ABSTRACT Oyster mushrooms classified under the Pleurotus species are renowned for their role as primary decomposers and their ability to grow on a variety of substrates. Their effectiveness in biotechnological applications is highlighted by their use in recycling lignocellulosic organic waste. In India, tea is one of the most popular beverages and the market for tea products is growing rapidly. Tea waste which consists of cellulose (28–30%), hemicellulose (10–20%), and lignin (28–30%), offers a unique substrate for mushroom cultivation. This composition contrasts with that of other common mushroom-growing substrates like rice straw and sawdust. Rice straw contains cellulose (32–39%), hemicellulose (23–24%) and lignin (18–36%) while hardwood sawdust includes cellulose (40–55%), hemicellulose (24–40%) and lignin (18–25%).The DHT-22, also known as the AM2302, is a digital-output sensor that measures relative humidity and temperature. It utilizes a capacitiv...
