Chitin and chitosan are copolymers consisting of units N-acetil-D-glucosamine and D-glucosamine in varying proportions, with the first type of these units are predominant in the case of chitin, while chitosan is composed predominantly of D-glucosamine units. In this investigation was compared the growth, chitin and chitosan production by Rhizopus arrhizus and Cunninghamella elegans using different amount of carbon and nitrogen source, represented by the concentrations of D-glucose, thiamine and L-asparagine. These parameters were varied symmetrically around the central point according to the 2³ factorial design. The extraction process involved deproteinization using 1 M NaOH solution, followed by treatment with acetic acid 2% solution. Different carbon and nitrogen concentrations of the culture medium influenced the biomass, chitin and chitosan yields, consequently, these independent variables can be manipulated during the fermentation to possibility the optimal production of these biopolymers. The best yield of chitin by R. arrhizus (135.17 mg/g) was inferior to C. elegans (235 mg/g). However, the higher chitosan production by R. arrhizus (68.17 mg/g) was superior C. elegans (46.18 mg/g).
