ISOLATION AND SCREENING OF ZINC MOBILIZING MICROORGANISMS FROM RHIZOSPHERIC SOIL

Komal Rudani, Kalavati Prajapati

Abstract :

Interaction between soil microbes and minerals play a major role in environmental cycling–processes, which leads to the mobilization of nutrient from soil components into available forms for biological uptake which enhances growth and yield. In the present study zinc mobilizing bacteria (ZnMB) and zinc mobilizing fungi (ZnMF) were isolated from garden soil and rhizosphere soil collected from kadi region. The colonially and morphologically diverse bacterial and fungal cultures showing solubilization zone for zinc oxide (ZnO) and zinc carbonate (ZnCO₃) were isolated. The isolated bacterial (ZMB) and fungal (ZMF) isolates were screened for solubilization of insoluble zinc sources i.e. Zinc oxide (ZnO) and zinc carbonate (ZnCO₃). These isolates were then characterized on the basis of morphological, cultural characteristics, enzyme spectrum and sugar utilization. Among the primary screened bacterial and fungal isolates which show maximum zone of Insoluble zinc solubilization were selected for further study.
