Neutral and alkaline cellulases: Production, engineering, and applications.

Area of Science:

• Biotechnology
• Enzymology
• Microbiology

Background:

• Neutral and alkaline cellulases are vital industrial enzymes with broad applications.
• Most fungal cellulases function optimally at acidic pH, unlike those from species such as Humicola insolens.
• Growing demand across food, feed, textile, paper, and agricultural sectors necessitates these enzymes.

Purpose of the Study:

• To provide an overview of biotechnological research focused on neutral and alkaline cellulases.
• To highlight the importance of screening for novel cellulase-producing microorganisms.
• To address the increasing industrial demand for enzymes with neutral and alkaline pH optima.

Main Methods:

• Review of existing literature on neutral and alkaline cellulases.
• Analysis of screening strategies for identifying novel cellulase activities.
• Discussion of biotechnological approaches for enzyme discovery and engineering.

Main Results:

• Microbial screening is a primary method for obtaining novel cellulases.
• Certain fungi, like Humicola insolens, possess cellulases with non-acidic pH optima.
• The demand for neutral and alkaline cellulases is rapidly increasing, stimulating research.

Conclusions:

• Biotechnological research is essential for developing and engineering neutral and alkaline cellulases.
• Expanding applications in various industries drive the need for these enzymes.
• Continued screening and research are critical to meet the growing industrial demand.
