Rhizosphere Interactions of Bacillus pumilus Regulating Heavy Metal Transport and Detoxification in Cabbage

Abstract

Increasing the number of heavy metals on land needs to be addressed through sustainable ways and various species of Bacillus can be used to mitigate heavy metals. The research work entitled “Effect of Bacillus pumilus strains on heavy metal accumulation in cabbage grown on contaminated soil” focuses on functional role of Bacillus pumilus strains inoculated with cabbage seed in mitigating heavy metal present in chromite mining soil. This experiment was conducted at ornamental horticulture nursery, the University of Agriculture Peshawar. In this experiment, factor A was three Bacillus pumilus strains (sequence C-2PMW-8, C-1 SSK-8 and C-1 PWK-7) while soil used for this experiment was collected from Prang Ghar mining site and cabbage were grown in three levels of chromite mining soil (2.27, 4.65 and 7.14 %).The experimental design used during this research was randomized complete block design with two factors and was replicated thrice. The collected data related to the effect of chromite mining soil and Bacillus pumilus strains indicated that these both factors have significant influence on growth parameters.
