Description Consortia were developed for the treatment of
corncobs for use as a feedstock in a biogas fermentor. The
treatment of corncobs with xylanolytic consortia enhanced
the production of methane and biogas. All five consortia
developed produced the maximum biogas and methane at
a 6% loading rate and 20 days hydraulic retention time
(HRT). The maximum biogas yield of 0.59m3/kg volatile
solids (VS) with a methane content of 62% was produced
with the KK-10 consortium. This was apparently due to a
maximum hemicellulose degradation of 88%.
most abundant polysaccharide of plant origin available
in nature after cellulose is xylan, and several hydrolytic
enzymes are needed for the degradation of branched
xylan.12 Xylanolytic enzymes have the potential to be used
in hydrolyzing xylan-containing wastes for the production
of sugar, alcohol, and other products, to release enzymatically free pentose sugars in animal feeds, and to dissolve cellulose-linked hemicellulose for rayon production and the biobleaching of paper pulp. Anaerobic digestion by xylanolytic consortia was selected for the utilization of corncob waste for methane generation. This paper describes the experiments carried out to optimize the various nutritional and operational parameters for the maximum production of methane from xylanolytic consortia utilizing corncobs.
