Production of Free Sugars by Enzymatic Hydrolysis of Dictyota Dichotoma

Abstract

It is well-known that brown macroalgae can be used as a source of valuable sugars with different biological activities, but its polymeric macrostructures should be hydrolyzed for obtaining an acceptable yield. This study deals with the production of free sugars by the enzymatic hydrolysis of optimized biologically pretreated brown seaweed. The biological pretreatment was carried out using solid-state fermentation (SSF) with a white root fungus species (Aspergillus awamori). For this purpose, different temperature growth conditions (30ºC and 50ºC) and inoculum concentrations (10⁶; 10⁷ and 10⁸ spores/g of dried solid) were tested for 20 days of the SSF process.
