These AstaPs are classified as a novel family of carotenoprotein and are useful for providing valuable astaxanthin in water-soluble form; however, the distribution of AstaP orthologs in other microalgae remains unknown. Here, we exam- ined the distribution of AstaP orthologs in the family Scenedesmaceae with two model microalgae, Chlamydomonas reinhardtii and Chlorella variabilis.

Distribution and ecological habitat of Scenedesmus and related genera in some freshwater resources of Northern and North-Eastern Thailand. Biodiversitas 18: 1092-1099. The family Scenedesmaceae is made up of freshwater green microalgae that are commonly found in bodies of freshwater, particularly in water of moderate to polluted water quality. However, as of yet, there have not been any studies on the diversity of this family in Thailand and in similar regions of tropical areas. Therefore, this research study aims to investigate the richness, distribution and ecological conditions of the species of the Scenedesmus and related genera through the assessment of water quality. The assessment of water quality was based on the physical and chemical parameters at 50 sampling sites. A total of 35 taxa were identified that were composed of six genera, i.e. Acutodesmus, Comasiella, Desmodesmus, Pectinodesmus, Scenedesmus and Verrucodesmus. Eleven taxa were newly recorded in Thailand. -

Comparison with the same species from alpine soils in Tyrol (Austria) was done and the establishment of C. aeroter- restrica as a good species was proved. It is supposed that further careful investigations of algal cul- tures from soil will reveal the broader distribution of both species in Bulgaria and other countries in Europe.

Introduction: The earliest investigation of the soil algae in Bulgaria could be traced back to the end of 19th century, when Botrydium granulatum (GREV.) FISCHER was recorded by PETKOFF (1898-1899). Since then 228 species, 17 varieties and 10 forms of soil algae have been reported for the country by different authors (detailed list of references and taxa is availa- ble in UZUNOV et al. -
