“…Mushrooms from the genus Pleurotus have been widely studied and cultivated in many lignocellulosic substrates [18,19]. In China and Colombia organic wastes, including aquatic weeds, have been used as substrates for these mushrooms [17,20]. In Latin-America, Pleurotus is the second produced mushroom after champignons, being Mexico the main producer on the continent [21].…”

Purpose This work assesses the feasibility of the valorization of water hyacinth, which grows in the canals of Xochimilco, México, through its use as substrate for the cultivation of edible mushrooms and forage. Methods Water hyacinth was processed using different pretreatments, producing four different substrates in which the mushroom was cultivated. The degradation of the substrate was estimated by its weight reduction, the biomass generation was measured, and the biological efficiency was calculated. The possible presence of cadmium and lead was determined by atomic absorption spectrophotometry in the fruiting bodies and in substrates (before and after the cultivation of the mushrooms). The potential of the substrate to be used as forage was determined through a proximate analysis. Results From all the inoculated substrates, the mushroom fructified only in two (humid and sterilized water hyacinth; and humid, pre-composted, and pasteurized water hyacinth with roots). Humid and sterilized water hyacinth was the best treatment, with a biological efficiency of 310.44 % ± 85.27. The weight reduction of this treatment was similar to that of the straw, which was used as a control. For both treatments, there was no presence of Pb and Cd in the fruiting body or in the spent substrate. The results of the proximal analysis showed that the spent substrate has the required characteristics to be used as potential bovine forage.Conclusions This treatment is a feasible alternative for the management of this complex waste, producing a valuable protein source and feed for cattle.

The use of waste apple-wood as a source of sawdust to cultivate the mushrooms Pleurotus ostreatus and Lentinula edodes is a common practice, but it is imperative to ensure that the wood does not contain unsafe amounts of heavy-metals or pesticide residues. In this study, we sampled and investigated the pollution of heavy metals and pesticide residues in apple-wood from Yantai, Shandong, China and cultivated P. ostreatus and L. edodes using apple-wood as substrate. Heavy metals, pesticide residues, mineral elements, and biological efficiency were measured. Heavy metals were more commonly detected in the 73 apple-wood samples, but serious pollution was only an isolated phenomenon. No Pb was detected in P. ostreatus and L. edodes. The contents of Hg, As, Cd, and Cr were at safe levels. The contents of Ni were equivalent to those of wild mushrooms. Most notably, chlorpyrifos was detected in all the apple-wood tested. However, chlorpyrifos was only detected in L. edodes cultivated with apple sawdust. No other pesticide residues were detected in the other mushroom samples. The biological efficiency of P. ostreatus cultivated by apple sawdust was 89%, which was 80% of the control. The biological efficiency of L. edodes cultivated with apple sawdust was 81%, which did not differ significantly from the control. Apple-wood can replace wild oak as the material for L. edodes cultivation, but producers should ensure that the raw materials are safe. The main materials chosen to cultivate P. ostreatus should balance the two factors of raw material price and biological efficiency.
