Summary: An efficient method for recovering rebaudioside A from mother liquor sugar was developed by using inorganic salts to increase its concentration and mass ratio. This method showed advantages of high recovery yield, short recovery time, simple operation, and lack of organic solvents, providing a potential alternative for treating similar mother liquors.

Summary: This study focuses on designing integrated facilities for the production of xylitol and sorbitol from lignocellulosic biomass. Various pretreatments, hydrolysis, fermentation, and catalytic hydrogenation are considered to process different biomass feedstocks into the desired products. An economically optimized system with 3 crystallizers is selected to improve production efficiency and reduce costs for xylitol and sorbitol.

Summary: This study evaluates the economic feasibility of a biorefinery producing sugar from lignocellulosic biomass using a combination of autohydrolysis and mechanical refining pretreatment. The biorefinery is self-sufficient in energy and able to produce excess electricity for sale. The analysis also explores the potential for using by-products, such as dissolved hemicellulose and lignin, to produce high-value products like xylitol and polyol.

Summary: This work develops a rapid methodology for evaluating the critical caking cycle of xylitol, which saves 85% of the time and 90% of the labor compared to conventional assessment methods while ensuring precision accuracy. By establishing a Caking-Hygroscopicity-Particle size crystal bridge growth model, the correlation and quantitative relationships among hygroscopic properties, particle size, and the critical caking cycle are established for the first time, simplifying time-consuming water sorption measurements and caking tests. The obtained knowledge can guide the selection of storage humidity conditions and appropriate particle size distributions for maintaining the desired properties and competitive marketability of crystalline sugar alcohols.

Summary: Gut microbiota can produce aromatic amines, which are different from dietary sources. The production of these aromatic amines is related to the activity of aadc in gut bacteria and may have an impact on diseases such as osteoporosis and irritable bowel syndrome. Human AADC inhibitors can inhibit the production of aromatic amines in gut bacteria.

Summary: Understanding the dynamic environmental microniches of biofilms will help us detect, manage, and exploit these communities, although there is still limited knowledge about the existing microniches. The use of ratiometric fluorescent pH-sensitive nanosensors allows real-time observation of physiological pH changes in biofilms, offering a potential application for identifying therapeutic solutions. This technology can be applied to analyze real-time three-dimensional pH variations in different biofilm formers like opportunistic pathogens and oral pathogens, providing insights into improving oral health.

Summary: This study investigated thermophilic chain elongation from grass juice and found that the optimal condition for caproic acid production was pH 6.0 and 50°C. Glucose and xylose served as the substrates for producing high concentrations of caproic acid, while lactic acid only led to the production of butyric acid. Continuous operation with increased total sugar concentration through glucose addition further enhanced caproic acid production.
