Growth Response
The growth responses of KUMAs1 under As(III) or As(V) stress conditions both in
NB and MB are presented in Fig. 3a, b . Due to reduced growth rate of KUMAs1 at
higher level of As, in this experiment 2 mM concentration was used, which is much
higher than that found in the rhizosphere soil. In NB medium after 2 h the strain
showed steady state of growth but in MB log phase was achieved after 4 h of incuba-
tion both in presence and absence of As. KUMAs1 comparably grew well in
