Fungal pretreatment of wheat straw for anaerobic digestion

Abstract : Recently, there has been a considerable interest for the production of renewable energy from lignocellulosic biomass which presents several advantages. It is, however, a technological challenge because of the difficulty to hydrolyze lignin contained in this biomass. This limitation can be overcome by pretreatments. Among them, low-cost fungal pretreatments are attractive. This study focuses on the selection of a fungal strain, in order to increase methane production from wheat straw. After a screening on 176 strains, thirteen were preselected and used to pretreat straw. BMP of those straws were measured. Compared to the control straw and considering pretreated VS, up to 43% more methane were obtained. Taking into account the dry weight loss observed during the pretreatment in non-optimized conditions, it was found up to 21% more methane compared to the control straw.
