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 graciliformis is a slender, needle-shaped pennate diatom found in freshwater and brackish aquatic habitats including streams, lakes, and coastal waters worldwide. Its elongated siliceous frustule bears a distinctive raphe system along one side, enabling gliding motility. This species contributes to aquatic primary production and is used in freshwater biomonitoring due to its sensitivity to nutrient levels.
