Nitzschia bacillum is a small, rod-shaped pennate diatom with a cylindrical outline and a keel-positioned raphe. It inhabits benthic substrates in rivers, streams, and lakes across temperate and subtropical regions worldwide. This photosynthetic diatom forms part of the attached microalgal biofilm community in diverse freshwater environments.

Nitzschia tenuis is a slender, elongated diatom found in freshwater, brackish, and marine environments worldwide, tolerating a wide range of salinity and nutrient conditions. Its fine, needle-like frustule is characteristic of many Nitzschia species. This diatom contributes to aquatic primary productivity and is commonly encountered in periphyton, plankton, and sediment communities.
