La mayor parte del protoplasto está internamente separado de la pared celular y, que se conecta por delgados hilos que pueden ser simples o ramificados. Collins AM, Jones HDT, Han D, Hu Q, Beechem TE, et al. The life cycle of H. pluvialis contains two distinct phases, namely a green motile vegetative phase and a non-motile astaxanthin-accumulating cyst phase (Sarada et al., 2006). Each algal cell stage could be distinguished by the ratio of pigments (carotenoid/chlorophyll) and the intracellular protein content. This is due to its excellent ability to synthesize a very valuable bioactive molecule called astaxanthin which has a plethora of applications in food and pharmaceutical sectors. Bacau. ABSTRACT Freshwater microalgae, Haematococcus pluvialis (H.pluvialis), has been a topic of research since the mid-19th century. Haematococcus pluvialis is a freshwater species of green algae and is well known for its accumulation of the strong antioxidant astaxanthin, which is used in aquaculture, various pharmaceuticals, and cosmetics. Posee clorofila a y b, y tiene la capacidad de sintetizar carotenoides como la Astaxantina que puede llegar a acumular en una proporción de incluso un 5% de su peso seco. All the cells can be classified into forms as follows: motile cell, nonmotile cell, zoospore and aplanospore. Se realizó una revisión bibliográfica de 15 artículos científicos, en donde se evaluaron diferentes condiciones de cultivo y factores de estrés con el propósito de mejorar la acumulación de astaxantina en H. pluvialis . The Haematococcus encysted cell wall consisted of 70% carbohydrates (66% hexoses), 3% cellulose, and 6% proteins … (1961). H. pluvialis is common in small transient freshwater bodies and widely distributed in many habitats worldwide. Under these optimum conditions, the astaxanthin yield was 73.9% (10.92 mg/g dry H. pluvialis powder) after eight cycle of extraction cycles. (2) Illustration of life cycle of H. pluvialis. Haematococcus pluvialis (H. pluvialis) es una de las fuentes más importante de astaxantina, tiene un gran interés comercial debido a su poderosa actividad antioxidante.

The microalga Haematococcus pluvialis was cultured with NaNO 3 from 0 to 1 g l−1 and optimal growth was obtained at 0.15 g l−1. H. pluvialis occurrence has been reported in different water bodies like artificial pools, natural and manmade ponds [19,20] and has been isolated from different regions of Europe, Africa, North America, and Himachal Pradesh India [21, 22]. It is considered as the best natural source of astaxanthin and the main producing organism of this commercial product (Lorenz, 1999; Ranga Rao et al., 2010). The current commercial production of natural astaxanthin is mainly carried out usingHaematococcus pluvialis vegetative cells in the “two-stage” batch mode. Este tipo de respuesta le confiere la ventaja de ser muy resistente a multitud de factores ambientales como radiaciones de alta energía, frío extremo, tóxicos, etc. H. pluvialis was cultivated in BG-11 medium for 12 days under irradiation of white plasma light, blue LED light and red LED light. Caraus, I. 2014). High levels of astaxanthin are present in cysts, which rapidly accumulate when the environmental conditions become unfavorable for normal cell growth. 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.
