An innovative approach that couples electrokinetics with microbial degradation to breakdown cycloparaffinic hydrocarbons in soils is described. Soils were spiked with cyclododecane, used as a model pollutant, at approximately 1000 mg kg−1. A mixture of petroleum-utilizing bacteria was added to achieve about 106–107 CFU g−1. Then, three treatments w...

This study demonstrated the highly efficient degradation of n-hexadecane in soil, realized by alternating bioremediation and electrokinetic technologies. Using an alternating technology instead of simultaneous application prevented competition between the processes that would lower their efficiency. For the consumption of the soil dissolved organic...

Polycyclic aromatic hydrocarbon (PAH)-degrading bacteria capable of growing under electrokinetic conditions were isolated using an adjusted acclimation and enrichment procedure based on soil contaminated with heavy PAHs in the presence of an electric field. Their ability to degrade heavy PAHs under an electric field was individually investigated in...

The present study investigated the contributions of electrokinetics (EK) and bioremediation (BIO) in the treatment of different petroleum components by using bio-electrokinetics (BIO-EK) technology with a 2-dimensional (2-D) electric field. The spatiotemporal changes of the contents of total petroleum hydrocarbons (TPH) and its components, as well...

The present study evaluated the coupling interactions between bioremediation (BIO) and electrokinetics (EK) in the remediation of total petroleum hydrocarbons (TPH) by using bio-electrokinetics (BIO-EK) with a rotatory 2-D electric field. The results demonstrated an obvious positive correlation between the degradation extents of TPH and electric in...

A new four-step approach, which removed fractions one by one based on the sequential extraction procedure proposed by the Community Bureau of Reference (BCR), was designed to study the variation of chromium (Cr) chemical fractionation after citric acid/sodium citrate (CA/SC) washing. Particular attention was paid to the potential redistribution of...

... The negative value indicates that the receptor and ligand can effectively bind and produce corresponding effects, and the smaller the ∆G of PAEs and degrading enzymes, the stronger the degradation of PAEs by the enzymes. Studies have found that the applied electric field can promote cycloalkane degradation [46]. Tiehm et al. [47] reported that the applied electric field can stimulate the ability of noncharged compounds to degrade pollutants. ...
... Using the HXD model to test traditional bioremediation has yielded some successful results using different microorganisms, such as Pseudomonas aeruginosa (Cruz et al., 2021). Additionally, Yuan et al. (2013) achieved an HXD biodegradation of 53.7% using a bacterial consortium with a constant voltage gradient of 1.3 V cm -1 for 42 days in pristine soil; and Wang et al. (2016) used alternative bioremediation and electrokinetic technologies with soil bacteria to obtain 78.5% HXD degradation after 45 days of treatment. While it is true BER has been successful in some laboratory-scale experiments, several parameters need to be explored further to create a coherent set of recommendations for successful BER use in the field. ...
... Orninthinimicrobium sp. has been isolated from active sludge [31]; however, as far as we know, this is the first report describing the presence of Orninthinimicrobium sp. in TPH-contaminated soil and the potentiality for their transformation. On the other hand, Dietzia [30] and Kocuria [32] sps. have been described as efficient in the degradation of petroleum derivatives, and Citrococcus and Gordonia sp. as involved in TPH depletion in soils [26]. ...
... Numerous studies have shown that low-molecular-weight organic acids could remove heavy metal ions in contaminated soil via chelation reactions. At the same time, they have good biodegradability and are a relatively green and mild eluting agent [24,25]. Árpád's [26] research shows that AA can effectively leach lead, and the leaching efficiency is related to the concentration. ...
... It has been shown that the application of a current modifies the metabolic responses in microorganisms, causing acceleration of biodegradation (Sarankumar et al., 2020). Furthermore, when used for petroleum-contaminated soil, BER increases bioavailability of petroleum-derived pollutants, thus making it less recalcitrant to microbial degradation (Fan et al., 2017). ...
... Acid strength is much larger and stronger and almost affects the entire reactor. This condition also shows high cation exchange capacity and low soil particle buffer capacity (Guo et al., 2014). Reactors with electrochemical processes have more microorganisms until the third day but decline rapidly on the fifth and seventh days. ...
