Abstract

The goal of this study was to synthesize relatively stable essential fatty acid of n-3

and n-6 series by chemical and biological method.

The first attempt was to elongate alpha-linolenic acid to eicosatrienoic acid or fatty

acids of longer chain length with Rhodotorula glutinis and yeast strain 572. The yeast grew

rapidly at 30°C. in medium with or without linseed soap which contained alpha-linolenic

acid about 60% of total fatty acid. Analysis of fatty acids from yeasts by gas

chromatography showed that the yeast could assimilate alpha-linolenic acid into the cell but

did not elongate. Assimilation of fatty acid as well as growth of yeast decreased as

temperature decreasing. It was concluded that the yeasts, R. gUnis and yeast strain 572,

could not convert linseed oil alpha-linolenic acid to any fatty acid of longer chain length.

Attempt biohydrogenate fish oil anaerobically with Sacc~omyces cerevisiae was

mlsuccessful. Lipid isolated from yeast treated with fish oil did not contain any

hydrogenated fatty acid of eicosapentaenoic acid or docosahexaenoic acid, suggesting that

the yeast was not able to biohydrogenate at this condition.

Hydrazine reduction of alpha-linolenic acid of linseed oil was very promising.

Analysis of reduction products by gas chromatography and mass spectrometry indicated that

the product contained one double bond at the n-6 (o&a&c-12-enoic acid) and n-3 (octadec-

1%enoic acid) position. The optimum molar ratio of fatty acid to hydrazine was 1 to 8 in

ethanol and amount of potassium ferricyanide was 0.2 gram per 5 millilitre. When water

was used as hydrogenation solvent, yields of octa&c-12-enoic acid and octadec-15-enoic

acid were increased from 14.1% and 6.4% to 15.4% and 8.7% respectively, but there was

no selectivity on the double bond position. At pH 9.9, rate of reaction was faster and easily

controlled. Reaction rates were highest at temperature 70 to 90°C but the maximum yields

were equal to that obtained at 30°C .
