Interests in the development and exploration of industrial applications of medicinal mushrooms as postbiotics have lately increased. We recently reported the potential use of Phellinus linteus mycelial-containing whole culture extract (PLME) prepared by submerged cultivation as a postbiotic that promotes immune system activation. Here, we aimed to isolate and structurally elucidate the active ingredients in PLME by activity-guided fractionation. The intestinal immunostimulatory activity was evaluated by bone marrow (BM) cell proliferation activity and related cytokine production in C3H-HeN mouse-derived Peyer's patch (PP) cells treated with polysaccharide fractions. The initially crude polysaccharide (PLME-CP) of PLME prepared using ethanol precipitation was further fractionated into four fractions (PLME-CP-0 to -III) by anion-exchange column chromatography. BM cell proliferation and cytokine production of PLME-CP-III were significantly improved compared to those of PLME-CP. PLME-CP-III was then fractionated into PLME-CP-III-1 and PLME-CP-III-2 by gel filtration chromatography. Based on the molecular weight distribution, monosaccharide, and glycosyl linkage analyses, PLME-CP-III-1 was revealed as a novel galacturonic acid-rich acidic polysaccharide and further shown to play an important role in facilitating PP-mediated intestinal immunostimulatory activity. This is the first study demonstrating the structural characteristics of a novel intestinal immune system modulating acidic polysaccharide from P. linteus mycelium-containing whole culture broth postbiotics.
