Las células vegetativas con frecuencia se convierten en aplanosporas con paredes gruesas que producen zoosporas. Astaxanthin from H. pluvialis is an antioxidant and presents a promising application in medicine for human health. However, cell death and low astaxanthin productivity have seriously affected the stability of astaxanthin production. The present paper summarizes the available information on nomenclature, taxonomy, morphology, life cycle and ultra-structure, which have so far been left out of the many reviews on this interesting alga. The motile vegetative cells are more sensitive to stress than nonmotile vegetative cells, thereby affecting the overall astaxanthin productivity in H. pluvialis cultures. Hu, H. & Wei, Y. Haematococcus pluvialis[3]​ es un alga verde de agua dulce, unicelular, de la familia de las Haematococcaceae. Fig. We quantified the initial and total enzyme activity of ribulose-1,5-bisphosphate carboxylase (Rubisco) in crude extracts, and the relative expression of large-subunit ribulose-1,5-bisphosphate caboxylase / oxygenase ( rbcL) mRNA. Environ. The current commercial production of natural astaxanthin is mainly carried out using Haematococcus pluvialis vegetative cells in the “two-stage” batch mode. (2013). 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). The main cell proliferation, both in the motile phase and non-motile phase in H. pluvialis, is by asexual reproduction. Haematococcus has two distinct phases in its life cycle, vegetative growth phase and encysted secondary carotenoid accumulation phase. Haematococcus pluvialis is a freshwater species of Chlorophyta from the family Haematococcaceae.This species is well known for its high content of the strong antioxidant astaxanthin, which is important in aquaculture, and cosmetics. We measured the ratio of photosynthetic rate to respiration rate … Prescott, G.W. 1992). C. Brown.
