Figure 1: ε-caprolactam tolerance of Bacillus cereus on 0.5-4% εcaprolactam fortified medium. Tolerance is represented on y-axis and variable concentration of ε-caprolactam fortified medium is on x-axis. Parameters monitored were % COD reduction, growth parameters like OD (at 600 nm), dry weight of cell (DWC) in g/L and colony forming units (cfu)
