A low-molecular-weight α-glucan PPS2-A derived from potato starch fermentation by Antarctic Penicillium chrysogenum MS-02: Structural characterization and immunomodulatory activity.
Glucan, a potent immunomodulator with well-established pharmacological activities, can be efficiently produced through the microbial transformation of low-value substrates. Here, the psychrotolerant Antarctic fungus Penicillium chrysogenum MS-02 was cultivated on potato starch. A homogeneous glucan with molecular weigh...
