Method Abstract: "Here [investigators] describe Synechococcus elongatus UTEX 2973, a unicellular cyanobacterium capable of rapid autotrophic growth, comparable to heterotrophic industrial hosts such as yeast."
Comments P.2 left column bottom paragraph: "Growth of Synechococcus UTEX 2973 was assessed under different conditions and the shortest doubling time was 1.9 hrs in BG11 medium [primary source] at 41°C under continuous 500 μmoles photons·m^−2·s^−1 white light with 3% CO2. This is a remarkably high growth rate under autotrophic condition, the highest rate reported to date for a cyanobacterial strain, and comparable to heterotrophic growth rates of the yeast S. cerevisiae."
