1. Scientists were working with a microbe called Azotobacter vinelandii, which is found around the roots of various food plants.

2. The compound fertilizer improved the population of azotobacter and potassium bacteria, and the phosphate ammonium enhanced the population of phosphobacteria.

3. The paper introduces the method of making azotobacter fertilizer by biological process and test method of bacteria.

4. The paper introduces the method of azotobacter fertilizer by biological process and test method of bacteria.

5. As to same tea age,[sentencedict .com] the population of azotobacter became smaller with the soil fertility decrease.

6. The number of aerobic azotobacter decreased with the successive cropping years increasing but was higher than CK and as 311.21%, 120.77% and 46.07% times as CK respectively.

7. Bacterial ferritin from Azotobacter vinelandii has qualitative characteristic absorption peaks in the visible spectral region.

8. The studies on the effects of Azotobacter N16 culture liquid in different culture period on its growth indicate that upper liquid and serums can accelerate the growth of N16.

9. The numbers of bacteria, azotobacter and fungi were highest in spring.

10. Quite the opposite: they are willingly accepted by a diverse range of microbes, from Proteus and Azotobacter to E. coli.

11. Al was significantly poisonous to soil nitrifier, dinitrifier and azotobacter at high concentration, and the maximum inhibition ratio reached 96%, 98% and 89%, respectively.

12. Under the same condition, compared with the control group, the shelf life of Azotobacter can be extended to over 12 months and that of Bacillus phosphaticum is more than doubled.

13. The results showed that the roots of three species of tea exert a positive rhizosphere effect on the phosphobacteria and postassibacteria, and negative rhizosphere effect on the Azotobacter.

14. The Cyanobacteria (blue green algae) and soil bacteria such as Azotobacter, which carry out BNF without plant involvement, are examples of free - living nitrogen fixing organisms.

15. Add 4% molasses and 2% wheat bran to the Azotobacter, the shelf life of Bacillus phosphaticumicum or Bacillus mucilagionsus solution can be significantly improved.

16. It reveals that the remediation increases the quantity of bacteria and azotobacter which is propitious to increase the soil fertility.

17. In this paper, under laboratory condition , the dynamic influence of both single and combined pollution of carbofuran and cadmium on the number of azotobacter was studied.
