Summary: By UV-induced random mutagenesis, 60 mutants of Gluconacetobacter xylinus ATCC 53524 were obtained, among which the cellulose production of LYP25 and LYP23 increased by 46.4% and 44.9% respectively. Fermentation profiling showed that LYP25 exhibited 13.8% higher glucose consumption and 41.0% higher cellulose production compared to the control strain. The physicochemical properties of LYP25-derived bacterial cellulose were similar to those of the control strain, indicating that this mutant strain has the potential to be a promising producer of bacterial cellulose in the bio-industry.

Summary: Cellulose plays a crucial role in bacterial biofilms by preventing dehydration and mechanical disruption. Through cryo-electron tomography and focused-ion-beam milling, researchers observed the process of cellulose synthesis in Gluconacetobacter bacteria, revealing a novel cytoskeletal structure named the cortical belt. The study provides insights into the cell-guided process of crystalline cellulose synthesis in Gluconacetobacter genus.

Summary: The unique nanostructure of bacterial cellulose (BC) allows for diverse applications but the high production cost necessitates more cost-effective solutions. Various compounds produced during pretreatment may interfere with BC production. Low concentrations of aliphatic acids enhance BC production, while high concentrations suppress it. Miscanthus, barley straw, and pine tree hydrolysates show potential for efficient BC production under optimal conditions.

Summary: The objective of this research is to explore the potential utilization of Palmyra palm jaggery in the production of bacterial cellulose by Gluconacetobacter liquefaciens. The study found that under shaking conditions, Palmyra palm jaggery in the PHS medium resulted in the highest concentration of bacterial cellulose compared to other carbon sources in the HS medium. The use of PHS medium without nitrogen source could be a cost-effective nutrient for bacterial cellulose production.

Summary: This study developed a material with antioxidant and moisturizing characteristics for possible cosmetic applications by adding grape skin residue extract to a polymeric matrix based on bacterial cellulose through in situ and ex situ methods. The samples showed antioxidant activity, with the highest value found in the sample produced with fermentation medium containing pure grape skin residue extract. The high water retention capacities, high porosity, and low crystallinity of the samples favor the development of cosmetic products with enhanced moisturizing effect and active compound incorporation ability.

Summary: In Gluconacetobacter xylinus cultivation, agro-industrial wastes, such as soybean residual okara, okara extracted protein, and modified okara protein, were used as a protein source to enhance bacterial nanocellulose production. Acetic-acid modified protein showed improved solubility and smaller particle size, resulting in higher cellulose yield. The utilization of okara waste provided enhanced economic feasibility and sustainability in nanocellulose production.
