Proteomic and phosphoproteomic analysis of a Haematococcus pluvialis (Chlorophyceae) mutant with a higher heterotrophic cell division rate reveals altered pathways involved in cell proliferation and nutrient partitioning.

Abstract excerpt

Haematococcus pluvialis has been used to produce the ketocarotenoid antioxidant, astaxanthin. Currently, heterotrophic cultivation of H. pluvialis is limited by slow growth rates. This work aimed to address this challenge by exploring the mechanisms of acetate metabolism in Haematococcus. Chemical mutagenesis and screening identified H. pluvialis strain KREMS 23D-3 that achieved up to a 34.9% higher cell density...
