Claim Text:
1. 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 by (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 by (D) further screening the genetic mutants resulting from screening (C) by measuring biomass productivity to select strains having relatively high biomass productivity, measured as ash-free dry weight per volume of culture per unit time and/or as ash-free dry weight per area of illuminated surface of the culture per unit time, at least 25% higher than that of the corresponding wild-type and/or parent strains.
