“…Reductions in the range of 38.8 -58.5% obtained for naphthalene in this study are consistent with the studies mentioned above. We know from one of our previous studies that O2 content in the reactor headspace remains above 15% for this reactor configuration (Kahraman et al 2017). So, the contribution of the anaerobic reductive degradation appears to be minimum.…”

The co-contamination of soils with heavy metals and organic contaminants is a problem that requires a different and innovative approach to remediate these kinds of sites. The different nature of these two contaminant groups makes the problem complicated. Recently, zero-valent iron nanoparticles (nZVI) application has been integrated with bioremediation to be used for the remediation of halogenated organics. However, the use of this process for the remediation of co-contaminated soils has not been investigated. In this study, nZVI application integrated with bioremediation approaches (bioattenuation and biostimulation) was applied to Pb and naphthalene spiked soils in laboratory-scale reactors. Soil Pb fractions and naphthalene concentrations were monitored for 90 days. The nZVI decreased the mobility and bioavailability of Pb significantly by reducing exchangeable and carbonate bound fractions from 66.2 % to 25.8 -37.2 % range. The nZVI also caused naphthalene degradation in the range of 38.8 -58.5 %. Significant biodegradation of naphthalene occurred at samples subjected to nZVI and biostimulation. The highest overall naphthalene degradation (76.7 %) was obtained from the nZVI application which was integrated with biostimulation.

“…Nitrogen, as an essential element of proteins, nucleic acids, and other nitrogen compounds of living organisms, plays a vital role in microbial growth and product synthesis (Kahraman et al, 2017). Ammonium nitrate (NH 4 NO 3 ) includes two forms of nitrogen, ammonium and nitric acid, which can supply two different nitrogen sources at the same time.…”

With the increasing demand for diesel in various countries, the ecological pollution caused by the improper use, storage, and accidental leakage of diesel needs to be addressed urgently. As an environmentally friendly and cost-effective method, bioremediation generally uses various microorganisms to remove pollutants from the environment. Here, the strain KJ-1, obtained through an enrichment culture using n-dodecane from oil-contaminated soil near a gas station as the substrate, was identified as Acinetobacter vivianii according to its morphology, biochemistry, and molecular biology. The isolate KJ-1 was able to use diesel as a sole carbon source and more than 40% of diesel was degraded after 12 days of incubation with strain KJ-1 in mineral salts medium. The most suitable diesel concentration and nitrogen source concentrations were 4,140 mg/L and 350–700 mg/L, respectively, for diesel degradation and bacterial growth. The optimal initial pH and temperature for strain KJ-1 growth and diesel degradation were 6.5–8.0 and 20–37°C, respectively. To investigate the diesel-degrading mechanisms of this strain, the complete genome was sequenced and annotated. The complete genome consists of one chromosome with a total length of 3,927,757 base pairs and a G + C content of 41.5%. The genes related to the two-component regulatory system and alkane degradation were analyzed. In addition, two putative alkane monooxygenases were analyzed, and the protein sequences were characterized and compared with other AlkBs in Acinetobacter spp. using sequences downloaded from NCBI. The results demonstrated that A. vivianii KJ-1 may be particularly useful for future bioremediation of diesel-polluted soil.
