HYDROCHEMICAL DATA FOR MASS OCCURRENCE OF HAEMATOCOCCUS-PLUVIALIS (CHLOROPHYCEAE)

Haematococcus pluvialis FLOTOW emend. WILLE is a widely distributed al ga inhabiting small astatic waters. The species appeared in large amou nts spontaneously in a laboratory aquarium and in an Erlenmeyer-flask filled with drinking water. The glassplates of the aquarium and the su rface of the water were covered with a thick layer of immobile, spheri cal, red cells (aplanospores). This paper presents hydrochemical data as well as results of cultivation experiments performed in different m edia (chemical solutions, filtered waste water and freshwater).
