“…Parallel experimental studies showed that the addition of a vitamin mix promoted cell growth in our strain (Mazumdar et al. ,b). However, the presence of B 1 (thiamine HCl), B 12 (cyanocobalamin), and B 7 (biotin) in MLA medium would increase large scale cultivation costs.…”

“…Morphological and phylogenetic studies based on 18S ribosomal (r) RNA, internal transcribed spacer (ITS) rRNA, rbc L genes showed that the strain is a new species (Mazumdar et al. ,b), with the validly published name H. alpinus . This species was morphologically distinct from others by location, number, and thickness of cytoplasmic strands.…”

The present study investigated the effect of different culture conditions on the vegetative growth of a new species, Haematococcus alpinus (strain LCR‐CC‐261f) using airlift photobioreactors. The influence of culture medium, aeration rates, CO2 concentration in air‐gas mixture, temperature, light intensities, and wavelengths were investigated to achieve sustainable high cell density cultures. Growth parameters were determined by fitting the data to a form of the logistic equation that included a lag phase. The shear‐sensitive vegetative cells favored lower aeration rates in the photobioreactors. MLA medium increased to 40 mM nitrate produced high density cultures. Temperatures between 12°C and 18°C, 3% (v/v) CO2 concentration and a narrow photon flux density ranging between 37 and 48 μmol photons · m−2 · s−1 were best suited for growth. The wavelength of the light source also impacted growth and a high cell density of 9.6 × 105 cells · mL−1 was achieved using a mixture of red and blue compared to warm white, red, or blue LEDs.

SUMMARY The microalga Haematococcus lacustris is a source of astaxanthin used widely in aquaculture, pharmaceutical, and cosmetic industries. A new strain of Haematococcus (LCR‐26C‐1f) isolated from the New Zealand alpine zone was evaluated in this study. The influence of vitamins, micronutrients, various carbon and nitrogen sources were investigated to maximize biomass production in batch cultures using shake flasks. Supplementation of vitamins consisting of thiamine, biotin, and cyanocobalamin improved the cell density by 40% over the vitamin‐free medium. Out of the individual vitamins tested, thiamine was shown to be necessary to maintain high cell densities. The best nitrogen source tested was nitrate in the form of sodium nitrate, at a 40 mM concentration. Heterotrophic growth yielded much lower cell densities compared to autotrophic growth. The micronutrients iron and manganese were essential for growth. However, the best growth was obtained using a micronutrient mix that included iron, copper, cobalt, zinc, manganese and molybdenum.
