Abstract

Objectives: Urban wastes that contain lignocellulosic substances are potential substrates for mushroom cultivation. The study tested selected urban wastes as substrates for the cultivation of Pleurotus djamor, P. sajor caju, and P. florida. Methods: Three different urban wastes (white used paper, banana peels and mixture of leaf litters) and their combinations were used in the study with sawdust served as the control. Percentage of mycelial growth, colonization period, and number of fruiting bodies, cap diameter, stipe length, total yield, and size of the mushroom and biological efficiency of the substrates used were assessed to determine the effects on growth and yield. Findings: Results revealed that the rapid mycelial colonization where the highest mushroom yield and percentage biological efficiency were observed from UP100 for P.djamor, UP75 for P. sajor caju and BP25 for P. florida and the lowest yield were obtained from those in combinations of leaf litters and banana peels. Novelty: Protocol obtained from this research can be applied and implemented in an urban setting where there are no available agricultural wastes rich in lignocellulosic substances can be used in the cultivation of edible mushroom such as P. djamor, P. sajor caju and P. florida. Keywords: Oyster mushroom; growth performance; lignocellulose; biological efficiency; mushroom yield

Highlights

Mushroom contains ample amount of proteins, vitamins, minerals, dietary fiber and variety of secondary metabolites [1] and are receiving significant attention due to their exceptional medicinal value; curative and prophylactic especially in many diseases such as high blood pressure, asthma, respiratory tracts infection, anemia, hepatitis, cancer, tumor, and many others [2].Growing mushrooms in the Philippines is economically feasible
The urban wastes used as substrates in this study such as: used paper (UP), banana peels (BP) and leaf litters (LL) and the sawdust (S) as controlled treatment, contain cellulose, hemicellulose and lignin
Rapid mycelial colonization was observed in UP100 which was fully completed on the 3rd week for P. florida and P. sajor caju, and nearly 4th week for P. djamor

Summary

Introduction

Mushroom contains ample amount of proteins, vitamins, minerals, dietary fiber and variety of secondary metabolites [1] and are receiving significant attention due to their exceptional medicinal value; curative and prophylactic especially in many diseases such as high blood pressure, asthma, respiratory tracts infection, anemia, hepatitis, cancer, tumor, and many others [2].Growing mushrooms in the Philippines is economically feasible. The large number of agricultural wastes and warm climatic conditions in the country provide tremendous opportunity for mushroom cultivation. Mushrooms are grown on Alvarez & Bautista / Indian Journal of Science and Technology 2021;14(3):259269 pasteurized agricultural wastes such as rice straw, rice husk, wheat, banana leaves, etc., and can be cultivated on large variety of substrates which contain lignin, cellulose and hemicelluose. Mushroom mycelia have the capability to bioconvert the lignocellulosic substances effectively and can colonize on various residues as its substrates. This ability of the mushroom makes them easy to be cultivated using agro- and industrial wastes [3,4]
