Rapid growth in urbanization and industrialization has increased the levels of heavy metals in the environment and consequently in the food chain. Consumption of contaminated food by human beings and other animals may pose a serious threat to their health. Vegetables are a major portion of the human diet, providing microand macronutrients, fibers, antioxidants, vitamins, etc. Vegetables are oft...

Maximizing recovery and characterization of extractable proteins from secondary paper sludge is essential to explore the potential value from utilization of readily available waste products from pulp and paper mills. A multistep physicochemical recovery process was used, involving optimum alkaline solubilization of protein into an aqueous phase followed by augmented physical disruption of cell ...

Other laboratories have reported biphasic effects of heavy metals on protein kinase C activity: stimulation followed by inhibition at higher concentrations. We demonstrate that these earlier findings most likely resulted from a combination of the effect of the heavy metals to liberate Ca2+ from Ca2+-EGTA buffer systems and the direct inhibitory effects of the metals on protein kinase C. Simulat...

Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...

background: developmental activities especially the establishment of more than 20 industrial units in semnan province caused the officers worries about increased concentration of heavy metals in drinking water supplies and probably increasing of health risk at consumers. the aim of the study was to investigate the effect of semnan province industrial development on the health risk level caused ...

Cupriavidus sp. HMR-1 was isolated from a heavy metal-enriched culture of activated sludge from a wastewater treatment plant in Hong Kong. Here, we release the HMR-1 genome to provide basic genetic characteristics for a better understanding of its multiple heavy metal resistance properties.

Characterized by moderate and almost unchanging microbial growth, stability is an essential aspect ofcompost quality Low growth rates give benign organisms a competitive advantage over pathogens such as Sulnronellu and &fhrurn, which thnve m high-growth-rate conditions (Inbar et al., 1990). Also, stability prevents nutrients from becommg tied up in rapid microbial growth, allowing them to be av...
