SECTION II. APPLIED BIOTECHNOLOGY IN THE PHARMACEUTICAL INDUSTRY... 401fertilizers and biological preparations for soil improvement in both models compared to pre-application levels. In model 2, after four months of planting and caring for peanuts, the density of beneficial microorganisms was 7.24 %u00d7 107, the density of nitrogenfixing microorganisms was 1.75 %u00d7 107, phosphate-dissolving microorganisms was 2.81 %u00d7 106 and cellulose-decomposing bacteria was 7.3 %u00d710 6. The densities of beneficial microorganisms were all lower than in model 2. Specifically, the density of beneficial microorganisms was 6.86 %u00d7 106, nitrogen-fixing microorganisms was 1.45 %u00d7 106, phosphate-dissolving microorganisms was 2.04 %u00d7 106 and cellulose-decomposing bacteria was 1.71 %u00d7 106.Figures 2.
