  1. Strains are arranged in descending order of biomass productivity (gC l−1 d−1) focussing on best strains for a given species/genus. Scoring system refers to productivity: >95th percentile (+++); >90th percentile (++) and >70th percentile (+) except for N-assimilation where this indicates high assimilation of supplied N. All tested under full-salinity culture unless indicated (*) where freshwater.
  2. Commercial origin (see Supplementary Dataset S1 online). Full data found in Supplementary Dataset S4-S7 online. ω-3’s: omega-3 long-chain PUFAs.
