“…Aureobasidium pullulans is a dimorphic fungus, which is commonly distributed throughout the environment, especially in soil and plants (Krogh et al 1998;Yoshikawa et al 2006). This fungus is able to grow well in the presence of high concentrations of saccharides, and produces polysaccharides (pullulans and β-glucan), oligosaccharides (FOS and isomaltooligosaccharides) and various carbohydrate-degrading enzymes (Deshpande et al 1992;Yun et al 1994;Hamada et al 2000). A. pullulans may be a potential candidate for bioremediation of heavy metal contaminated environments, as this fungus has been shown to assimilate certain heavy metals, such as zinc, cobalt, cadmium and copper (Gadd et al 1987;Krogh et al 1998).…”
