APPLIED MICROBIAL TECHNOLOGY: SOLUBILIZATION OF INORGANIC PHOSPHATE AND PRODUCING SIDEROPHORE BY ISOLATED NITROGEN FIXING BACTERIA. Autori: SZABOLCS LÁNYI. |

Rezumat: The benefic microbes play an important role in the transformation, mobilization and solubilization of the nutrient content of the soils. Their nitrogen fixing ability to in symbiosis with legume has a central role in the nitrogen-cycle of most natural ecosystems. A total of 30 bacteria were isolated from different leguminous plants nodules and rhizospheric soils. The morphological and biochemical characterization of these isolates was made and they was screened for their plant-growth promoting factors: tricalcium phosphate mobilization capability and siderophore productivity by agar plate method. Some A of these bacteria were classified genotypicaly.
Keywords: leguminous plant, inorganic phosphate, siderophore production. |
