Disposal of solid wastes is a stinging and widespread problem in both urban and rural areas in many developed and developing countries. Municipal solid waste (MSW) collection and disposal is one of the major problems of urban environment in most countries worldwide today. MSW management solutions must be financially sustainable, technically feasible, socially, legally acceptable and environmentally friendly. Solid waste management issue is the biggest challenge to the authorities of both small and large cities’.Valorization of food organic waste is one of the important current research areas. The conventional landfill, incineration, composting, and ways of handeling solid wastes are common as mature technologies for waste disposal. Traditionally, the most commonly used technologies for the treatment and valorization of the organic fraction of MSW are composting and anaerobic digestion (AD). The generation of organic solid waste (OSW); worldwide; is dramatically increasing each year. Most of the OSW’s are composed of agricultural waste, household food waste, human and animal wastes, etc. They are normally handled as animal feed, incinerated or disposed to landfill sites. OAW’s are comprised of materials rich in proteins, minerals, and sugars that could be used in other processes as substrates or raw materials. 相似文献

Mycotoxins have attracted global attention because of their worldwide distribution and toxic risk. Deoxynivalenol (DON) is a kind of type-B trichothecenes produced by Fusarium fungi and causes great concerns in different fields. The toxic effects of DON and its two acetylated forms of 3-acetyl deoxynivalenol (3-ADON) and 15-acetyl deoxynivalenol (15-ADON) have been studied primarily including hepatotoxicity, intestinal toxicity, nephrotoxicity and reproduction toxicity. Adsorption is one of the widely applied physical methods for DON removal. Different adsorbents including active carbon, montmorillonite and yeast cells have been employed as the materials. Chemical methods involving oxidation and reduction of DON are always conducted by a combination of the ozonation and hydrothermal treatment. Recently, the biological degradation of DON has been intensively studied and found somewhat superior to physical and chemical solutions due to the environmentally friendly property and high specificity. Reported bacteria and the related enzymes that are able to metabolize DON is also comprehensively reviewed, such as the approved Coriobacteriaceae DMS 11798, the well-known Devosia mutans, the PQQ-depend dehydrogenase and the aldo-keto reductase family. 相似文献
