Fig. 2From: Aerobic-anaerobic transition boosts poly(3-hydroxybutyrate-co-3-hydroxyvalerate) synthesis in Rhodospirillum rubrum: the key role of carbon dioxideDifferent conditions of the experimental set-up. (A) Scheme of the experimental set-up. Open (O) and close (C) systems were established by using cotton or rubber plugs in order to control the exchange of gas with the atmosphere. The aeration levels were also controlled with the agitation (100 rpm or 200 rpm) and the filling volume (1/5 or 1/2). Medium in AL condition was degassed with N2 before autoclaving. All the condition, with the exception of AL, were grown in darknessBack to article page
