Galdieria sulphuraria

This alga is able to grow at pH 2. In Chlamydomonas reinhardtiiit was recently reported that phosphorus depletion substantially induces accumulation of lipid droplets in the cytosol while maintaining thylakoid membranes Iwai et al.

Conceived and designed the experiments: Five hundred microliter of the neutralized water sample were transferred into a 1. These results suggest that G. Published online Dec Nitrogen-starvation-induced chlorosis in Synechococcus PCC No use, distribution or sulphiraria is permitted which does not comply with these terms.

It is the type species of the genus Galdieria. Thus, the preference in types of nitrogen sources depends baldieria other factors in the media and it will be different for cultivation in spring water from cultivation in synthetic media. Thus, the combination of acidophilic algae in acidic natural wastewater will be one strategy applied to open pond culture systems for commercial use or bioremediation in the future.
