A unicellular red microalga was isolated from environmental freshwater in Korea, and its morphological, molecular and biochemical properties were characterized, respectively. Morphological analysis revealed that the isolate was biflagellated unicellular green microalga with forming a non-motile, thick-walled palmelloid or red aplanospore. To determine the taxonomical position of the isolate, 18S rRNA and rbcL genes were sequenced and its phylogenetic analysis was conducted, and the results revealed that the isolate was clustered together with other related Haematococcus strains with showing differences in the rbcL gene. Therefore, the isolated microalga was classified into the genus Haematococcus, and finally designated as Haematococcus sp. KORDI03. The microalgae could be cultivated in various culture media under broad range of pH and temperature conditions. Compositions of the cellular components of the microalgae were further analyzed, and its protein, @entity1735 and lipid compositions were estimated to be 21.1  0.2 %, 48.8  1.8 % and 22.2  0.9 %, respectively. In additions, @entity413 and @entity3913 were found as the dominant mono-saccharides in the isolate, and its @entity1522 were mainly composed of @entity2574 , @entity367 , @entity493 and @entity368 . Moreover, several @entity1474 ( @entity5204 ) comprised about 80% of the total @entity1718 in Haematococcus sp. KORDI03, and its @entity20467 content in red aplanospore was estimated to be 1.8% of the dry cell weight. To our knowledge, this is the first report of Haematococcus sp. isolated from Korea, and the isolated strain will have a potential for bioresource production in microalgal industry.
