Effects of alginate and laminaran on microbiome and antioxidant properties of human faecal cultures

Fermentation in human faecal culture with alginate and laminaran differed among individuals. B. xylanisolvens and E. ramosum were identified as polysaccharide-responsive bacteria (RIB). Butyrate producers F. prausnitzii and Roseburia sp. were also suggested as alginate and laminaran RIB. Antioxidant capacities in the cultures were increased via fermentation.
