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: Cacao mucilage exudate (CME) can be used to produce bacterial cellulose (BC), but high sugar content, low pH, and limited nitrogen sources in CME can hinder G. xylinus growth affecting cellulose yields. By diluting CME and adding a nitrogen source, BC production significantly increased. Scaling up BC production from 30 mL to 15 L under lab-scale conditions showed no significant changes in yields and production rates, suggesting industrial possibilities are feasible.

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: This study focused on the potential effects of effluent composition, particularly hydrocarbons, on aquatic toxicity in oil refineries. The research found that measured bioavailable hydrocarbons using BESPME correlated with responses in standard bioassays, confirming the relevance of bioassays and the importance of BE-SPME measurement in toxicity identification. Overall, the study suggests that oil refinery effluents treated in accordance with EU regulations have low to negligible toxicity to aquatic organisms.

Summary: This study investigated the use of date syrup for producing bacterial cellulose (BC) by Gluconacetobacter xylinus. BC was produced in Hesterin-Schramm (HS) medium and achieved the highest yield after 12 days of cultivation at pH 8. Modified HS media containing date syrup were then used, resulting in a 75% higher production yield compared to HS medium. The BC produced in the modified media had long fibrils with diameters less than 70 nm, and the crystallinity index was higher in the specimen produced in MHS1 medium containing peptone compared to that in MHS2.

Summary: Taiwan's livestock industry has contributed significantly to agricultural development, but it generates wastewaters that cause water body eutrophication. Bioremediation of high-strength wastewaters using immobilized microalgae has been found to be effective. The study showed that culturing Chlorella sorokiniana AK-1 with Gluconacetobacter xylinus in molasses-based bacterial cellulose resulted in highly porous cellulose, facilitating microalgal attachment and growth. The microalgae immobilized on bacterial cellulose exhibited high removal efficiency for carbon, nitrogen, and phosphorus in dairy manure wastewater.

Summary: Fabrication of bead-free nanofibers from pure casein is challenging due to its self-aggregation tendency. In this study, the influence of pH, ethanol content, ionic environment, and casein concentration on the solubility and solution characteristics of casein-based spinning dopes was analyzed. The addition of tetrasodium pyrophosphate (TSPP) reduced bead defects and improved the properties of the nanofibers. The viscosity of the solution depended on the casein concentration, and bead-free nanofibers were obtained at a concentration higher than the entanglement concentration (C-e).

Summary: This study investigated the synergetic gelation of curdlan gum (CG) and gellan gum (GG) at different ratios. The optimal gelation was achieved at a mass ratio of 1:1 and a total concentration of 0.6%. The gel properties were influenced by the CG/GG ratio, with the strongest gel observed at a ratio of 5:5. The improved gel properties were attributed to hydrogen bonds between CG and GG. The CG/GG binary composite gel exhibited increased water holding capacity as the CG/GG ratio decreased. Furthermore, the microstructure of the CG/GG gel was denser and more homogeneous, supporting its stronger gel rigidity and water holding capacity.

Summary: This study investigated the influence of highly-branched cyclic dextrin (HBCD) on the physiochemical properties of x-carrageenan (KC) gels. The addition of HBCD significantly enhanced the storage modulus and freeze-thaw stability of KC gels. HBCD promoted the distribution of KC chains and aggregation of KC helixes, resulting in a compact network structure and reduced water loss. Furthermore, HBCD strengthened the thermal reversibility of KC gels through enhanced hydrogen-bonding interactions.
