Applicability of the use of waste from different banana cultivars for the cultivation of the oyster mushroom

Abstract

The objective of this research was to evaluate the oyster mushroom Pleurotus ostreatus- (Jacq.: Fr.) Kumm. cultivation in substrates based on different combinations of wastes (leaf, pseudo-stem and pseudo-stem + leaf) and banana cultivars - Musa spp. (Thap Maeo, Prata AnãPelipita and Caipira) during 49 days. Organic matter loss in the substrate by action of the fungus was also evaluated during that period. It was verified that the pseudo-stem waste provided the best averages of biological efficiency among all cultivars tested and best rates were obtained by Thap Maeo (61.5%). The highest organic matter loss (OML) was obtained from pseudo-stem + leaf wastes (Prata Anã 78.6%; Thap Maeo - 67.6%; Pelipita - 64.8%; Caipira - 60.6%). Therefore, the use of those wastes showed itself viable for P. ostreatus cultivation due to its availability and low cost, besides decreasing discards to environment.

Use of lignocellulosic corn and rice wastes as substrates for oyster mushroom (Pleurotus ostreatus Jacq.) cultivation

“…The corn stubble and rice straw reached biological efficiencies greater than 60%. These results are also observed in studies that used other types of agronomic wastes, such as tomato tuff, banana leaves, rice straw, perilla stalks, wheat straw, sawdust, and cotton seeds that presented a C/N ratio between 30 and 50 [5,37,39,42,43]. Similarly, we verified that the intrinsic characteristics of the substrate type have a direct influence on biological efficiency.…”

“…From the inoculation of the substrates, the mycelial growth can be influenced by the chemical composition, plant structure, origin, and particle size of the agronomic wastes used as substrate. Such characteristics, when added to the domain of control of environmental conditions and substrate treatment, will determine the productive performance of mushrooms [5,37].…”

“…Finally, G) the organic matter loss (%), which represents the decomposition of the substrate by the fungus [5], determined by:…”

“…These species are considered excellent lignocellulosic decomposers because of their high rate of mycelial growth and enzymatic capacity. Such characteristics favor their cultivation because they can quickly colonize various agronomic wastes, such as rice straw, corn, barley, wheat, coconut husks, and banana leaves, transforming them into protein [2][3][4][5][6]. Some species of the genus Pleurotus can grow and develop at temperatures between 10 and 28 °C, with substrate humidity between 50 and 75%.…”

The spent mushroom substrates of Hypsizigus marmoreus can be an effective component for growing the oyster mushroom Pleurotus ostreatus

“…Pleurotus ostreatus is the third most cultivated edible mushroom worldwide (Carvalho et al, 2012). In China, P. ostreatus is the most popular mushroom, and its cultivation is primarily dependent on cottonseed hulls.…”
