“…Such applications have a long history, and already 50 years ago Fiestas Ros de Ursinos (1961) reported the production of yeast biomass using OMWW in a chemostat for use in industrial applications. A few edible fungi, especially species of Pleurotus, can also be grown using OMWs as the source of nutrients by the application of different strategies (Kalmis et al 2008;Sanjust et al 1991;Zervakis et al 1996). These authors also reported biochemical changes and detoxification of the substrates due to the active excretion of ligninolytic enzymes and partial consumption/adsorption of the organic fraction by fungi.…”

“…These authors also reported biochemical changes and detoxification of the substrates due to the active excretion of ligninolytic enzymes and partial consumption/adsorption of the organic fraction by fungi. Kalmis et al (2008) recently suggested the cultivation of the oyster mushroom (Pleurotus ostreatus) on wheat straw substrate containing a mixture of tap water and OMWW (25% OMWW, v/v) as an environmentally friendly solution for the purpose of commercial mushroom production. Similar approaches have been exploited by several small companies for more than a decade (Ramos-Cormenzana et al 1995).…”

Olive-mill wastes are produced by the industry of olive oil production, which is a very important economic activity, particularly for Spain, Italy and Greece, leading to a large environmental problem of current concern in the Mediterranean basin. There is as yet no accepted treatment method for all the wastes generated during olive oil production, mainly due to technical and economical limitations but also the scattered nature of olive mills across the Mediterranean basin. The production of virgin olive oil is expanding worldwide, which will lead to even larger amounts of olive-mill waste, unless new treatment and valorisation technologies are devised. These are encouraged by the trend of current environmental policies, which favour protocols that include valorisation of the waste. This makes biological treatments of particular interest. Thus, research into different biodegradation options for olive-mill wastes and the development of new bioremediation technologies and/or strategies, as well as the valorisation of microbial biotechnology, are all currently needed. This review, whilst presenting a general overview, focusses critically on the most significant recent advances in the various types of biological treatments, the bioremediation technology most commonly applied and the valorisation options, which together will form the pillar for future developments within this field.

“…Nevertheless, increased pH value can have disinfecting effect against competing microorganisms in the substrate (Hérnandez et al, 2003). Kalmis et al, (2008) determined the optimal pH range for mycelium growth and fruit body formation as 6.5 -7. Jablonský and Šašek (2006) state that optimal pH range for mycelium growth is 5.5 -6.5.…”

In this study, we chemically treated apple tree chips and evaluated the colonisation of these substrates by the mycelium of Pleurotus. ostreatus. Chips were treated by a liquid surfactant Empigen OB (0.02 -0.32 %), calcium hydroxide Ca(OH)2 (1 -3 %) and sodium hypochlorite NaClO (0.5 -1.5 %), and by their combinations. Substrates treated with a combination of the Empigen and NaClO reached the pH values of 6.5, with a combination of the Empigen and hydroxide, pH values did not exceed 7.9. Significantly higher gains of P. ostreatus mycelium 15 days after inoculation were found for the substrate treated with 2 % Ca(OH)2 and in the substrate treated with 0.08 % Empigen. The majority of substrates treated with the combination of NaClO and the Empigen showed significantly higher mycelium gains 15 days after inoculation compared to the control. The best results were obtained with the combination 0.08 % Empigen + 1.5 % NaClO. These results indicate positive synergic effect of the Empigen and NaClO. Collectively, treatment of the substrate based on apple tree chips by surfactant Empigen, Ca(OH)2 and NaClO (apart from the combination of the surfactant and Ca(OH)2 seem to be a suitable approach for substrate preparation.

“…Bettin et al (2011) observed that suitable pH value for biomass growth was 7.4-7.5. Kalmis et al (2008) suggested that optimum pH for biomass growth is at between 6.5 and 7.0. Temperatures of 15 °C and 37 °C were not suitable for the biomass production.…”

The lignocellulolytic enzymes are routinely produced by submerged fermentation using lignocellulosic material, but for more effective production, it would be suitable to precede the production phase on the lignocellulose by propagation phase in the nutrition medium suitable for growth of the fungi. Therefore, the aim of this study was to increase the laccase production by the white-rot fungus Pleurotus ostreatus by two-step cultivation strategy. In the first step, propagation medium was optimized for the maximal biomass growth, the second step included the laccase production by produced fungal biomass in media with the selected lignocellulosic material (pine sawdust, alfalfa steam and corn straw). From our experiments, parameters such as glucose concentration, yeast extract concentration and pH of propagation medium were selected as key factors affecting growth of P. ostreatus. The optimal conditions of propagation medium for maximal fungal growth determined by response surface methodology were: glucose concentration 102.68 g/L, yeast extract concentration 43.65 g/L and pH of propagation medium 7.24. These values were experimentally verified and used statistical model of biomass production prediction was appropriate adjusted. Thus prepared fungal biomass produced in the media with lignocellulose approximately 9-16 times higher concentrations of the laccase in 3 times shorter time than the fungal biomass without propagation phase in optimized propagation medium.
