Optimization of bacterial cellulose production in apple juice medium by using response surface methodology (RSM)
Published 2012“…Acetobacter xylinum is a type of acetic acid producing bacteria that can synthesis bacterial cellulose from carbohydrates.Bacterial cellulose that produced has high purity,high water holding capacity,good mechanical strength,elasticity,high crystallinity and high porosity compare to plant cellulose.This research was using apple juice as the high potential carbon sources to replace the pure carbon sources as the substrate for the synthesis of bacterial cellulose.The objective of this study was to optimize bacterial cellulose production in apple juice medium by using Response Surface Methodology (RSM).The research will be conducted by using 5 samples with difference temperature (28ºC, 29ºC, 30ºC, 31ºC and 32ºC) , 5 sample with difference in pH (4, 5, 6 ,7 and 8) and 5 sample with different medium concentration (60 %, 70%, 80%,90% and 100%).Each sample contains 100mL of medium in 250mL conical flask and incubated in incubator for 5 days.The bacterial cellulose film produced by Acetobacter Xylinum was treated with 1% Natrium Hydroxide (NaOH) for 1 day and then washed with Deionized water to neutralize the bacterial cellulose. …”

Fabrication of bio composite from bacterial cellulose/starch
Published 2012“…The objective of this study was to fabricate bio composite from starch, and bacterial cellulose.The research was conducted with 25 samples with difference composition of bacterial cellulose (BC)(0, 7, 14, 21 and 28)wt% and starch(3, 6, 9, 12 and 15)wt%.The bacterial cellulose film produced by Acetobacter xylinum was blend and mixed with starch, and glycerol.The film was characterized by using Universal Testing Machine,water absorption,Fourier Transform Infrared (FTIR),Thermo Gravimetric Analysis (TGA),Scanning Electron Microscopy (SEM) and Soil Burial Degradation,biodegradation by using Aspergillus niger.When the composition of starch and BC increased,the tensile strength and Tensile modulus was increased and the elongation at break was decreased.The absorption of water was increased proportionate with the increasing the composition of bacterial cellulose and starch.From the FTIR test,the bio composite was showed the present of hydroxyl group,C=O stretching(amide I),and C-O bonding.Besides that,TGA showed the thermal degradation of starch and cellulose occurs when the temperature arise to 280°C,leads to depolymerization and to the formation of 1,6-anhydroglucose-ß-Dglucopyranose.Moreover,the SEM analysis showed a smooth and homogenous structure of the film but when the composition of BC increased,the small mat fragments can be saw and the layered structure becomes clearer.The soil burial test and degradation by using Aspergillus niger indicated the degradation rate decreased as the bacterial cellulose content increased.As a conclusion,the film fabricated had a potential application in future to be used as food packaging material because as it had good mechanical properties and biodegradable.In order to improve the properties of bio composite,more research should be done to know the optimum composition of BC and starch should be used to produce the film.Besides that,the study about other alternative material or additive that can be added to the film also can be done to increase the mechanical properties and degradation time.…”
