{Abstract}: Olive mill wastewater (OMW) generated during the oil extraction from Olea europea L. var. koroneiki olives was sampled at the beginning, the middle and the end of the harvesting season for three successive crop production years, and from four olive mills. OMW samples were examined in respect to their physicochemical characteristics, fatty acid composition of the lipid fraction, and adverse effects on biomass production of nine white-rot fungi of the basidiomycetous genus Pleurotus. Total N, nitrogen species, potassium and phosphate concentrations as well as total phenolics content of OMW samples were influenced by the crop year but not from the harvest period (albeit higher values for nitrate, nitrite, phosphate and potassium as well as total phenolics contents were obtained during ripening of olives), whereas protein concentration, total organic carbon and total solids were not significantly affected by the crop year or the harvest period. In addition, fatty acids composition, i.e. nC14:0, nC16:19cis, nC17:110cis, nC18:0, nC18:19cis, nC22:0 and nC24:0 varied significantly during different crop years and harvest periods. Olive fruits maturity and biannual alternate-bearing appear to play key-roles in the fatty acid variation detected in OMW samples. OMW toxicity as evaluated by the mycelium growth of Pleurotus strains was influenced significantly by the phenolic content of OMW samples obtained during three successive crop years; in contrast, the olives harvest period did not affect Pleurotus biomass production. Hence, experimental data indicated that selected Pleurotus strains could serve as bioindicators of OMW toxicity. Development of viable OMW detoxification processes as well as the exploitation of the effluent's fertilizing value are discussed in the light of the above findings.   2013 Elsevier Ltd.

{Abstract}: Cow manure and rice stalk were composted to produce Agaricus bisporus. The effects of different C/Ns (30: 1, 32.5: 1, 35: 1, 37.5: 1, 40: 1) of compost on cultivation of Agaricus bisporus was investigated to provide data for mass production of Agaricus bisporus in Northeast of China. The results showed that the compost with C/N ratio of 32.5:1 had higher composting temperature, shorter full growth time in the substrate(18d), shorter time of emergence of primordium (32d), higher biological efficiency(28.8%). Compost with C/N of 32.5:1 was recommended to be extended in mass production of Agaricus bisporus.

{Abstract}: In this study, a novel isolate <em class="a-plus-plus">Aspergillus candidus</em> was employed for xylanase production using low cost agro residues. A Box-Behnken design matrix was used to optimize the influential parameters like carbon source, nitrogen source and incubation temperature for maximum xylanase production. Under optimized condition, enzyme titer level enhanced to 69?IU/ml at 48?h with volumetric productivity 1437?IU/l?h. Growth and enzyme production were observed even at pH 11.0, indicating its ability to sustain at high alkaline environment. Little amount of cellulase was produced concomitantly with xylanase during the course of the process. Volumetric productivity of xylanase was found as a function of temperature. This fungal strain was emerged as a one among few strains having high xylanase productivity.

{Abstract}: This study was aimed to investigate the effect of carbon and nitrogen sources on the production of bioactive total dietary fibres (TDF) and glucans (alpha- and beta-glucans) in submerged cultures of wild Ganoderma australe and commercial Pleurotus ostreatus, both of Greek origin. The contents of glucans and TDF were determined by using the respective Megazyme enzymatic kits. Glucose and yeast extract (YE) were suggested as appropriate carbon and nitrogen sources, respectively, for obtaining simultaneously high production of TDF and beta-glucans by G. australe, which are compounds of great pharmacological interest, whereas maltose and YE were found favourable for high production of the above-mentioned functional components by P. ostreatus. The data obtained in this study provide useful information for further development of the studied mushroom fermentation process on a scale of the bioreactor aiming at enhanced TDF and beta-glucan production.
