Abstract

SUMMARY: Forty-two bacteria-free cultures of pennate diatoms from fresh water or soil were tested for ability to grow heterotrophically with glucose as the sole carbon source. Thirteen of these isolates proved capable of growth under these conditions. They comprised seven isolates of , five of other different species of , and one of (?)

One isolate of was tested for its ability to grow heterotrophically on any one of sixty organic compounds. Only glucose, glycerol, and fructose were found to be effective in supporting growth. Glucose was metabolized both in the dark, and in the light in the absence of CO. Glycerol and fructose were not utilized in the dark, but supported growth in the light in the absence of CO.
