✦ Synopsis

A Micrococcus cerificans strain was grown on simple media with n-hexadecane or gas oil as sole carbon sources. Samples of cellular material recovered from hexadecane or gas oil fermentations do not appear to differ significantly in their composition.

With the exception of sulfur amino acids the amino acid distribution compares favorably with the FA0 standard reference protein.

The biological value of cell protein recovered from hexadecane fermentations was 67 (casein, 70). In the caae of gas oil grown cells, the cell material recovered had to be completely purified in order to improve its protein quality. After fully extraction of undesirable fraction with petroleum ether in a Soxhlet apparatus the biological value observed was 63.
