Method for producing Euglena having high wax ester content

摘要

Provided is a method that is for producing Euglena having a high wax ester content and that is able to more effectively produce Euglena having a high wax ester content by restoring the fermentation efficiency of wax esters by adding a nutrient before anaerobic fermentation. The main configuration of the method is that there is at least a first step for aerobically cultivating the microalga Euglena in nitrogen-poor conditions, and a second step for holding the cells in an anaerobic state, and before the second step, a nutrient source is added to the culture liquid that has passed through the first step.
