Caption: Light microscope footage of Haematococcus pluvialis algae, showing the biflagellate cells moving in the water column. Haematococcus (from the Greek haima , blood and kokkos , berry) occurs as biflagellate unicells where the protoplast is connected to the wall by multiple, thin strands of cytoplasm. Cell structure and reproduction appear to be similar to those of Chlamydomonas. In this sample the most of the shown cells are relatively young, showing the green colour of the chloroplast without the overlay of accumulated Astaxanthin at the beginning of formation of resting stages. Mass reproduction often forms conspicuous red to deep-purple growths, based on accumulation of astaxanthin during formation of resting stages. Astaxanthin is commercially valuable as a food colorant and in cosmetic products. Microscopic contrast method used: differential interference contrast. Captured field width: 0.17 mm. Sample taken from of an algae culture of the culture collection of algae at the university of Cologne, CCAC.
