Title:
METHOD AND SYSTEM FOR PRODUCING EUGLENA HAVING HIGH WAX ESTER CONTENT, METHOD AND SYSTEM FOR MANUFACTURING WAX ESTER OR BIOFUEL COMPOSITION, AND WAX ESTER FERMENTATION PROMOTER
Document Type and Number:
WIPO Patent Application WO/2022/220118
Kind Code:
A1
Abstract:
Provided are: a method and a system for producing Euglena having a high wax ester (WE) content, the method and system being improved so as to be capable of promoting WE fermentation more efficiently than in the prior art; a method and a system for manufacturing a WE or biofuel composition; and a WE fermentation promoter. The method for producing Euglena having a high WE content includes preparing Euglena, culturing the Euglena under aerobic conditions in the presence of sugar, applying a wax-ester-fermentation-promoting substance in an acidic environment, and maintaining a normal temperature for a prescribed length of time, the wax-ester-fermentation-promoting substance being one or more compounds selected from monovalent carboxylic acids having at least one of a keto group, an aldehyde group, and a hydroxy group per molecule and having 2-4 carbon atoms per molecule, and salts thereof.
