Bacterial Cellulose (BC) produced by numerous different techniques. The choice of a cultivation technique is strictly dependent on the biopolymer commercial destination. In the present study, BC was produced by G. hansenii PJK strain in shaking cultivation using the waste from beer fermentation broth (WBFB) as an alternative of chemically defined medium. The WBFB broth was treated with autolysis, hydrolysis and sonication.
The supernatant of the resulting autolysed, hydrolysed and sonicated product were analyzed for elemental composition. The untreated WBCB was used as control system. The production yield of untreated WBFB was higher than the autolysed, hydrolysed and sonicated. The amount of BC produced was 2.25, 0.612, 0.124 and 1.65 g/L after 168 h using untreated, autolysed, hydrolysed, and sonicated WBCB, respectively. Adding 1% glucose (commercial grade) to the untreated, autolysed, hydrolyzed and sonicated WBCB improved the production of bacterial cellulose, 2.996, 0.516, 0.92 and 1.98 g/L, respectively. The by-product, water soluble oligosaccharide (WSOS) produced during the cultivation of BC increased from 4.5 to 6.5 g/L after 168 h of cultivation.
