| 1. A process for production of polyunsaturated fatty acids comprising the following steps:
a) incubating monounsaturated acetylenic fatty acids or monounsaturated olefinic fatty acids with a double bond of E type
with strains of Saccharomyces cerevisiae yeast in liquid medium; and
b) extracting and purifiying the polyunsaturated fatty acids of the culture medium, product of the incubation of a).
