PURPOSE: A method for preparing polyhydroxyalkanoate from a saccharified solution of Hydrodictyaceae algal biomass is provided to cheaply saccharify and to produce biochemical products. CONSTITUTION: A method for preparing polyhydroxyalkyanoate from a saccharified solution of Hydrodictyaceae algal biomass comprises a step of saccharifying Hydrodictyaceae algal biomass and preparing a saccharified solution containing monosaccharides. The Hydrodictyaceae algae are selected from the group consisting of Hydrodictyon sp., Pediastrum sp., and Sorastrum sp. The saccharification is performed using a hydrolysis catalyst, a polysaccharide decomposition enzyme, or a mixture thereof. The polysaccharide decomposition enzyme is selected from the group consisting of cellulase, beta-glucosidase, beta-agarase, betas-gallactosidase, endo-1,4-beta-glucanase, alpha-amylase, beta-amylase, amyloglucosidase, alpha-D-glucosidase, beta-D-glucosidase, sucrase, maltase, isomaltase, and lactase.
