The effect of abate on the growth of Vibrio natriegens and Chlorella vulgaris

The effect of Abate on the growth of a species of bacteria, Vibrio natriegens, and a species of algae, Chlorella vulgaris, was studied. The growth of V. natriegens was measured by both the changes in the optical density and the viable counts of the bacterial suspension. Changes in the optical density of the alga measured by a colorimeter and by the direct counting the number of cells with a haemocytometer were taken as an index of growth. Abate was found to be not significantly toxic to both organisms at concentrations below 5 ppm.
