Meiosis aparentemente zigóticas. The unicellular microalga Haematococcus pluvialis has emerged as a promising biomass feedstock for the ketocarotenoid astaxanthin and neutral lipid triacylglycerol. Algunas colecciones de cultivos que cuentan con cepas son: Un uso muy común que se le da a esta Chlorophyta es para piensos en acuicultura y acuariofilia. The main cell proliferation, both in the motile phase and non-motile phase in H. pluvialis, is by asexual reproduction. Rio de Janeiro: Andrea Jakobsson Estúdio; Instituto de Pesquisas Jardim Botânico do Rio de Janeiro. Algal cells were cultured in 100 ml of basal medium ( Kobayashi et al. 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). Its typical astaxanthin content is 1.5–3.0% dry weight [].Under certain conditions, the astaxanthin content can be as high as 5–6% dry weight [].H. Green motile stage is the 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). i-xiii, 1-977. Collins AM, Jones HDT, Han D, Hu Q, Beechem TE, et al. Phycologia 45: 616-623. Se halla en cursos de agua estacionales. In this study, we compared the differences between motile cells and nonmotile cells in astaxanthin productivity, morphological changes, the mortality rate, and the diameter of the formed cyst… 4. Haematococcus has two distinct phases in its life cycle, vegetative growth phase and encysted secondary carotenoid accumulation phase.

Haematococcus pluvialis is a freshwater unicellular green microalga belonging to the class Chlorophyceae and is of commercial interest for its ability to accumulate massive amounts of the red ketocarotenoid astaxanthin (3,3′-dihydroxy-β,β-carotene-4,4′-dione). Striped plates (SP) of irregular shape are connected via non-regular-shaped defective zones (DZ) and are overlain by a fibrillar layer (FL). Joo, Hyun-Na, y Choul-Gyun Lee. In this study, we initiated the application of near‐infrared spectroscopy (NIRS) in the analysis of total biomass and astaxanthin content of different mutant strains, demonstrating that NIRS can be very useful in the screening of axataxanthin‐hyperproducing mutant strains. Pham, M.N., Tan, H.T.W., Mitrovic, S. & Yeo, H.H.T. Griseofulvina y ampicilina no afecta al metabolismo y crecimiento del alga, así como la Cefalosporina y la amfotericina B sí lo hacen, ocasionando que la célula se enquiste. The size of the nonmotile cells and the number of daughter cells formed within was inversely proportional to the growth rate of the cultures. C. Brown. Haematococcus was first described by J.
