Since a biological filter with nitrifying bacteria was firstly applied to aquatic animal experiments in IML-2 mission, the reactor system has been further studied to combine both nitrifying and denitrifying reactions under aerobic environment allowing an efficient removal of inorganic nitrogen from animal wastes. The isolated denitrifying bacteria had an activity under aerobic condition with ri...

Polyphenolic compounds are a group of secondary metabolites in plants; these molecules widely distributed fruits, vegetables, and herbs can be found the vacuoles plant cells. The current trend is their extraction to study applications several areas, such as food, cosmetic, pharmacology industry. This review article presents critical analysis polyphenol using solid-state fermentation. parameters...

Before the industrial wastes, this river was unpolluted. Our globe is more than half water, and as a result of various factors, including people's activity, among most prominent which wastes chemicals, it becoming contaminated every day. Water exists in all three states matter—liquid, solid, gas., an essential component. But fundamental problem that many anthropogenic natural activities carried...

One benefit of incorporating poultry wastes and arbuscular mycorrhizal fungus (AMF) into soils is an increase in crop yield. However, experimental results vary depend on the kind wastes, setup, characteristics soil. Thus, underlying causes have not yet been fully understood. In other circumstances, inoculation amendment with may clear impact or negative impacts soil microbes plant growth. The e...

Organic wastes are extensively increasing with increased human populations, intensive agriculture and industrialization. The disposal of wastes has become important for a healthy quality of environment. In this regard recycling of utilizable organic wastes is feasible. The recycling of wastes through vermicomposting reduces problems of disposal of organic wastes. Vermicomposting, a novel techni...

hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. removing them into environment without any treatment may cause serious problems for the public health. membrane biological reactor is the combination of the activated sludge and membrane filters. this research has investigated the performance of the nano-filtration i...
