    Notes: Abstract Anabaena azollae (AS-DS), isolated from Azolla filiculoides and grown in nitrogen-free medium, was immobilized in 5-mm-cube polyvinyl foam pieces and incorporated into a photobioreactor system for the production of NH3. NH3 was produced continuously and in significant amounts. Benlate (methyl-1-butyl-carbamoyl)-2-benzimidazole carbamate at 5 ppm and l-methionine-d,l-sulphoximine at 50 μm stimulated NH3 production continuously for a period of 1 week.

    Inhibition ofAzorhizobium andRhizobium by seed leachates (1992)
    Springer
    World journal of microbiology and biotechnology 8 (1992), S. 542-543 
    Details
    ISSN: 1573-0972
    Keywords: Azorhizobium ; inhibition ; Rhizobium ; seed leachates ; Sesbania ; stem nodule
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract During germination of seeds ofSesbania rostrata, S. aculeata andS. speciosa various constituents, including tannin, free amino acids, protein, nitrogen and sugars, were released. Tannin released byS. speciosa after 24 h was particularly high. The growth ofAzorhizobium andRhizobium were inhibited in the presence of these materials.

    Effect of immobilization of cyanobacteria in solid matrix on ammonia excretion and nitrogen fixing activity (1993)
    Springer
    Biotechnology letters 15 (1993), S. 975-978

    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary The algal symbiont of Azolla - Anabaena azollae (AS-DS) and free-living A.variabilis (SAo) colonized and immobilized well in all the solid matrices such as hollow fibre, polyurethane foam, cotton and silk cotton. Biomass production was more under immobilized state than under free-living state. Heterocyst frequency, nitrogen fixing activity and ammonia excretion were significantly higher under immobilized state than under free-living conditions.
