Figure 4From: Molecular and bioengineering strategies to improve alginate and polydydroxyalkanoate production by Azotobacter vinelandiiInfluence of the dissolved oxygen tension (DOT) on the molecular weight distribution of the alginate obtained with A. vinelandii SML2 strain. Dotted line 7 h, dashed line 13 h, solid line 21 h y 16 h (for 1% and 3–5 % of DOT respectively). Taken with permission from Trujillo-Roldán et al. [69].Back to article page
