Suryani Kamarudin, et al. Fig.4 shows the productivity of BC in different fermentation media, which is proportional to the dry weight of BC. The highest productivity was obtained by M1 at day-6 of incubation at 0.044 g l -1 day -1 . This means the M1 medium formulation shows excellent productivity compared to the other media. Hestrin and Schramm (1954) and Forng et al. (1989) reported that although various undefined and synthetic media have been developed for A. xylinum, more cellulose has been produced by the undefined medium compared to the synthetic medium. M1 medium formulation serves the most complex composition compared to the others, which covers the requirements for BC production. CONCLUSION Based on the results obtained in this experiment, it can be concluded that medium formulation M1 CWHSM can be a potential medium for production of BC. The advantage of CWHSM is that the medium substrate is easy to procure, as it can be locally sourced and is inexpensive as well. The use of coconut water, without any pre-treatment or hydrolysis, makes it very effective from the economic point of view. In addition, it does not involve toxic and hazardous materials in producing BC, which is excellent and suitable for safe environments such as medical and cosmetic applications. Moreover, the static surface culture fermentation also requires a low cost operation and is easy to perform.
