“…Nakayama et al (2004) for the first time reported cellulose-polymer nanocomposite hydrogels composed of bacterial cellulose (BC) and gelatin. Bacterial cellulose is biosynthesized by microorganisms, and displays unique properties, including high mechanical strength, high water absorption capacity, high crystallinity, and an ultra-fine and highly pure fiber (10-100 nm) network structure (Vandamme et al, 1998). By immersing BC gel in aqueous gelatin solution followed by cross-linking with N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride, high mechanical strength doublenetwork (DN) nanocomposite hydrogels were prepared.…”

“…To be one excellent material for industrial application, BC especially showed great potential as water adsorbent for its great capacity for water absorption [9,10]. However, because of its poor dissolution properties and processing difficulties, BC's application as water adsorbent for water conservation is still limited [9,[11][12][13][14][15][16][17].…”

To evaluate the possibility of Bacterial cellulose/Inorganic Gel of Bentonite (BC/IGB) composite production using in situ method, the BC/IGB composite was successfully produced by in situ modification of BC in both HS medium and corncob hydrolysate. The results showed that the BC/IGB composite obtained in HS medium (one classical medium for BC production) had a higher water holding capacity, but the water retention capacity of the BC/IGB composite obtained in corncob hydrolysate was better. The performance of BC/IGB composite depended on the environment of in situ modification. Using different media showed significant influence on the sugar utilization and BC yield. In addition, BC/IGB composite produced by in situ method was compared with that produced by ex situ method, and the results shows that water holding capacity of BC/IGB composite obtained through in situ method was better. XRD results showed the crystallinity of BC/IGB composite related little to its performance as water absorbent. Overall, in situ modification is appropriate for further production of BC composite and other clay materials.

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 °C 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.Keywords: bacterial cellulose, matured coconut water, fermentation, agitation speed Abstrak Selulosa bakteria (SB) iaitu sejenis tiga-dimensi biopolimer sedang mendapat tumpuan yang meluas disebabkan oleh sifat fizikal dan mekanikalnya yang unik. Kesan goncangan yang berbeza terhadap sintesis SB oleh bakteria Acetobacter xylinum 0416 telah dibandingkan. Proses fermentasi telah dilakukan pada kelajuan 150 rpm dan 200 rpm menggunakan inkubator penggoncang berputar yang tertutup dan inkubator penggoncang berputar terbuka yang terletak di dalam bilik malar pada suhu tetap 30 °C. Air kelapa tua digunakan sebagai medium mapan kerana mudah diperoleh pada kos yang rendah. Media ini dilaraskan pada pH 4.5 atau pH 5.5 dan pelet BS dikumpulkan selepas 7 hari fermentasi. Suhu bilik malar didapati berubah-ubah sepanjang fermentasi sehingga meningkat kepada 37 °C dan membantutkan penghasilan SB. Melalui penggunaan inkubator penggoncang berputar yang tertutup, SB yang terhasil mempunyai perbezaan kuantiti yang tidak signifikan dari segi pH dan kelajuan goncangan. Keputusan ini menunjukkan air kelapa tua mempunyai potensi sebagai sumber karbon bagi sintesis SB dan pengoptimuman suhu fermentasi adalah penting untuk menghasilkan SB yang banyak.Kata kunci: bakteria selulosa, air kelapa tua, fermentasi, kelajuan goncangan.
