Description: Biomass char may be seen as a value-added product with respect to raw biomass due to improved properties, such as the potential resistance to biodegradation. This resistance to biodegradation property might be of interest for two practical biomass char applications, i.e.: bioenergy, for the storage of the solid energy feedstock and biochar, as a soil amendment where carbon stability of the biomaterial would be a major asset. This research was conducted in a perspective of a step taken along the development of a laboratory method to assess the microbial degradation resistance of biomass char; especially low severity char pyrolysis production such as mild pyrolysis (torrefaction). Along this research, corn residues and charred corn residues, which were produced by mild pyrolysis at 300 ? 10 ?C for 15 minutes at this temperature, were both inoculated with a consortium of Trichoderma reesei fungi and Candida yeast in aqueous conditions at 25 ?C into 250 mL individual flasks. Degradation of the inoculated samples were followed with respect to non-inoculated samples. Incubation time effect was studied for 7, 14 and 21 days incubation period. Biodegradation of biomaterials was followed by dry mass balance, by analyzing protein content within soluble content, by elemental analysis as well as quantifying Candida yeast development along community forming units method on potato dextrose agar (PDA) and tryptone soya agar (TSA). Significant differences were observed among samples analyses and are presented and discussed along this study.
