Hello Mr. Basil Dmello,

The specimen in your microscope field image certainly looks like to be a centric diatom or it could also be a member of the family Chrysophyceae but it requires a higher magnification to shed light on the right direction. However, the species growing on the plate is perhaps a benthic species of microalgae.

Dr. Abhishek Mukherjee

some colourless cells looks like Cosmarium sps. (may be)

Hi Basil,

The attached image is not informative enough. Please if possible provide some better images with higher magnification. But these suggestions might be true: Cosmarium and Chlorella (please see the attached image).

Regards,

Reza

Hi Basil;

Magnification is not enough to see detail of microalgae. May be make permenant slide for diatom and examine 1000x.

Good luck

I think there are diatoms. However, in cultures it is difficult to determine diatom species. Usually the shapes change during the culturing period. The final individuals are not identical with the orginals. Therefore a species determination is not possible any more.

Besides there are Chlorella like green algal cells.

The major component should be some diatom species as suggested by Dr. Schanz. Sharp photomicrographs

at higher magnification and /or SEM may be required for species identification. Few green microalgae can also be observed.
