Cultures of bluE and bluB grown in 50 ml for 26 hr from different inoculum volumes as indicated. Note the orange color of the cultures grown from smaller inocula due to accumulation of MPE. The progressively more purple color of larger inocula is due to BChl and carotenoid formation, attributed to vitamin B₁₂ in the inocula.
