Microbial Production, Extraction, and Quantitative Analysis of Isoprenoids

Area of Science:

• Biotechnology
• Natural Product Chemistry
• Metabolic Engineering

Background:

• Isoprenoids (terpenoids) are a vast class of natural products with significant biological roles and industrial applications.
• Their natural production in plants is often limited, necessitating alternative production strategies.
• Microbial biosynthesis offers a promising route for scalable and economical isoprenoid production.

Purpose of the Study:

• To provide detailed laboratory protocols for microbial isoprenoid production.
• To enable the efficient cultivation, extraction, and quantification of various isoprenoid classes.
• To facilitate the use of engineered or naturally producing microbes, focusing on yeast and cyanobacteria.

Main Methods:

• Lab-scale cultivation of microbial systems (yeast, cyanobacteria) for isoprenoid biosynthesis.
• Extraction protocols for isolating isoprenoids from microbial cultures.
• High-performance liquid chromatography (HPLC) for quantification of diverse isoprenoid compounds.

Main Results:

• Established protocols for producing and analyzing C10 to C40 isoprenoids.
• Demonstrated the adaptability of protocols for different microbial hosts.
• Provided a framework for optimizing microbial isoprenoid yields.

Conclusions:

• Microbial systems, particularly yeast and cyanobacteria, are effective platforms for isoprenoid production.
• The presented protocols offer a standardized approach for lab-scale isoprenoid biosynthesis and analysis.
• This work supports the broader goal of making valuable isoprenoids more accessible for industrial applications.
