“…Lin et al [ 210 ] cultivated shiitake on woodchips and produced biogas by anaerobic digestion (AD) of SMS; at the end, around 53–57% (dry mass) of the substrate was solid leftover. Since the AD process consumes mostly carbohydrates [ 211 , 212 ], the leftovers are expected to have a relatively high content of lignin, a component with a high calorific value. Therefore, using the leftovers as a solid fuel for a self-supporting heating system could be meaningful.…”

Spent mushroom substrate (SMS) is the residual biomass generated after harvesting the fruitbodies of edible/medicinal fungi. Disposal of SMS, the main by-product of the mushroom cultivation process, often leads to serious environmental problems and is financially demanding. Efficient recycling and valorization of SMS are crucial for the sustainable development of the mushroom industry in the frame of the circular economy principles. The physical properties and chemical composition of SMS are a solid fundament for developing several applications, and recent literature shows an increasing research interest in exploiting that inherent potential. This review provides a thorough outlook on SMS exploitation possibilities and discusses critically recent findings related to specific applications in plant and mushroom cultivation, animal husbandry, and recovery of enzymes and bioactive compounds.

Entre los factores bióticos con habilidad para degradar la madera se encuentran los hongos xilófagos. Estos organismos se clasifican según las preferencias de sustrato de crecimiento y sus patrones de descomposición de la madera; sobresaliendo aquellos causantes de las podredumbres blanca y parda o marrón. La principal diferencia entre ellos reside en su mecanismo de degradación, pues la podredumbre blanca se basa en la hidrólisis enzimática; mientras que la podredumbre marrón realiza una modificación de la lignina mediante la química de Fenton y especies reactivas de oxígeno, para llevar a cabo una posterior hidrólisis enzimática. Tanto la pudrición blanca como la parda poseen valiosas aplicaciones biotecnológicas en cuanto a biorremediación. Entre ellas sobresalen el manejo de desechos, degradación de químicos persistentes en el ambiente, remoción de metales tóxicos, entre otros.

“…20 Finally, some minerals and heavy metals have been identified in the filtrates of fungal pretreated lignocellulosic residues that could act synergistically as trace elements on the anaerobic digestion stage. 21 This work evaluates a sequential process of lignocellulosic biomass applying SSF by fungi and SSAD considering that it could be a good alternative, due to the similarity between operational variables. In addition, this strategy allows the production of several by-products, such as biogas, ligninolytic enzymes and fertilizer.…”

BACKGROUND Lignocellulosic residue valorization is a relevant topic because the study of residue and waste recycling is essential for circular economy development. This area is focused on treatment development for value‐added compound production. This work presents a sequential process of solid‐state fermentation (SSF) by white‐rot fungi (WRF) followed by solid substrate anaerobic digestion (SSAD) with the objective of producing bioenergy and other ancillary product. The agricultural residue from common bean pod (Phaseolus vulgaris) has never been studied for the purpose of a biorefinery concept. In addition, the intermediate stage for enzyme recovery was evaluated, comparing two extractants on their enzyme stability and effectiveness effect and the subsequence SSAD process effect. RESULTS Trametes versicolor produced the highest enzymatic activity of laccase, reaching 1588 U L−1 at 12 days of SSF. Under this condition, both extractants showed excellent enzymatic stability at 17 °C, but only the enzymes recovered with phosphate buffer were capable of the micropollutant degradation. SSF caused an increase in biodegradability of the lignocellulosic residue, providing an increase in biogas yield between 0% and 75.5%; however, high volatile solids consumption during fungal growth decreased the amount of biogas per volatile solid mass before treatment. CONCLUSION Common bean pods were successfully valorized through the sequential process by SSF of the WRF T. versicolor and SSAD, producing enzymes as a value‐added product and biogas from the remaining solids. The enzymes produced were stable and effective for micropollutant degradation when they were recovered with phosphate buffer. © 2021 Society of Chemical Industry (SCI).
