Diatoms and Flocculent Matter

Phosphomannans and other components of flocculent and non-flocculent walls of Saccharomyces cerevisiae.

Photo-dissolution of flocculent, detrital material in aquatic environments: contributions to the dissolved organic matter pool.

This study shows that light exposure of flocculent material (floc) from the Florida Coastal Everglades (FCE) results in significant dissolved organic matter (DOM) generation through photo-dissolution processes. Floc was collected at two sites along the Shark River Slough (SRS) and irradiated with artificial sunlight. The DOM generated was characterized using elemental analysis and excitation em...

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...

Diatoms: an ecoregional indicator of nutrients, organic matter and micropollutants pollution

Diatoms are extremely diverse ubiquitous microalgae. This makes them good indicators of the quality of aquatic ecosystems, and they have been used for this purpose for the past 50 years. Since 2000, the European Water Framework Directive has required them to be used for assessing the ecological quality of watercourses. A typological framework has to be devised in order to compa...
