Modified data. The first step was to select a subset of useful columns, and do some early data processing to have a reasonable data set.
Oct 06, 2020 · One-millilitre aliquots were removed daily to analyse the kinetics of the antibiotic degradation and ligninolytic activity. The concentration of the remaining SAs was determined by placing 1-mL aliquots of liquid broth in Eppendorf tubes and centrifuged at 5000 rpm for 1 min, and the supernatant was filtered through 0.45-μm nylon syringe filters.

A calibration curve was done with standards containing AA concentrations of 284, 852, 1419, 1987, 2555 and 3123 M. Samples were diluted (1:4) with a 1000 mg L 1 EDTA solution and filter ed through a 0.45 m syringe filter. To determine DHA, L dithiothreitol (DTT) was added at a 13 mM (0.2%) final concentration in samples in order to reduce DHA
