Figure 2From: Oxygen transfer rate during the production of alginate by Azotobacter vinelandii under oxygen-limited and non oxygen-limited conditionsEvolution of the oxygen transfer rate (a), cell growth (b), alginate production (c) and sucrose consumption (d) in cultures of Azotobacter vinelandii grown under non oxygen-limited conditions (5%) at 300 (■) and 700 rpm (●). Cultures were kept at a temperature of 29°C and the airflow rate was of 1.0 L min-1.Back to article page
