Industrial Biotechnology Based on Enzymes From Extreme Environments

Area of Science:

• Biotechnology and Biocatalysis
• Enzyme Engineering
• Microbial Ecology

Background:

• Biocatalysis is essential for a sustainable biobased economy, offering advantages like selectivity, reduced costs, and lower toxicity.
• Commercially available enzymes often exhibit limited stability under harsh industrial conditions (e.g., extreme pH, temperature, solvents).
• Extremophiles produce robust enzymes (extremozymes) with enhanced stability and activity under extreme environments.

Purpose of the Study:

• To provide an overview of extremozymes and their biotechnological applications.
• To highlight the challenges in accessing extremozymes due to cultivation difficulties.
• To present novel methods for studying extremozymes.

Main Methods:

• Review of existing literature on extremozymes and their industrial applications.
• Discussion of culture-independent techniques for studying extremophilic microorganisms.
• Exploration of genomic-based approaches for extremozyme discovery and characterization.

Main Results:

• Extremozymes possess unique properties making them ideal for demanding industrial processes.
• Current supply of extremozymes is insufficient to meet industrial demand.
• Culture-independent and genomic methods offer promising avenues for overcoming cultivation challenges and expanding the library of available extremozymes.

Conclusions:

• Extremozymes are critical for advancing green industrial processes.
• Further research and development in extremophile cultivation and molecular techniques are needed.
• Biotechnological applications of extremozymes are vast and continue to expand.
