Efficient phosphorus solubilization by mutant strain of Xanthomonas campestris using different carbon, nitrogen and phosphorus sources
Autor: Nandan Singh Darmwal, Adhyayan Sharan, Shikha
Publikováno v: World Journal of Microbiology and Biotechnology. 24:3087-3090
The phosphate solubilization activity of Xanthomonas campestris was measured in both the wild type and mutant strains using various carbon and nitrogen sources. Glucose was found to be the best in both (wild 39.9%; mutant 67.1%) strains followed by s

Xanthomonas campestris, a novel stress tolerant, phosphate-solubilizing bacterial strain from saline–alkali soils
Autor: Nandan Singh Darmwal, Rajeeva Gaur, Adhyayan Sharan, Shikha
Publikováno v: World Journal of Microbiology and Biotechnology. 24:753-759
A total of 198 bacterial strains were isolated from various niches of saline–alkali soils, out of which 85 strains were able to solubilize phosphate on plates at 30 °C. The strain RMLU-26, identified as Xanthomonas campestris, was the most efficie
