This study investigates the potential of using Aonla pomace, a byproduct of fruit processing, as a substrate for the
production of endoglucanase enzyme using Trichoderma harzianum. Endoglucanase is a crucial enzyme with
applications in various industries, including biofuel production and bioremediation. The study explores the
optimization of culture conditions, including pH, temperature, and fermentation time, to enhance endoglucanase
production. The findings demonstrate the efficacy of Aonla pomace as a cost-effective and sustainable substrate for
enzyme production, contributing to the valorization of agricultural waste and the advancement of enzyme
biotechnology.

key component of plant biomass. 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
div of knowledge in enzyme biotechnology and sets
the stage for the sustainable utilization of agricultural
byproducts in enzyme production.
METHOD
Aonla Pomace Preparation:
Collect Aonla pomace from fruit processing units and
air-dry to reduce moisture content.
Grind the dried pomace into a fine powder and store in
airtight containers.
Trichoderma harzianum Inoculum Preparation:
Cultivate Trichoderma harzianum on potato dextrose
agar (PDA) plates for 7 days at 28°C.
Harvest spores by scraping the surface of the plates
and suspending them in sterile saline solution.
Substrate Inoculation:
Prepare substrate medium using Aonla pomace
powder mixed with basal nutrient solution.
Adjust the pH of the medium to the optimal range for
Trichoderma harzianum growth.
Autoclave the substrate medium to ensure sterility.
Inoculate the substrate medium with Trichoderma
harzianum spore suspension.
Fermentation Conditions Optimization:
Conduct a series of experiments to optimize culture
conditions,
including
pH,
temperature,
and
fermentation time.
Monitor endoglucanase production by periodically
sampling the culture and assaying for enzyme activity.
