was observed in potassium dihydrogen phosphate deficient BBM
(Figure 5) . In Figure 6, autospores of T.. bitridens are
shown being liberated from the parent cell. An enlarged
aberrant cell of T. bitridens is shown in Figure 7 as it
appeared in potassium monohydrogen phosphate deficient BBM.
Bristle formation in A. falcatus can be seen in Figure 8 and
Figure 9. In Figure 9, autospores have been formed by trans-
verse division of the parent cell. During the eighth week of
culture in complete BBM, cells of Ankistrodesmus sp. were
filled with grey oil droplets similar to those observed in
ammonium nitrate deficient BBM (Figure 10). Aberrant cells
of Ankistrodesmus sp. are shown in Figure 11 and Figure 12 as
they appeared in magnesium sulfate deficient BBM. In BBM
lacking microelements, autospores were formed in pairs as
shown in Figure 13. Note also that plastids in the daughter
cells are not parietal and only partially fill the cells.
During the course of this investigation, the pH varied
no more than 0.3 of a pH unit from the initial of any of the
respective media.
