Heterotrophic Bacterial Populations of the Black Sea

The total bacterial populations inhabiting Black Sea waters and sediments off Romania were examined quantitatively, and the aerobic, heterotrophic populations were examined both quantitatively and qualitatively. Results showed a large bacterial population in anoxic waters ( = 8.8 × 105 cells/ml) and sediments ( = 4.9 × 10” cells/g), as well as in the aerobic environments. A very small portion of the total population could be grown on a...
