Article Synopsis
  • - The study investigates how the anthocyanin extract from Lycium ruthenicum (LRA) can help delay aging in Agaricus bitoquis fungus cells while boosting the production of beneficial polysaccharides (PS) known for their anti-hypoxia and antioxidant properties.
  • - Through advanced analysis techniques like UHPLC-Q-TOFMS and RNA sequencing, researchers found that LRA alters metabolic pathways, encouraging the synthesis of polysaccharides and antioxidants, which enhances cell function and reduces toxicity.
  • - The optimized fermentation process demonstrated that adding LRA significantly increased mycelial biomass and production of extracellular and intracellular polysaccharides, with strong predictive models showing over 0.95 correlation coefficients, indicating accurate simulation of fermentation

Angiotensin-I converting enzyme (ACE) inhibitory peptides drew wide attention in the food industry because of their natural reliability, non-toxicity, and safety. However, the characteristics of ACE inhibitory peptides obtained from protein hydrolysate of mulberry leaf prepared by Flavourzyme were still unclear. Based on the single-factor test, the Plackett-Burman test and response surface test were used to determine the key factors affecting the ACE inhibition rate in mulberry leaf protein hydrolysate and the optimum conditions of enzymatic hydrolysis.

Two polysaccharides, ALF1 and ALF2 were obtained from the fermentation liquid of Floccularia luteovirens. These fractions had good performance in scavenging radicals and ALF1 exhibited obvious antioxidant activities. Further, linkage analysis and NMR were used to characterize the structures of ALF1.

Several chitosan sodium tripolyphosphate (TPP) nanoparticles embedded with Torreya grandis aril essential oils (TEOs) were synthesized using an emulsion-ionic gelation technique. Mannosylerythritol lipid A (MEL-A), a type of biosurfactant, was selected as the emulsifier. In order to replace acetic acid, an ionic liquid (IL) was employed to dissolve chitosan.

Article Synopsis
  • Increasing interest in microbial exopolysaccharides (EPSs) has led to the study of halophilic microorganisms, particularly a moderate halobacterium identified as ZJUQH CCTCC M2016754, which thrives in 10% NaCl environments.
  • The research focused on optimizing EPS production by experimenting with different fermentation medium compositions, revealing that KCl and MgSO₄ significantly influence EPS yield.
  • The ideal culture medium was determined, producing a maximum EPS concentration of 70.64 g/L in a bioreactor, indicating ZJUQH's potential applications in food, pharmaceuticals, agriculture, and environmental biotreatment.
