Lignocellulosic biomasses pretreatment by filamentous fungi for biofuels

This fungal pretreatment aims to degrade the  hemilignocellulosic network to facilitate the subsequent stages of hydrolysis, thanks to a better accessibility of carbohydrate degrading enzymes to their substrate.

INRA within its join research unit BBF has developed a bioenergy process comprising: the fungal pretreatment of lignocellulosic biomass in solid state by P.brumalis, the hydrolysis, and fermentation of the biomass. This fungal pretreatment aims to degrade the  hemilignocellulosic network to facilitate the subsequent stages of hydrolysis, thanks to a better accessibility of carbohydrate degrading enzymes to their substrate.

Addvantages:

The process improves the enzymatic hydrolysis of lignocellulosic biomasses; The process increases biogas production; The process allows 30 to 50% of delignification (wheat straw); The used strain is wild, lignin selective with a low cellulose and hemicellulose degradation; The process is energetically inexpensive and environmentally friendly
