Cloning of the Schwanniomyces occidentalis α-amylase and high expression in S.cerevisiae.The E.coli / yeast shuttle plasmid YCEpl partial library of Schwanniomyces occidentalis DNA was constructed and α-amylase gene fragments were screened in Saccharomyces cerevisiae by amylolytic activity.Several transformants with amylolysis were obtained and one of the fusion plasmids has about 5.0 kb inserted DNA fragment.It contains the upstream and downstream sequences of α-amylase gene from S.occidentalis .
