Special Issue Information

Dear Colleagues,

Soil is a nonrenewable finite resource and its loss or degradation is not recoverable in an easy and timely manner. Chemical contamination of soils is an issue of great concern worldwide, as it causes adverse effects to human health and wildlife ecosystems, as well as a consistent loss of land productivity. Soil contaminants include natural (e.g., petroleum-derived products, metals) and man-made chemicals (pesticides, explosives, solvents, halogenated compounds, pharmaceuticals, etc.) reaching soil by either accidental or deliberate spills, or simply through wet and dry deposition. Among the possible strategies to clean up polluted soils, bioremediation takes advantage of the catabolic versatility of (micro)organisms to either degrade contaminants or to transform them into nontoxic products, thus preserving soil functionality.

Bioremediation has been studied and steadily applied in the past decades by academic researchers and practitioners. However, more efforts are needed to understand the complex network of interactions existing between biological entities, for example, (micro)organisms, contaminants present in a polluted soil, and the soil matrix itself. The present Special Issue aims to collect original articles focusing on the variables involved in bioremediation processes: (1) Quantitative and qualitative determination of contaminants, considering also their aging and bioavailability; (2) environmental parameters and soil biodiversity/functionality; (3) effect of bioremediation intervention (e.g., biostimulation, bioaugmentation) on resident microbial communities; (4) ecotoxicology assessment.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Environments is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The biostimulation potentials of carrot peel waste and carob kibbles for bioremediation of crude petroleum-oil polluted soil were investigated. Temperature, pH, moisture, total petroleum hydrocarbon (TPH), and changes in microbial counts during 45 days were monitored when 4 mL of carrot peel waste or carob kibbles media were added to 200 g of crude oil polluted soil samples. Gas chromatography-flame ionization detection (GC-FID) was used to compare hydrocarbon present in the crude oil polluted soil and in pure fuel, composition of crude oil polluted soil was analyzed by X-ray diffraction (XRD), and the TPH was measured by distillation using distiller mud. The results showed that, at the end of experiments, the concentration of TPH decreased in crude oil polluted soil containing carrot peel waste with a percentage of 27 ± 1.90% followed by crude oil polluted soil containing carob kibbles (34 ± 1.80%) and in the unamended control soil (36 ± 1.27%), respectively. The log [Colony Forming Unit (CFU)/g] of total heterotrophic bacteria in the crude oil polluted soil increased from 10.46 ± 0.91 to 13.26 ± 0.84 for carrot peel waste, from 11.01 ± 0.56 to 11.99 ± 0.77 for carob kibbles and from 8.18 ± 0.39 to 8.84 ± 0.84 for control, respectively. Such results demonstrated that carrot peel could be used to enhance activities of the microbial hydrocarbon-degrading bacteria during bioremediation of crude petroleum-oil polluted soil. Full article
