Biomolecules, Journal Year: 2024, Volume and Issue: 14(9), P. 1162 - 1162

Published: Sept. 16, 2024

Microbial exopolysaccharides (EPSs) are receiving growing interest today, owing to their diversity in chemical structure and source, multiple functions, immense potential applications many food non-food industries. Their health-promoting benefits for humans deserve particular attention because of various biological activities physiological functions. The aim this paper is provide a comprehensive review microbial EPSs, covering (1) biochemical diversity, including composition, biosynthesis, bacterial sources belonging mainly lactic acid bacteria (LAB) or probiotics; (2) technological analytical aspects, especially production mode characterization; (3) aspects based on functions; (4) current future uses medical pharmaceutical fields, particularly prebiotic, anticancer, immunobiotic properties, as well other industrial agricultural sectors.

Structural characterization and antioxidant activity of a polysaccharide produced by Chaetomium globosum CGMCC 6882 from waste tobacco leaves

Preparative Biochemistry & Biotechnology, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 10

Published: Feb. 18, 2025

Due to the restricts of treatment methods and high costs, waste tobacco materials are usually discarded, which leads resources environmental pollution. Present work used leaves as carbon source produce polysaccharide (CGP-TL) by Chaetomium globosum CGMCC 6882 via submerged fermentation. CGP-TL yield was 1.62 ± 0.35 g/L, contents carbohydrate protein in were 91.73% 6.49% 5.51% 0.84%. Structural characterization showed composed rhamnose, arabinose, galactose, glucose, mannose xylose a molar ratio 9.9688: 6.8482: 19.6045: 29.4448: 0.8033: 0.5874. Meanwhile, its weight-average molecular weight, number-average weight polydispersity 286.035 kDa, 118.146 kDa 2.421, respectively. In vitro antioxidant analysis scavenged DPPH, ABTS, hydroxyl superoxide radicals positively correlated concentration, corresponding scavenging effects at 2.5 mg/mL 75.53% 1.89%, 96.24% 2.32%, 52.91% 2.28% 65.26% 2.47%. Furthermore, not only improved antioxidative status RAW 264.7 cells, but also exerted oxidative repairing on H2O2-damaged cells increasing levels SOD, CAT GSH-Px, reducing MDA level. Overall, this will provide references for green efficient utilization cellulose resources.

Published: Feb. 24, 2025

This paper reviewed the diversity of endophytic fungi and their interactions with medicinal plants, along research methodologies utilized to investigate these interactions. It mainly includes fungi, as well distribution diversity, species metabolites functions, including antibacterial, anti-inflammatory, anti-tumor, insecticidal, antioxidant capabilities, so on. The employed between plants are categorized into metagenomics, transcriptomics, metatranscriptomics, proteomics, metabolomics. Furthermore, this study anticipates potential applications secondary derived from in both medicine agriculture.
