  • Method for discovering algal strains with reduced pigment to attain higher photosynthetic efficiency
    Patent number: 9528138
    Abstract: A method for determining and/or engineering photosynthetic mutant algal strains comprising: (A) pre-screening wild-type or parent strains to select for photosynthetic efficiency; (B) cause genetic mutations in the group of wild-type and/or parent strains from pre-screening (A) to form genetic mutant strains; (C) screening the genetic mutant strains for photosynthetic efficiency in mass cultures; and (D) further screening the genetic mutants resulting from screening (C) by measuring biomass productivity to select strains having relatively high biomass/lipid/starch productivity.
    Type: Grant
