Banana Peel as a sustainable substrate for microbial enzyme production: A review
Authors
Kavya G, Chandrakant S Karigar
Abstract
Banana peel, a readily available
lignocellulosic agro waste, has gained increasing attention as a low-cost and
environmentally sustainable substrate for microbial enzyme production. This
review emphasizes current scientific advances in utilizing banana peel for the
biosynthesis of industrially significant enzymes, including pectinase,
cellulase, amylase, lipase, catalase, protease, peroxidase and L-asparaginase,
through fungal and bacterial fermentation systems. The influence of banana
varietal composition, ripeness stage, and substrate pretreatment on enzyme
yield, along with comparing fermentation methods such as solid-state and
submerged fermentation, is assessed. Prominent microbial strains—including Aspergillus
niger, A. japonicus, Trichoderma reesei, Paenibacillus
lactis, and Yarrowia phangngaensis—are highlighted for their enzyme
efficiency. Industrial applications are discussed in the context of biofuel
generation, food processing, textile treatment, and environmental remediation.
Despite scale-up limitations and variability in substrate composition,
integrating banana peel bioprocessing with circular bioeconomy frameworks can
transform food waste into valuable bioproducts, contributing to sustainable
development goals (SDGs).
