[Influence of natural minerals on growth of Azotobacter vinelandii IMV B-7076]
Abstract:
It was shown that the cultivation of Azotobacter vinelandii IMV B-7076 in the presence of natural minerals significantly increased the growth of bacteria activity. Adding in the medium glauconite and saponite in optimal concentration (10 g/l) conditioned the increase of cell growth six and four times compared with control, accordingly. The maximum stimulating effect was observed when the concentration of phosphates was 5.0 g/l, herewith the number of viable cells increased 5 times. The presence of contact interaction of bacterial cells with investigated particles minerals was shown.
