“…During fermentation, the pH of culture medium will decrease throughout the process [13]. Kongruang [14] and Suwannapinunt et al [15] reported that acetic acid was produced during the synthesis of bacterial cellulose as a by-product and reduces the pH of the culture medium, while other researchers reported the presence of gluconic acid in the culture medium due to the excessive supply of glucose as the main factor in the pH reduction [5,[16][17][18].…”

Bacterial cellulose demonstrates unique properties including high mechanical strength, crystallinity and water retention ability that are suitable for industrial applications, such as food, paper manufacturing and pharmaceutical. In this study, Acetobacter xylinum 0416 was cultured in a designed 10-L Rotary Discs Reactor (RDR) to produce bacterial cellulose. The effects of different pH in the range of 3.5-7.5 on the bacterial cellulose production and the bacterial growth were investigated. The highest yield was obtained at pH 5.0 with a total dried weight of 28.3 g, while the lowest yield was obtained at pH 3.5 with a total dried weight of 4.7 g. Results also showed that the dried weight of bacterial cellulose was 60 % higher when the pH of the medium was controlled during the experiments compared with uncontrolled pH. In addition, A. xylinum 0416 growth decreased to around 30 % when pH value dropped from 5.05 to 3.56. The results also proved that the formation of acetic acid as a byproduct caused the pH to drop during fermentation process in 10-L RDR.

“…BC has advantages among other cellulose in mechanical strength, crystallinity, nanofibril structure, purity, and biocompatibility [59]. BC has the potential to be used in biomedical [59], audio membrane [60], electronic paper [61], and biocomposites [22,62]. With this many potentials, it does not close the possibility of using BC as an environmentally friendly scrubber.…”

Scrubber is widely used in various products, such as cosmetics, facial cleansers, and soaps. The use of scrubber releasing 209.7 trillion microplastics would harm the environment due to lack of process in treatment facilities. Efforts to substitute plastic-based scrubbers with more environmentally friendly materials need to be made. In previous studies, substitution scrubber with grape seeds has been done but has a low viscosity. This problem may be solved by using bacterial cellulose (BC) in the manufacture of bio-scrubbers. Several methods are currently being investigated to produce bacterial cellulose microparticles, such as mechanical methods using high-pressure homogenizer (HPH), acid hydrolysis, microbial hydrolysis, hydrogel fiber cultivation, microfluidic process, and ultrasonication. This review recommends the manufacture of bacterial cellulose microparticles by ultrasonication method. The recommendation is based on the literature study that has been carried out. The ultrasonication method has more advantages than other methods. It does not use solvents that pollute the environment and increasing the number of bacterial cellulose microparticles. The synthesis of bio-scrubber from bacterial cellulose ends with the drying process of bacterial cellulose microparticles. This review recommends the ambient pressure drying method. The ambient pressure drying method can produce bio-scrubber with high crystallinity, high mechanical properties, and transparency.

“…Beyond the applications in food industry, as a natural biomass, bacterial cellulose shows excellent biodegradability and biocompatibility and thus has great application potential in the biomedical field . Owing to the high tensile strength of a bacterial cellulose single fiber, that is, almost the same as steel and Kevlar, as well as the robust 3D network structure, bacterial cellulose is well suited for use as a reinforcing agent for paper and polymer composites . The high modulus of elasticity and large internal loss factor of bacterial cellulose make it an attractive candidate for headphone and loudspeaker membranes .…”

Carbon aerogels that are typically prepared using sol-gel chemistry have unique three dimensional networks of interconnected nanometer-sized particles and thus exhibit many fascinating physical properties and great application potentials in widespread fields. To boost the practical applications, it is necessary to develop efficient and low-cost methods to produce high-performance carbon aerogels on a large-scale, preferably in a sustainable way. In 2012, two new classes of aerogels consisting of carbon-nanofiber (CNF) networks were prepared from biomass-derived precursors by chemosynthesis (i.e. template-directed hydrothermal carbonization of carbohydrate) and biosynthesis (i.e. use of bacterial cellulose as precursor), respectively. This Review gives a critical overview of this emerging and rapidly developing field, focusing on the synthetic strategies of the carbon-nanofiber aerogels and their outstanding physical properties. We also discuss the multifunctional application potentials of the two sorts of carbon aerogels and their nanocomposites, and highlight the challenges and future opportunities in this field.
