“…Cellulose produced from microorganisms such as bacterial cellulose (BC) possesses distinctive features, including high purity, biocompatibility, high crystallinity, moldability, biodegradability, excellent water retention capacity, high polymerization, substantial mechanical strength, non-toxicity, and ease of manipulation during biosynthesis. [3][4][5][6] In contrast, cellulose harvested from plants contains impurities such as lignin, pectin, and hemicellulose. 7 Therefore, BC emerges as a preferred alternative, finding applications in industrial waste treatment and biomedical sciences, including drug delivery systems, tissue engineering, wound dressings, medical implants, and transdermal applications.…”

Bacterial cellulose (BC) stands out as a prominent biopolymer of global importance, distinguished by its unique advantages over plant-derived cellulose. Strains such as Acetobacter xylinum, renowned for their proficient BC production, draw considerable attention in both commercial and biomedical areas. This research aimed to selectively isolate cellulose-producing bacteria with enhanced efficiency from a variety of fruit samples utilizing a cost-effective methodology. A total of 60 fruit samples were selected, and the assessment focused on 17 strains derived from rotten banana, red apple, green apple, and pineapple samples. The evaluation encompassed an examination of bacteriological traits and cellulose synthesis, with subsequent identification of strains achieved through DNA extraction and 16S rRNA PCR analysis. The experimental findings reveal cellulose-producing strains, including model A. Xylinum (KCCM 40407) obtained from the Pharmacy lab of COMSATS University Islamabad Abbottabad Campus, Pakistan, designated as number 2, serving as a control. Notably, strains isolated from deteriorated fruits (samples 1, 4, 8, 11, 12, and 15) demonstrated the capacity to produce soluble cellulose. A. Xylinum (model strain 2) was cultured under static conditions in HS media, demonstrating remarkable efficacy for cellulose sheet production. Subsequent characterization employing scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) unveiled a nano-fiber mat featuring multi-layered fibers. This eco-friendly approach has the potential for large-scale, high-quality cellulose production, applicable in biomedical and industrial fields. The research highlights an environmentally sustainable and economically viable method for cellulose production, presenting potential applicability across biomedical and industrial arenas on a significant scale.

“…Acetobacter xylinum is a Gram-negative bacterium that ferments actively at a pH range from 3 to 7 and a temperature range from 25℃ to 30℃ [2]. BC retains the fundamental structure of a fibril composed of β-1→4 glucan chains with the formula (C6H10O5)n held together by intra-and inter-hydrogen bonds [3,4]. Chen et al [5] stated that through biosynthesis, bacteria secrete glucan chains through pores arranged in regular lines along the long axes of the cell's cytomembrane.…”

Bacterial cellulose (BC) is produced by aerobic bacteria through oxidative fermentation in synthetic and non-synthetic mediums. Several mediums reported to be used as BC formation mediums are coconut water and soybean-boiled wastewater. Carbon sources are needed to optimize the BC formation process. Recent study has implemented a real-time image processing approach for monitoring BC formation. This study aimed to investigate the correlation between variables that influence the fermentation and to determine the kinetic model of BC formation using an image processing approach with the variation of carbon sources during the fermentation. The results showed that the correlation between fermentation time and thickness had the highest percentage for glucose, sucrose, and mannitol mediums. The kinetic observation of BC formation in the medium using glucose, sucrose, and mannitol followed the Gompertz model equation, with the medium using sucrose having the fastest rate of increase at the 44th hour, followed by the medium using mannitol at the 112th hour, and the medium using glucose at the 149th hour.
