Identification of Suitable rhizobacterialspecies for Fluoride Contaminated Areas: A Comparative Growth Kinetics Study

Sheetal Trikha, R. S. Chundawat

Fluoride, not considered as a major toxicant earlier but now it is increasing very rapidly in soil. Rhizobacteria plays an important role in maintaining soil health and geo-chemical cycles. Previous studies indicate its effect on many enzymes affecting biochemical pathways, energy metabolism and growth at cellular levels. This study aimed to find out the best suitable rhizobacterial species for fluoride contaminated areas by comparing their growth kinetics and resistance to fluoride absorption. 19 rhizobacterial species were selected and allowed to grow in the presence of 15 ppm fluoride. Growth kinetics and movement of fluoride from media to bacterial cells was monitored at different time intervals. Comparative growth fluctuation in presence of fluoride and respective control clearly indicates the significant interference of this mineral in rhizobacterial activity. Statistical analysis of data clearly indicates that P10 followed by P13 and P8 species can be more effective in improving soil health without using chemical fertilizers for fluoride contaminated areas.
