Heterologous expression systems for lipases: a review

Area of Science:

• Biotechnology and Biocatalysis
• Enzyme Engineering
• Microbial Fermentation

Background:

• Heterologous lipase production is crucial for improving bioprocess efficiency and reducing costs.
• Wider implementation of industrial lipase applications is a key objective.
• Microbial lipases are widely used in biocatalysis.

Purpose of the Study:

• To provide an overview of microbial expression systems for heterologous lipase overproduction.
• To analyze and compare prokaryotic (Escherichia coli) and eukaryotic (Saccharomyces cerevisiae, Pichia pastoris) systems.
• To present an overview of heterologous Candida rugosa and Rhizopus oryzae lipases.

Main Methods:

• Comparative analysis of microbial expression systems (E. coli, S. cerevisiae, P. pastoris).
• Evaluation of systems based on productivity, operational ease, and downstream processing.
• Review of heterologous lipase production using specific yeast hosts.

Main Results:

• Pichia pastoris demonstrated superior performance in heterologous lipase production.
• Comparison highlighted differences in productivity and processing among microbial systems.
• Candida rugosa and Rhizopus oryzae lipases were specifically examined.

Conclusions:

• Pichia pastoris is the most promising host for overproducing heterologous lipases.
• Optimized lipase production can significantly impact bioprocess economics and applications.
• Further research into microbial expression systems can unlock new biocatalytic potentials.
