Single cell oils--have they a biotechnological future?

Area of Science:

• Biotechnology
• Microbiology
• Lipid Science

Background:

• Microorganisms are known producers of edible oils.
• Biotechnological applications are currently limited to high-value products.
• A recent attempt to produce cocoa-butter equivalents using yeast failed due to market prices, not production capability.

Purpose of the Study:

• To explore the potential of microbial biotechnology for producing polyunsaturated fatty acids (PUFAs) and other unusual lipids.
• To identify microorganisms capable of synthesizing specific fatty acid profiles for commercial applications.
• To assess the feasibility of using microbial sources for novel lipid production.

Main Methods:

• Investigated bacteria, fungi, and algae for PUFA production.
• Analyzed the fatty acid profiles of microbial oils.
• Examined the potential for producing prostaglandin precursors and other unique lipids.

Main Results:

• Microorganisms show promise for producing polyunsaturated fatty acids (PUFAs) of both n-6 and n-3 series.
• Microbial PUFA oils often lack other PUFAs, simplifying purification.
• Certain microbes can produce prostaglandin precursors, prostaglandins, cerebroside lipids, and other unusual lipids.

Conclusions:

• Microbial production of specific PUFAs presents a viable biotechnological opportunity.
• The unique lipid profiles of microorganisms offer potential for novel product development.
• Further research into microbial lipid synthesis can unlock new applications in various industries.
