Notes
The wet and dry weights of both axenic and monoxenic cultures of the ciliate Tetrahymena were determined directly. These estimates are dependent upon the method of volume determination. Assuming a prolate spheroidal shape for the ciliate, we calculate a mean wet weight of 0.4157+/-0.0713 pg um-3 and a mean dry weight of 0.2793+/-0.0652 pg um-3. Using electronic cell sizing, our estimates are 0.7869+/-0.1659 pg um-3 and 0.5239+/-0.1101 pg um-3, respectively. Independent of the method of volume determination, we estimate a mean biomass conversion ratio (dry weight/wet weight) of 0.59+/-0.08.
