The Chryophyceae were maximally represented by Synura

Studies on the genera Mallomonas, Synura
, and other plankton in freshwater by the electron microscope.
Twenty-seven silica-scaled synurophycean and chrysophycean taxa from five genera, Mallomonas (14 taxa), Synura (10 taxa), Spiniferomonas (two taxa), Paraphysomonas and Chrysosphaerella (one taxon each) were observed from the 35 samples.
Common species from other genera were Synura uvella (34%), S.
With respect to taste and odor control, there are a number of studies reporting on the successful use of chlorine dioxide in the treatment of musty odors, fishy tastes and odors from Mallonmonas, and taste and odor problems associated with Anabaena, Asterionella, Synura
, and Vorticella, as well as actinomycetes which are a source of geosmin and 2-methylisoborneol (MIB).

Although there are clear qualitative indications of greater pH values, especially in the profiles of Mallomonas caudata and Synura
spinosa, the two pH-circumneutral species in these assemblages, only one change of CIpH exceeds the RMSE of the transfer equation (= 0.
