Abstract

The present invention can: efficiently and readily produce glucose from microalgae that accumulate starch in their cells; and obtain ethanol. During a preparation step of the glucose production method, microalgae are prepared on which a saccharifying enzyme acts on starch accumulated inside the microalgae cells, without disrupting the cell walls. In a saccharification step, starch inside the cells is saccharified and glucose is generated, by adding a saccharifying enzyme to the microalgae without a disruption treatment. The ethanol production method has a step in which, after the saccharification step, the glucose undergoes alcoholic fermentation and ethanol is generated.
