What is Verification of Necessity for Bioaugmentation—lessons from Two Batch Case Studies for Bioremediation of Diesel-contaminated Soils about?
## Abstract **BACKGROUND:** Two bio‐pile studies undertaken in a controlled laboratory were aimed at deciding optimal strategies to remediate two different artificial diesel‐contaminated soils. Bioaugmentation with various inoculations, biostimulation with various levels of biosurfactant rhamnolipid, and nutrient enhancement were the proposed remediation courses. **RESULTS:** In Case I, the average of the first‐order kinetic degradation rate constants during the first degradation stage for the bioaugmentation/biostimulation treatments was 0.0195 ± 0.0056 d^−1^, which was about 2.6‐fold higher than that of the control batch (0.0075 d^−1^). Conversely, in Case II, the rate constants for treatments with amendments and those for the control batch were found to be comparable, 0.0172 ± 0.0015 d^−1^ and 0.0158 d^−1^, respectively. Microarray results indicated a less diverse indigenous bacterial community in Case I and an abundant indigenous community in Case II, both from the control batches on Day 0. The dynamics of the two microbial communities, revealed by NMS plots, emphasized the similarity among the different treatments during the first degradation stage. **CONCLUSIONS:** Prior to a
