Kinetic Study of a Bacterial Cellulose Production by Komagataeibacter Rhaeticus Using Coffee Grounds and Sugarcane Molasses

Biotechnology can be used to convert waste into valuable products. In this context, there is bacterial cellulose (BC), a natural biopolymer that transformed several useful materials, but its production limited due the high cost of culture media for industrialization. work, BC was produced from bacteria Komagataeibacter rhaeticus, using coffee grounds, sugarcane molasses and ethanol. The experiments were carried out under static conditions. products collected every 48 h, with total period 240 h. maximum (11.08 g.L-1) obtained in medium supplemented powder, hydrolyzed cane addition 1% (v/v) results show use different carbon sources evaluated by-products are viable alternatives reducing costs production.
