving multiplicity physical, chemical and biological phenomena. Therefore, it extremely difficult to control boost the bioremediation these systems after an oil spill. A mathematical model was developed assist prediction decision-making regarding situ hydrocarbon-contaminated soils. The considered most relevant processes in...

The optimised reduction of dissolved nutrient loads in aquaculture effluents through bioremediation requires selection of appropriate algal species and strains. The objective of the current study was to identify target species and strains from the macroalgal genus Ulva for bioremediation of land-based aquaculture facilities in Eastern Australia. We surveyed land-based aquaculture facilities and...
