Pleurotus eryngii, also known as the king oyster mushroom or cardoncello, is gaining considerable popularity amongst consumers worldwide (Rodriguez Estrada and Royse 2007). It is a good source of dietary fiber, including β-glucans, and consists of various antioxidative compounds such as polyphenols, polysaccharides, lipids, peptides, and sterols (Fu et al., 2002; Ngai and Ng 2006; Ferreira et al., 2009). Recently, Pleurotus species have been reported to be of potential therapeutic value, based on their antioxidant, antitumor, and immunomodulatory activities (Caglarlrmak, 2007; Mori et al., 2008; Ferreira et al., 2010).
