Procedures in ready biodegradability testing: effects of the inoculation and the monitored parameter

摘要

Ready biodegradability tests are often limited because of a lack of definition in some operating conditions, which can be critical for reproducibility and efficiency. In this paper, the effects of the monitored analytical parameter and the variations in the inoculum quantity on test results are studied. In as Sturm standardized assay, sodium acetate and dodecylbenzene sulfonate (DBS) were tested at several initial substrate to biomass ratios (S_o/X_o). The analytical parameter did show itself to be determinant in the estimation of the extent of the acetate biodegradation.
