SUMMARY A comparative examination of the growth of 15 species of Hansenula in typical ‘fat’ media has been undertaken. Seven species showed a good yield on the basis of sugar consumed and, in terms of fat content, they fell into three broad categories. H. ciferrii and H. saturnus had a fat content ( c. 20%) rather lower than that of Rhodotorula gracilis grown under the same conditions; 2 strains of H. anomala had a fat content of about 13%, and H. jadinii, H. angusta and H. subpelliculosa had a relatively low fat content ( c. 8%). In a ‘fat’ medium containing urea as principal nitrogen source there was an initial phase during which most of the nitrogen was assimilated, followed by a phase during which most of the fat accretion occurred.
