Important microorganisms in wastewater treatment,home remedies for sinus cold congestion,bacterial infection for males - Step 1

Rehabilitation using existing technology, such as activated sludge, is very costly and often there is not enough land. MiraCarbon in anaerobic and contact aeration tank promotes the biological decomposition of contaminants. MiraCarbon in a filtration treatment tank, increases adsorption of contaminants and promote biodegradation.
Uses metabolism abilities of microorganisms to remove pollutants and contaminants.  Algae have tremendous potential to be used for waste water remediation and using algae in a wider scope compared to current commercial use is being emphasized. Combining algae for waste water remediation with biofuel production is an economically feasible process. The composition of effluent from industries is a lot different from the composition of domestic wastes. Algae are used for waste water treatment as they remove undesirable substances by biodegradation.

The waste water treatment plants are an invaluable source of algal biomass which serve as a bright prospect for many industries and companies that use algae as a feedstock for a variety of purposes. Treatment of industrial effluent is targeted at the removal of excess concentrations of nitrogen, phosphorus and other organic matter. Organic matter in water is broken down to smaller components such as CO2, ammonia and phosphates. Toxicity bioassays based on bioluminescent microorganisms are an interesting complement to classical toxicity assays, providing easiness of use, rapid response, mass production, and cost effectiveness. A description of the characteristics and main environmental applications in ecotoxicity testing of naturally bioluminescent microorganisms, covering bacteria and eukaryotes such as fungi and dinoglagellates, is reported in this chapter.

Quantitative structure-activity relationship models and hormesis are two important concepts in ecotoxicology; bioluminescent microorganisms have played a pivotal role in their development. As pollutants usually occur in complex mixtures in the environment, the use of both natural and recombinant bioluminescent microorganisms to assess mixture toxicity has been discussed.
