1. A recombinant yeast strain comprising a strain of S. cerevisiae and an exogenous MAL1 gene cluster comprising a MAL11 gene, a MAL12 gene, and/or a MAL13 gene, wherein the strain of S. cerevisiae expresses the exogenous MAL1 gene cluster, wherein the exogenous MAL1 gene cluster comprises a sequence having at least 80, 85, 90, 95, or 98 percent homology to SEQ ID NO: 2; and wherein the recombinant yeast strain further comprises an exogenous MAL2-8c gene cluster, wherein the exogenous MAL2-8c gene cluster comprises a sequence having at least 80, 85, 90, 95, or 98 percent homology SEQ ID NO: 3.
