Research ArticleOpen accessIn the author namesFabrication of Polysaccharides from a Fermented Tea and Their Antioxidant and Hypoglycemic ViabilityJun Li, Lingxian Tong, Bing Li et al.The hypoglycemic effects of tea have been extensively studied, with fermented tea demonstrating notable efficacy owing to its distinct processing methods. This study involved the extraction of tea polysaccharides from Wuniuzao Black Tea (WTP) using a water extraction and ethanol precipitation method. WTP-1 and WTP-2 were obtained by separation and purification using DEAE-52 cellulose columns. Antioxidant activity was evaluated utilizing … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 30 Jul 2026 · 655 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEffect of Metformin Treatment on Inflammatory Factors and Gut Microbial Diversity in Patients with Type II Diabetes MellitusLei Tong, Jingjing Zhang, Li Xiao Yue et al.With the persistent rise in the prevalence of Type 2 Diabetes Mellitus (T2DM), traditional treatment evaluations have primarily focused on glycemic control, often overlooking the multidimensional effects of medications. As a first-line therapeutic agent, the anti-inflammatory effects and gut microbiota regulation mechanisms of metformin remain incompletely elucidated. This prospective cohort study established a metformin treatment group and a T2DM control … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 20 Jul 2026 · 774 accessesView PDF Cite

Research ArticleOpen accessIn the author namesScreening of Dominant Cellulose-Degrading Microbe in Humus and Optimisation of its Enzyme Producing Conditions and Application Optimization of Enzyme Production Conditions and Evaluation of Efficient Straw Degradation by Penicillium oxalicumGailing Wang, Chendi Li, Yanan Guo et al.The slow degradation of returned straw adversely affects seedling survival rate. To shorten the degradation time of lignin in maize straw in warm temperate regions, a cellulolytic microbial strain that can secrete polymer with high enzymatic activity was isolated from the humus, which helped to identify an effective strain to expedite the decomposition of returned maize straw. Using the molecular … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 23 May 2023 · 5,300 accessesView PDF Cite
