Title:
METHOD FOR PRODUCING MICROALGAE OF WHICH AUTOPHAGY IS INHIBITED AND AMOUNTS OF STARCH AND LIPIDS ARE INCREASED
Document Type and Number:
WIPO Patent Application WO/2017/039344
Kind Code:
A1
Abstract:
The present invention relates to: a method for producing microalgae of which the amounts of starch and lipids are increased, comprising a step of inhibiting autophagy while culturing the microalgae under an autophagy inducing condition; microalgae produced by the method such that the amounts of intracellular starch and lipids are increased; biomass including the microalgae; a method for producing biodiesel by using the biomass; and biodiesel produced by the method. When using the method of the present invention, microalgae, of which the amounts of intracellular starch and lipids are increased, can be produced and the produced microalgae, of which the amounts of intracellular starch and lipids are increased, can be used as biomass for producing biodiesel, and thus the microalgae can be useful in the economical production of biodiesel.
