Edible mushroom agribusiness from sugar industry byproducts and spent substrates management
The sugar industry in Veracruz, Mexico participates with 38%25 of the national production of sucrose. However, it has challenges related to low agricultural productivity, derived from conventional practices of crop management, burning of trash and bagasse, effects of climate change and other socio-economic aspects are a risk to competitiveness and sustainability. Besides, from processing of sugarcane generates byproducts in the field (trash, flowers, tops and leaves) and bagasse in sugar mills and trapiches; which for sustainable management, must be developed new productive alternatives; as the edible mushroom production, and the establishment of competitive agribusinesses within the value chain. The aim of this study, was to evaluate the potential of agro-industrial sugar cane harvest and sugar industry byproducts in Veracruz, as lignocellulosic substrates, for the production of edible mushroom Pleurotus ostreatus by several method of pasteurization, and the production of organic fertilizers from the spent substrates, to close the production cycle in a sustainable way. Productivity indicators varied significantly from 20 to 103 for BE (%25), the production rate of 0.51 to 3.85 and yield of 5.45 to 32%25. Therefore, sugar industry byproducts are considered a competitive substrate for the sustainable production Pleurotus ostreatus. Besides, the organic fertilizers, obtained from spent susbtrates, showed physico-chemical properties as pH (8.97 to 8.99), organic matter (42 to 49.5%25), N (0.9 to 1%25), P (1 to 1.7%25), K (1.2%25) and C/N (24 to 32); suitable for restoring acidic soils, degraded by monocultures, and low organic matter content for the production of foods such as vegetables, fruits and other planting crops. © 2017 by Nova Science Publishers, Inc.
