Ultrastucture of the cyst wall of Haemotococcus pluvialis (Chlorophyceae): wall development and behaviour during cyst germination. Haematococcus pluvialis has quite complex life cycle consisting of four life stages, biflagellated zoospores, non- motile round palmella stage, thick-walled akinetes (aplanospores, cysts) with high content of astaxanthin and small biflagellated gametes. ABSTRACT Freshwater microalgae, Haematococcus pluvialis (H.pluvialis), has been a topic of research since the mid-19th century. Haematococcus pluvialis es un alga verde con crecimiento mixotrófico, pero eminentemente fotoautótrofo. Rio de Janeiro: Andrea Jakobsson Estúdio; Instituto de Pesquisas Jardim Botânico do Rio de Janeiro. The life cycle of H. pluvialis consists of four types of distinguishable cellular morphologies: macrozooids (zoospores), microzooids, palmella, and hematocysts (aplanospores) (Hazen, 1899; Elliot, 1934). Este alga tiene un interés biotecnológico creciente gracias a su acumulación de astaxantina y al alto valor económico que presenta esta en el mercado. Cloroplastos en forma de copa, en ocasión tubulares, con 1,2 (o varios) pirenoides y un estigma de gran tamaño. Haematococcus pluvialis is a unicellular green alga and is considered as the best natural resource for astaxanthin, which is a high-value carotenoid with strong biological activity for the food, feed, and pharmaceutical industries (Ambati et al. Cultivos aislados de Haematococcus pueden crecer en condiciones heterotróficas en oscuridad usando nitrógeno orgánico y acetato como fuente de carbono. Haematococcus was first described by J. Haematococcus pluvialis is one of the most abundant sources of natural astaxanthin as compared to others microorganism. La astaxantina es segregada como una forma de proteger el fotosistema cuando la célula percibe que las condiciones no son favorables y desencadena la respuesta de enquistamiento. (1961).
