LITERATURE SUPPORTvia PubMed search ('NaOH') PMID:37817899
Key features • Production and extraction of EPS from submerged cultures of mycelial forms of macrofungi. • Modification of the method described by Fariña et al. (2001), extending its application to submerged cultures of mycelial forms of the macrofungi. • Determination of EPS production parameters in submerged cultures of mycelial forms of macrofungi. • EPS solubilization using NaOH (0.1 N).
