This enzyme holds immense potential in applications such as biofuel production, textile processing, and bioremediation. Amidst the increasing interest in enzyme biotechnology, there is a growing emphasis on sourcing substrates that are both cost-effective and environmentally responsible. Aonla (Emblica officinalis), commonly known as Indian gooseberry, is a fruit widely cultivated for its nutritional and medicinal properties. The processing of Aonla generates significant quantities of pomace, a byproduct that is often underutilized or discarded. This study capitalizes on the underexplored potential of Aonla pomace as a substrate for endoglucanase production using the filamentous fungus Trichoderma harzianum. By harnessing the enzyme-producing capabilities of Trichoderma harzianum and utilizing Aonla pomace as a growth substrate, this research seeks to address multiple challenges simultaneously. Firstly, it aims to generate a sustainable and cost-effective platform for endoglucanase production, thereby reducing the reliance on conventional substrates. Secondly, it strives to contribute to the valorization of agricultural waste, aligning with the principles of circular economy and sustainable resource management. Lastly, the study aspires to advance enzyme biotechnology by uncovering new avenues for enzyme production and application. The utilization of Aonla pomace as a substrate holds the promise of yielding substantial quantities of endoglucanase while simultaneously addressing issues of waste management and resource utilization. Through a comprehensive exploration of culture conditions, optimization strategies, and enzyme yield enhancement, this study contributes to the growing body of knowledge in enzyme biotechnology and sets the stage for the sustainable utilization of agricultural byproducts in enzyme production.
