Potential of lignocellulosic residues from coconut, fique, and sugar cane as substrates for pleurotus and ganoderma in the development of biomaterials

Abstract

In this work, three lignocellulosic residues, coconut fiber, sugarcane bagasse, and fique bagasse, were used as a carbon source for fungal colonization had been proposed to form a composite material. The lignocellulosic residues presented a high percentage of carbon. The lignocellulosic residues had been conditioned and characterized morphologically. The particle sizes chosen were 16 and 50 sieves. The mycelial growth kinetics of the fungi had been evaluated in the residues, where a higher growth rate was observed in the medium enriched with coconut fiber and lower in those containing bagasse. When studying these intrinsic factors, it was observed that an inadequate carbon-nitrogen (C/N) ratio affected mycelial growth. This method of obtaining biomaterials is a promising alternative to lignocellulosic substrates as substrates for fungi with delignification capacity.

Physico-chemical characterization of lignocellulosic wastes used in the cultivation of Pleurotus ostreatus

“…Analyzing the pH, all residues and substrates showed acidic values, ranging from 6.00 to 6.24 for the residues and from 6.59 to 6.69 for initial substrates (Table 1). Due to the presence of short-chain fatty acids, lignocellulosic residues commonly have acidic pH (Xiros;Shahab;Studer, 2019;Solanilla-Duque;Salazar-Sánchez;Herrera, 2021). After cultivation, a decrease in pH values was observed for all (Table 1).…”

Abating the deterioration of environmental quality: Valorization of agricultural waste – An introduction

“…Abdel-Moemin and Abdel-Rahman (2022) gave a different perspective on the circular utilization of agricultural waste in the fish industry and the potential development of sustainable products from the fish bone waste. Solanilla-Duque et al (2022) reported on the potential of using lignocellulosic residues from coconut, fique and sugar cane as substrates for the growth of Pleurotus and Ganoderma in the development of biomaterials. The mycelial growth kinetics of the fungi had been evaluated in the residues, where a higher growth rate was observed in the medium enriched with coconut fiber and lower in those containing bagasse.…”
