Enhancement of cell biomass and cell activity of astaxanthin-rich Haematococcus pluvialis
Abstract
Fed-batch culture and the transformation conditions of Haematococcus pluvialis in a 5L photobioreactor were investigated. Methods of feeding model, low temperature at night and proper feeding time were used to increase both cell biomass and cell activity. Dry cell weight of 1.87 g/L which was 2.0-fold of batch culture and the specific growth rate of 0.43 d(-1) suggested the superduper results of these methods to increase the dry cell weight in the short cultivation time. Furthermore, mixed lights of blue and white (ratio of 3:1) at 7000 xl were used to expedite the morphologic changes of H. pluvialis from green cells to red cyst cells with the yield of 91.8±2.53 mg/L.

Haematococcus pluvialis produces astaxanthin up to 50 mg g−1 dry biomass under stress conditions.
“For instance, Haematococcus pluvialis, known for its high astaxanthin content, has demonstrated production levels of up to 50 mg g−1 of dry biomass under stress conditions [11].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
