Pharmaceutical Sciences and Research
The field of study on extracellular vesicles (EVs) has recently focused on probiotic bacteria, due to their ability to exhibit a wide variety of biological activity. Therefore, this study aims to evaluate the effect of nutrient modulation during Lacticaseibacillus paracasei cultivation on EVs production and bioactivity. EVs were isolated by ultrafiltration method and were characterized using NTA and cryo-TEM. An in vitro evaluation was used to assess the bioactivities, antioxidant properties, anti-inflammatory potential, and ability to inhibit α-glucosidase activity. The results showed that the 2 LPEV exhibited the characteristics of vesicles with size of 96.04–100.29 nm. Cultivation in 50% MRS …
