| Growth and Photosynthesis of Nanochlorum eucaryotum, a New and Extremely Small Eucaryotic Green Alga  | | | | Abstract
| Nanochlorum eucaryotum is a very small species o f unicellular coccoid green algae (1.5 nm). The growth of Nanochlorum under different conditions o f salinity, pH and light intensities was studied. Optimal growth rates were observed with normal sea water salinity and low light conditions at pH 7.0. The contents o f chlorophylls, carotinoids, soluble proteins and the chlorophyll a to chlorophyll b ratio were measured. The light saturating curves of Nanochlorum cells grown under light intensities o f 100 lx, 2000 lx and 10000 lx reveal a very narrow capacity of light adaptation. When cultured under higher light intensities, Nanochlorum was not able to reach high photosynthetic activities but underwent a photoinhibition o f photosynthesis. The contents of cytochrome f, P-700 and ribulosebisphosphate carboxylase were low and comparable with those of low light adapted Chlorella cells. The analysis o f the chlorophyll-protein complexes shows that about 80% o f total chlorophyll is bound in the light harvesting chlorophyll protein complexes. All results indicate that Nanochlorum is a low light adapted marine organism with very narrow ecological flexibility. | | | |
