These raw materials are relatively

These raw materials are relatively inexpensive, abundant and based on agricultural residuesand wastewater (Charreau et al., 2013). Most of these agriculturalresidues/feedstocks are hydrolyzed using acid or by using pretreatment and enzymatic hydrolysis for BC production (Guo et al., 2013).The BC culture medium for these studies also requires other nutrients such as yeast extract, tryptone, peptone, etc. also shown in Table 1. In addition, these alternative carbon sources contain highamounts of sugars compared to wood hot water extract.
