Olive mill wastes (OMWs) are high-strength organic effluents, which upon disposal can degrade soil and water quality, negatively affecting aquatic and terrestrial ecosystems. The main purpose of this review paper is to provide an up-to-date knowledge concerning the microbial communities identified over the past 20 years in olive mill wastes using both culture-dependent and independent approache...

Biological treatment ofhazardous wastes has the potential for effective, practical, and economical remediation ofsome Superfund sites and other hazardous waste problems. Some biological hazardous waste treatments may also be applicable for preventing the occurrence of future hazardous waste sites. From a public health perspective, this technology may allow for the treatment of environmental haz...

Fish lipid contains long-chain n-3 (omega-3) PUFA, particularly EPA (C20:5 n-3) and DHA (C22:6 n-3). Consumptions of these PUFAs have been perceived to be important in human nutrition, health and disease prevention. World fish lipid request continue to increase. Fish lipid that contributes to the nutritional needs is currently being extracted from liver or muscle of cod, herring, mackerel and s...

Organic wastes under consideration are of natural origin that possess biochemical characteristics ensuring rapid microbial decomposition at relatively normal operating conditions. When considering the organic waste treatment we have generally in mind organic mineralization, biological stabilisation and detoxification of pollutants. Most common organic wastes contain compounds that are mainly we...

Environmentalists worry that hazardous wastes produced in industrialized nations are being dumped in cash-starved developing countries--the countries with the least political or economic clout to resist and the fewest resources for managing these toxic imports. Imported waste can pose a serious threat to the health of human populations and ecosystems if not managed appropriately. In 1989, the i...

Proteolytic and/or lipolytic lactic acid bacteria (LAB) were isolated from visceral wastes of different fresh water fishes. LAB count was found to be highest in case of visceral wastes of Mrigal (5.88 log cfu/g) and lowest in that of tilapia (4.22 log cfu/g). Morphological, biochemical and molecular characterization of the selected LAB isolates were carried out. Two isolates FJ1 (E. faecalis NC...

if solid wastes are not collected and disposed properly, can cause environmental pollution which affect human health, animals and plants. also aesthetic aspect of solid waste disposal is important. therefore proper management is necessary. this study was carried out for the identification and classification of solid waste produced by oil drilling company temporary camps based on rcra act and un...

One of the critical global environmental problems is human and ecological exposure to hazardous wastes from agricultural, industrial, military and mining activities. These wastes often include heavy metals, hydrocarbons and other organic chemicals. Traditional field and laboratory detection and monitoring of these wastes are generally expensive and time consuming. The synoptic perspective of ov...

Two major nitrogenous waste products, urea and ammonium (NH(4)(+)), are produced in humans when proteins are oxidized, and in this manuscript their excretions are examined from two perspectives. First, the specific physiology of each nitrogenous waste is reviewed and the current dogmas summarized. Second, their excretions are considered in the context of integrative physiology, i.e. the need to...
