KYARII RAMARUI is an academic who published a paper in 2019 entitled IMPROVING HAEMATOCOCCUS PLUVIALIS GROWTH AND ASTAXANTHIN PRODUCTION THROUGH CHEMICAL MUTAGENESIS. KYARII RAMARUI published this work as part of a team: Ramarui, Kyarii. Here is a description of this work: Astaxanthin is a keto-carotenoid known for its strong antioxidant activity. It is widely used in the aquaculture and nutraceutical industries. Haematococcus pluvialis has long been used as a natural source of astaxanthin, however, its slow growth rate creates a production bottleneck. To overcome this bottleneck, Haematococcus mutants with improved growth rate under heterotrophic culture conditions were generated. This was achieved through screening for mutants with improved acetate catabolic rates. An ethyl methanesulfonate based chemical mutagenesis approach was used to generate Haematococcus mutants. Two mutants, YLEMS 3L-33 and KREMS 23D-3, were identified after three rounds of screening, which showed 75% and 21% higher biomass concentrations than the wild type under heterotrophic growth conditions, respectively.
