Epipsammic diatoms of diatoms of Kelkit Creek (Tokat/Turkey)

In this study, diatoms in epipsammic samples, which were taken from two stations selected in Kelkit Creek (Tokat/Turkey) between March and December 2018, were analyzed. During the study, a total of 25 taxa belonging to diatoms were recorded. The diatom species represented by the highest number of taxa were Cymbela (4 taxa), Nitzschia (4 taxa), and Navicula (3 taxa). Sorensen similarity index be...

Silicon Metabolism in Diatoms

1. Cells of the fresh water diatom Navicula pelliculosa may be grown in a mineral medium containing a low concentration of silicon. When transferred to a fresh silicate solution and incubated under non-growing conditions such deficient cells rapidly take up silicon from the medium. 2. The utilization of silicon is an aerobic process. 3. When deficient cells are washed with distilled water or sa...

Photosynthetic Pigments in Diatoms

Photosynthetic pigments are bioactive compounds of great importance for the food, cosmetic, and pharmaceutical industries. They are not only responsible for capturing solar energy to carry out photosynthesis, but also play a role in photoprotective processes and display antioxidant activity, all of which contribute to effective biomass and oxygen production. Diatoms are organisms of a distinct ...
