Glucose and sodium acetate are the only carbon sources able to support heterotrophic growth of Golenkinia minutissima Iyengar & Balakrishnan. Heterotrophic growth is maximal at a concentration range of 20–40 mM of either carbon source; however, growth is significantly more rapid and higher yields are obtained with acetate. Mannose is toxic but this effect is competitively reduced by the presence of glucose. The inhibitory action of acetate on chlorophyll synthesis is unaffected by 20 mM glucose, indicating that this inhibition is not related to the absence of glucose.
