Introduction
- Klebsormidium nitens NIES-2145 The charophytic algae Klebsormidium nitens strain NIES-2285 (formerly identified as K. flaccidum) usually consist of multicellular and non-branching filaments without differentiated or specialised cells.
Each cell has a large chloroplast lying against cell wall (parietal chloroplast). pyrenoid surrounded by a few starch grains.
