ACETATE METABOLISM BY WHOLE CELLS OF <em>PHAEODACTYLUM TRICORNUTUM</em> BOHLIN.

Both morphological forms of Phaeodactylum tricornutum incorporated acetate in the light and in darkness. In the dark, the majority of the acetate was oxidized, probably by the tricarboxylic acid cycle. Although some CO[SUB2] was formed from acetate in the light, most acetate carbon was found in the cellular lipids. Acetate incorporation in the light was probably a result of both direct and indirect assimilation. The organism grew poorly an acetate in the light at a very low CO[SUB2] tension.
