Adaptive сharacteristics of Azotobacter chlorococcum Beiyrinck and Bacillus mycoides Flugge in soils of the city

Results of researches of growth plants and bacteria in urban soils of territory of West Ural are presented. Found content rolling P and K in surface layer soil their influence on biomass plants and plenty of bacteria. It is shown, that Azotobacter culture grows in soils analyzed in different ways, the difference observed in the growth rate, the diameter of the colonies, the antagonistic activity. The changeability of colonies of Azotobacter chroococcum and Bacillus mycoides was determined. It speaks about adaptations of bacteria in specific habitats.
