Article Synopsis
- Green tea residues, a by-product of tea processing, are rich in bioactive compounds, and steam explosion is an innovative method to alter the characteristics of polysaccharides from these materials.
- This study compared the effects of polysaccharides from steam exploded green tea residues (SE-GTR) and unexploded green tea residues (UN-GTR) on gut microbiota and found that SE-GTR had a higher polysaccharide content and improved gut health benefits after fermentation.
- The steam explosion treatment resulted in increased production of beneficial metabolites such as acetic, propionic, and butyric acids, while also promoting the growth of beneficial bacteria like Bifidobacterium, suggesting it enhances the nutritional value of tea residues.

Article Synopsis
- A series of activated biochars were produced from bamboo powder using KOH and pyrolysis at different temperatures, with physicochemical properties analyzed through various techniques like SEM and XRD.
- The biochar sample KBBC-900, activated at 900°C, showed superior adsorption performance for removing methylene blue (MB), achieving a capacity of 67.46 mg/g under optimal conditions.
- Adsorption kinetics indicated a rapid equilibrium at around 20 minutes, primarily driven by chemical adsorption, with the process being spontaneous and endothermic, suggesting that this activated biochar is promising for treating wastewater containing MB.
Coix seed polysaccharides had received increasing attention due to their diverse biological activities. In this study, a homogeneous polysaccharide (CSPW) was extracted and purified from coix seed. Furthermore, the saliva-gastrointestinal digestion and fecal fermentation behavior of CSPW were simulated in vitro.

To investigate IDF- induced changes in the production of short-chain fatty acids (SCFAs) and the composition of human gut microbiota, IDF was extracted by alkaline hydrogen peroxide (named BIDF), complex enzymatic hydrolysis method (named OIDF) from bamboo, and commercial bamboo fiber BF90. The in vitro fecal fermentation characteristics of BIDF, OIDF, BF90 and its impacts on human gut microbiota were studied for the first time.

Methods: Electronic searches were performed to identify all publications describing randomized controlled trials (RCTs) on the use of GH with or without glutamine for the treatment of patients with SBS. The outcomes of interest were body weight, lean body mass, and intestinal absorption function.
