CLONING AND CHARACTERIZATION OF L-ARABINOSE TRANSPORTERS FROM NON-CONVENTIONAL YEAST

摘要

Two genes from non-conventional yeast encode arabinose transporters. These arabinose transporters are capable of transporting arabinose across the cell membrane. These genes may be expressed heterologously in a host that is not otherwise capable of taking up significant amounts of arabinose from the environment of use. Methods are disclosed to use such genetically engineered hosts to ferment pentose such as arabinose, to produce ethanol.
