Oligogalacturonic acids from citrus pectin: structural characterization and mechanistic insights into hydrophobic-antibacterial effect.

A highly alkaline pectate lyase from Marinimicrobium sp. EAC58 and improved thermostability by rational design.

BACKGROUND Pectic oligosaccharides (POS) are novel prebiotics derived from pectin, exhibiting diverse bioactivities including antimicrobial, antitumor, antioxidant and immunomodulatory activity. As promising functional food ingredients, POS have attracted considerable attention for their health benefits. Enzymatic prod...

Microbial valorization of pomegranate peel pectin into pectic oligosaccharides with selective anticancer activities: in vitro and in silico evaluation

Sustainable valorization of lemon juice pomace into bioactive pectin: Experimental cytoprotection, molecular docking, and DFT analysis against cadmium-induced oxidative damage.

This study uniquely integrates extraction optimization, structural characterization, cytoprotection, molecular docking, and DFT analysis to valorize lemon juice pomace pectin within a circular bioeconomy framework, distinguishing it from previous work limited to peel pectin or crude extracts. The extraction process was...

Preparation, Structural Elucidation, and In Silico Prebiotic Evaluation of Pectin Oligosaccharides from Apple Pectin

Pectin oligosaccharides (POS) recovered from agro-industrial by-products are attracting attention as candidate prebiotics, yet obtaining structurally defined neutral POS and screening their activity remains challenging. This study prepared neutral POS from commercial apple pectin by controlled acid hydrolysis (0.05 M T...

Comparative Characterization of Polysaccharides from Rosa roxburghii Tratt. Fruits Collected from Eight Major Producing Areas of Guizhou: Structure, Physicochemical Properties, and In Vitro Bioactivity

Polysaccharides from Rosa roxburghii Tratt. (RRTP) are predominantly pectic and are considered core bioactive compounds of the fruit. In this study, RRTPs were extracted from fruit of the cultivar ‘Guinong 5’ collected from eight major production areas in Guizhou, China, to evaluate source-associated differences in pec...

Effects of nonionic surfactants on the production of extracellular polysaccharides, citrinin synthesis, physicochemical structural characteristics, and in vitro hypoglycaemic activity of Monascus purpureus YY-1.

Monascus extracellular polysaccharides exhibit diverse bioactivities, including antioxidant, antitumor, and immunomodulatory effects. Nevertheless, their low native yield restricts practical applications. To improve the fermentation yield and functional properties of EPS, Monascus purpureus YY-1 was employed as the exp...
