Abstract

Microbial enzymes, produced by microorganisms such as bacteria, fungi, and algae, have emerged as indispensable biocatalysts across multiple industrial sectors due to their efficiency, versatility, and activity under diverse environmental conditions. This review aims to highlight the major industrial applications of microbial enzymes and synthesize evidence on their functional roles in contemporary bioprocesses. More than 80 published articles, textbooks, and newsletters were retrieved from reputable platforms, of which approximately 50 were selected for detailed analysis based on relevance and quality. The reviewed literature shows that enzymes now play critical roles in everyday life, with broad applications in medicine, pharmacy, environmental remediation, food processing, detergent manufacture, and energy production. In the detergent industry, amylases, lipases, and proteases are used to break down starch, fats, oils, and proteins, thereby enhancing washing efficiency. In the food sector, microbial enzymes support milk hydrolysis in cheese production, contributing to characteristic flavour development, and are widely employed in fruit juice clarification. In the energy sector, cellulases, xylanases, and lignin-degrading enzymes enable the breakdown of lignocellulosic substrates to release reducing sugars for biofuel production. Medically, L-asparaginase has been used in the treatment of leukaemia, while laccases are applied in the degradation of dyes and the reduction of chemical waste in environmental applications. The diversity of microbial sources allows these enzymes to function under extreme conditions, expanding their usability across varied industrial environments. Overall, the review concludes that microbial enzymes have extensive and growing industrial relevance, underscoring the need for continued research and development to optimize their production, stability, and application in sustainable biotechnological processes.

Abstract

Microbial proteases have attracted increasing attention as eco-friendly biocatalysts because of their broad functional versatility and advantages over proteases derived from plants and animals. This review examines the major sources, classification, production methods, and sectoral applications of microbial proteases. Produced by bacteria, actinomycetes, and fungi, microbial proteases are classified according to optimum pH range, catalytic mechanism, and site of action, and are commonly generated through submerged and solid-state fermentation. The review shows that these enzymes have diverse industrial applications in detergent, leather and tanning, food and dairy, brewing and beverage processing, and textile production. In medical and pharmaceutical contexts, microbial proteases are applied in wound debridement and healing, antimicrobial and antibiofilm activities, drug development, diagnostics, and therapeutic interventions. In agriculture, they support animal feed supplementation by improving protein digestion and function as biological control agents by disrupting pathogen attachment, penetration, and colonization of plant tissues. In the environmental sector, their applications include waste management, bioremediation, and the recycling of keratinous and other protein-rich wastes. Overall, this review underscores the wide-ranging utility of microbial proteases across industrial, medical, agricultural, and environmental sectors, highlighting their potential as sustainable biological agents for diverse biotechnological applications.
