Submerged culture of M. gryphiswaldense ∆F-FA in 42-L fermentor: Cmag, dO₂, and cell growth. a Cmag and dO₂ values as a function of time. Cmag began rising above zero only after dO₂ fell below 1%. b Growth curve. Cell density is estimated by OD₅₆₅. Maximal Cmag value was 0.68. Maximal OD₅₆₅ was 7.91. Total dry weight of collected cells was 67.8 g
