Abstract

The present study was carried out to analyze the impact of arsenic (As) resistant bacteria (BBAU/CH) on the growth and mineral status in rice plants treated with As(III).Results revealed that rice plant supplemented with As resistant bacteria (BBAU/CH) enhances the plant growthin the form of root length(17%) and shoot length (9.80%) as compare to control. The mineral status in grain of As(III) (high dose) treated rice exhibited alteration in mineral content and showed maximum reduction was observed in Se(39.25%) while minimum in Cu (16.62%), which further recovered bythe application of bacterial inoculants. Thus, bacterial strain (BBAU/CH)may be used as potent bioremediator in the maintaining nutrient status of rice grown in As contaminated land.
