Control Water

With the increasing of water pollution, water eutrophication is seriously affecting people’s daily life and production. Therefore, it is particularly important to explore safe and efficient algae control technology. In the current algal bloom treatment methods, the physical method is not complete in algae dissolving, and the cost of algal control is high. The chemical method is easy to produce secondary pollution and toxic by-products, and the safety is not high. However, the biological method has the advantages of low cost, high ecological security and good ecological compatibility. It is considered to be a more promising method to remove algae and biological toxins, and it is also an inevitable trend to control water eutrophication in the future.

Olive Mill

Anaerobic digestion of olive-mill wastewater (OMW) was carried out in a continuously fed mode bioreactor. The bioreactor was operated at different hydraulic retention times (HRTs), using OMW, either raw or pre-treated with white-rot fungi. Two different kinds of feed were tested in this process, one which was thermally treated and subjected to sedimentation, in order to remove the solids contained and the other without any physicochemical treatment (raw OMW). Thermally pretreated OMW did not allow a stable operation even at an HRT of 30d. Further pretreatment of the OMW with a white-rot fungus for removal of the contained phenolics, allowed a stable operation at an HRT of 30 d. On the other hand, simple dilution of the raw wastewater, without any solids removal, lead to a stable operation at an HRT of 30d and was accompanied by higher production of biogas. The presence of the solids in the OMW proved to be a determining factor for the stability of the process and could be attributed to a possible adsorption on the solids of hydrophobic compounds, such as long-chain fatty acids that are toxic to methanogens.

Agri-food industry generally produces huge volumes of wastes all over the world, and their disposal is a threat to the environment and public health. The chemical composition of most of these wastes make them be defined as lignocellulosic materials, so they could be a suitable substrate for solid-state fermentation process operated by mushrooms. White-rot fungi are well known for their degradation ability of lignocellulosic material, and many scientific works reported the use of different substrates for their production. Biotechnological treatments of agri-food wastes by mushrooms could be considered an eco-friendly solution to reuse and valorize them, besides to reduce their environmental impact. In this way, wastes would be transformed into new resources to produce added-value food products, besides representing an economic return for the same industries. The aim of this review is to provide an overview of the recent literature concerning the use of different agri-food residues as growth substrates for Pleurotus spp. cultivation, with attention to their effects on the growth and chemical composition of the cultivated mushrooms.

ABSTRACTAn improvement in animal feeding is one of the important and basic conditions for the better management of farming of animals. It was recognized that poor quality of the feed is mainly responsible for the poor animal performance. For most farming practices, feed is an expensive component in livestock farming. Alternative feed can be obtained from agricultural by-products with huge amount around the world. The main factors limiting the utilization of agricultural by-products like paddy straw, wheat straw and corn stover are their low digestibility, low protein content and some time low palatability. However, the nutritive value of the agricultural by-products can be enhanced through their biological treatment and hence play an important role to meet nutrient requirements of the animals. Thus, an alternative approach is biological treatment especially fungi to increase digestibility of agricultural by-products. The use of white rot fungi, brown rot fungi and soft rot fungi that metabolize lignocelluloses is a potential biological treatment to improve the nutritional value of agricultural by-products. This paper aims to discuss the role of fungi in increasing the nutritional value of agricultural by-products like paddy straw, wheat straw and corn stover.Keywords: Agricultural by-products, Biological treatment, fungi, Lignocelluloses

Environmental applications of enzymes in biodegradation for preventing pollution by toxic byproducts warrants approaches that can be performed under mild conditions, are economically feasible and can replace the use of chemicals. Technologies involving physico-chemical methods, like incineration, dechlorination and UV oxidation, for waste treatment are not acceptable since they generate a lot of pollutants as by-products. To address these problems, environmental–friendly alternatives are required for bioremediation. In this context, fungal enzymes have emerged as a natural tool to detoxification of pollutants in environment, and the potential to convert toxic substances to less hazardous or non-hazardous forms. However, what are the effective advances by using white-rot fungi for bioremediation? Here, a brief discussion about the application of these fungi to detoxification of pollutants in environment has been considered.

The final effluents from pulp and paper industry, even after biological treatment, often contain a plethora of unwanted by-products, which confer them colour and toxic characteristics. The aim of this work was to promote degradation of organic matter and remove colour by contacting fungi Pleurotus sajor caju or P. ostreatus with effluents from kraft pulp mill after treatment by an activated sludge process. Absorbance reduction of 57 and 76 % was observed after 14 days of treatment of final effluent with glucose by P. sajor caju, at 400 and 460 nm, respectively. Lower values of absorbance reduction were observed in final effluent with additives and inoculated with the same species (22 to 29%). Treatment with P. ostreatus was more efficient in the effluent with additives, 38.9 to 43.9% of reduction. Higher growth rate of P. sajor caju was observed in the effluent with glucose. Biological treatment resulted in 65-67% reduction of COD after 14 days revealing no differences for each effluent composition and inoculated species. Profiles of composition of organic compounds obtained by GC-MS showed no significant differences between the two effluents treated with P. sajor caju or P. ostreatus, but longer incubation time reflected higher reduction of organic compounds.
