Total no. of 1X tolerant isolates pooled down Total no of isolates highly tolerant to the given group of toxicants among the 1X tolerant isolates Total no. of isolates tolerant to all toxicants viz. heavy metals, pesticides and phenolics at 4X concentration
100 Heavy metals* 6 2
Pesticides* 3
Phenolics* 2
*Mixture of 4X toxicants belonging to the same group was taken at this level of screening (Table 1)
