Abstract

Bacterial cellulose (BC), a pure form of three-dimensional biopolymer is gaining extensive interest due to its unique physical and mechanical properties. The effects of different agitation conditions on BC synthesis by Acetobacter xylinum 0416 have been compared. Fermentations were carried out at 150 and 200 rpm using rotatory incubator shaker and rotatory shaker in a constant temperature room of 30 ºC. Matured coconut water was used as a sustainable medium due to its low cost and availability. The medium was adjusted to pH 4.5 or pH 5.5 and BC pellets were collected after 7 days of fermentation. The constant temperature room appeared to has fluctuate degree of heat during fermentation up to 37 ºC and suppressed the BC production. In rotatory incubator shaker, the BC produced have insignificant different in comparison to pH and rotation speed. These results indicate that matured coconut water has potential as the carbon source for BC synthesis and optimization of fermentation temperature is important to produce enormous yield of BC.
