WebDiatom cultures were purchased from Loras College (Dubuque, Iowa); they were A. minutissimum (strain identification LI468), C. p. lineata (023), and Cymbella cistula (LI550). Taxa in the mixed treatments were selected because of their morphological and growth traits. A. minutissimum and C. p. lineata were assumed to have similar modes of
WebThe diatom yields in mixed cultures ranged from 0.8 to 84% of the yields in axenic cultures with added B 12. In a detailed study of one mixed culture, increases in diatom densities were paralleled by increases in cell densities of the bacterium during the first few days of exponential diatom growth.
