Abstract

A new generation elastomeric biopolymer produced by yeast belonging to the family Saccharomycetaceae, and an isolated yeast belonging to the genus Williopsis that produces and secretes the biopolymer.

Claims (12)

1. An elastomeric biopolymer made in accordance with the following steps:

inoculating growth medium with an isolated yeast belonging to the genus Williopsis;

providing nutrients to the growth medium;

growing the yeast;

producing the biopolymer;

isolating the polymer; and

purifying the polymer.

2. The elastomeric biopolymer according to claim 1 wherein the growing step is carried out aerobically.

3. The elastomeric biopolymer according to claim 1 wherein the growing is carried out between approximately 20° C. and approximately 40° C.

4. The elastomeric biopolymer according to claim 1 wherein the growing is carried out at a pH between approximately 2 and approximately 9.

5. The elastomeric biopolymer according to claim 1 wherein the isolating is carried out by harvesting the medium while preserving the yeast for further production.

6. The elastomeric biopolymer according to claim 1 wherein the isolating is carried out by centrifugation.
