Abstract
Scenedesmus culture 16, a pleomorphic soil alga, produced colonies resembling S. quadricauda, S. longus, S. abundans, S. bijugatus, and S. acutiformis when grown in stationary flasks in three standard laboratory media. The unicell population was always low under such conditions.When transferred daily in several media containing ammonium ions and buffered at pH 8.5 or above, a unicell population was formed; no coenobia were present. The unicells had delicate spines randomly placed over the cell surface and resembled the genus Franceia. Co-action of other ions in the medium with the ammonium could not be demonstrated. Stored media with Tris buffer showed a steady decline in pH.This publication has 8 references indexed in Scilit:
