  • Title: [Biological fixation of nitrogen and growth of bacteria of the genus Azotobacter in liquid media in the presence of perfluorocarbons].
    Author: Bakulin MK, Grudtsyna AS, Pletneva AIu.
    Journal: Prikl Biokhim Mikrobiol; 2007; 43(4):443-9. PubMed ID: 17929572.
    Abstract:
    The addition of perfluorocarbons (perfluorodecalin, carbogal, and perfluoromethyldecalin) to nitrogen-free liquid media during the submerged cultivation of bacteria of the genus Azotobacter was followed by (1) increases in biomass accumulation and nitrogenase activity and (2) fixation of molecular nitrogen. Addition of perfluorodecalin (5 vol %) to the culture medium of A. chroococcum ACB 121 contributed to increases in biomass accumulation, cell concentration (of more than by five times), nitrogenase activity (of 3.4 times), and total nitrogen content in the medium (of 4.5 times).
