Abstract: The present invention relates to a method for saccharifying marine algae extruded by a high pressure extrusion process by pretreatment and, more particularly, an eco-friendly method for saccharifying marine algae without an acidic or alkaline material by pretreating marine algae through a high pressure extrusion process and a process selected among a microwave process, an ultrasonic process, an ultra-high pressure process, and a homogenization process; and treating the marine algae with saccharifying enzymes. Polysaccharides forming the marine algae, such as cellulose, hemicellulose, starch, and conjugated saccharides which are non-biodegradable polymers are hybridized with high saccharification efficiency by the eco-friendly pretreatment process using water.

Abstract: PURPOSE: A method for saccharification of biomass such as marine algae or agricultural by-products is provided to enable hydrolysis of non-degradable polymers with a high saccharifying efficiency. CONSTITUTION: A method for saccharification of marine algae or agricultural by-products comprises: a step of homogenizing and crushing the marine algae or agricultural by-products; and a step of extruding the crushed marine algae or agricultural by-products through a pipe with a diameter of 10-500 um. The marine algae or agricultural by-products are homogenized by rotating at 10,000-50,000 rpm using a homogenizer. The method further comprises a step of extracting the extruded marine algae or agricultural by-products by hot water extraction or high pressure liquefaction and treating with an enzyme. The enzyme is cellulase, amyloglucosidase, beta-agarase, beta-galatosidase, beta-glucosidase, endo-1,4-beta-glucanase, alpha-amylase, or beta-amylase. The marine algae are red algae, brown algae, green algae, or microalgae.
