- Cellulose produced by certain strains of bacteria is known as bacterial cellulose (BC). BC is a high value commodity with specific applications and usage. For BC production the proper medium conditions and availability of carbon sources are of prime importance. Usually glucose is used as a main carbon source for BC production. However, besides glucose some other additional carbon sources may also be used. Water soluble glucuronic acid oligomers (WSOS) are produced as a by-product during BC production. WSOS are rich source of utilizable carbon. Hence, in present study the BC production by Acetobacter sp. in shaking and static cultures was conducted using basal medium with different amounts of WSOS (0 ~ 4.0%). The pH, amounts of BC, WSOS and glucose were determined after five and ten days of cultivation. It was found that in basal media containing up to 2.0 % of WSOS the amount of BC was almost 1.5 to 2 times higher compared to control. However, media contained the higher amount of WSOS (more than 2.0%) showed a smaller glucose consumption, lower pH and a lower production of BC. The glucose amount in the media was almost diminished after five days of cultivation while the BC amount and pH of the medium was continuously increased with increase in cultivation time. It was observed that in all of the WSOS added media the reduction in WSOS amount occurred which indicated
its consumption during the process. From this whole study, it was inferred that using WSOS as an additional substrate worked as a nutrient after glucose exhaustion.
