Biodelignification of agricultural and forest wastes: Effect on anaerobic digestion
Four lignocellulosic wastes (wood fiber, grass, corn stover and wheat straw) were treated with the ligninolytic fungus Phanerochaete flavido-alba to improve their anaerobic digestion. After 21 days solid substrate culture, lignin content was depleted in all materials by fungus in a range between...

Summary: | Four lignocellulosic wastes (wood fiber, grass, corn stover and wheat straw) were treated
with the ligninolytic fungus Phanerochaete flavido-alba to improve their anaerobic digestion.
After 21 days solid substrate culture, lignin content was depleted in all materials by fungus
in a range between 5 and 20%, but cellulose and hemicellulose were also biodegraded.
Anaerobic biodegradability of corn stover, grass and wood fiber increased as a consequence
of fungal treatment. Biogas production was enhanced only in wood fiber. Fungal delignified
wood fiber produced 124 NL biogas kg 1 dry wood fiber with a 64% methane, after 21 days
anaerobic digestion; while non-inoculated controls did not produce any biogas. Predigestion
of agricultural wastes (corn stover, grass and wheat straw) before biodelignification
treatment failed to improve subsequent biogas production. |
