Aerobic SMX biodegradation patterns of pure cultures in R2A-UV media. A) measured with UV-AM, initial SMX concentration 10 mg L-1. B) LC-UV analyses of SMX concentrations within the nine pure cultures in R2A-UV media performed at experimental startup, after 4 and 10 days to verify the results of UV-AM. Asterisks indicate measured values below limit of detection. Shown are mean SMX absorbance values of duplicate experiments. Standard deviations were too low to be shown (<1%).
