Prebiotic activity of paramylon isolated from heterotrophically grown Euglena gracilis

Paramylon from Euglena gracilis is an insoluble crystalline beta-1,3-glucan which have pharmaceutical and nutraceuticals applications. The present study aims to check the prebiotic potential of paramylon derived from heterotrophically grown E. gracilis in bioreactor. The Paramylon was extracted using sodium dodecyl sulfate from E. gracilis biomass. The Fourier Transform-Infra Red spectroscopy and scanning electron microscopy demonstrated the isolated paramylon to be equivalent to that of analytical standard. The prebiotic activity of E. gracilis cell extract and isolated paramylon was studied. E. gracilis cell extract as well as isolated paramylon led to cell number enhancement of Lacfid (Lactobacillus) strain exhibiting the prebiotic activities.

Automated summary

The study extracted paramylon from Euglena gracilis and examined its prebiotic potential on probiotics, confirming its ability to enhance the growth of Lactobacillus strain, showing prebiotic activities.
