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 to right column top paragraph: "A direct result of such a rapid growth property is that a dilute culture of Synechococcus UTEX 2973 accumulated substantial amounts of biomass within a 16 h time period. In contrast, a Synechococcus PCC 7942 culture was still dilute when both cultures were grown under their respective optimal conditions (Fig. 1B). Similar results were obtained for biomass accumulation of these two strains. The dry weight of Synechococcus UTEX 2973 increased from 0.13 ± 0.01 mg/ml at the beginning of the experiments to 0.87 ± 0.03 mg/ml after 16 hours, while the dry weight of Synechococcus PCC 7942 changed from 0.12 ± 0.02 mg/ml to 0.33 ± 0.03 mg/ml during the same period of time. As shown in Fig. 1C, a high level of illumination as well as CO2 are important factors to support rapid growth of Synechococcus UTEX 2973 (Fig. 1C)."
