“…Long-term manufacturing and use of xenobiotic chemicals have resulted in the gradual accumulation of persistent organic pollutants (POPs) globally [1][2][3][4][5]. Ingestion of POPs by an organism evokes bioaccumulation [6][7][8][9], which generally results in more-or-less harmful effects to numerous organisms [10][11][12], especially to the ubiquitous beetle larvae.…”

The potential use of invertebrates as bioreactors to treat environmental pollutants is promising and of great interest. Three types of the persistent organic pollutants (POPs), namely pentachlorophenol (PCP), PAHs (naphthalene and phenanthrene) and dieldrin (DLN), were spiked in soil and treated by using Oryctes rhinoceros larvae, a known pest of coconut trees in southeast Asia, and also the indicators of POP toxicity and the fate and degradability of the ingested POPs were assessed. The larvae were tested at various levels of the POPs and went through an acclimation process. Without acclimation, the tolerance limits of the larvae toward PCP, PAHs and DLN were 200, 100 and 0.1 mg/kg-soil, respectively, yet with acclimation, the tolerance levels increased to 800, 400 and 0.5 mg/kg-soil, respectively. Biodegradation rates of all the tested POPs were >90% by week 2, with <5% and nearly 0% remaining in the feces and body of the larvae, respectively. The results suggest that the use of the beetle larvae in soil POP decontamination is doable.

“…Among the remediation strategies for treating TPH-contaminated soils, combining chemical and biological processes has been shown to effective (Palmroth etal., 2006), Using abiotic processes, hydrogen peroxide has been widely used to degrade xenobiotics in slurry systems requiring large amounts of hydrogen peroxide, and the generated hydroxyl radical is strongly reactive and toxic to microorganisms (Danner et al, 1973;Umezawa and Higuchi, 1989;Palmroth et al, 2006;Oh and Shin, 2013) A wide range of pentachlorophenol (PCP), polycyclic aromatic hydrocarbons (PAHs), lipids, and fatty acids are catalytically oxidized by heme and heme proteins (Rice et al, 1983;Chen et al, 2006;Chen et al, 2009;Chung et al, 2014;Kang et al, 2015). By analogy to the peroxidase system, it was verified that adding hydrogen peroxide to soil containing heme, in which the iron is present as Fe…”

Biocatalytic degradation of total petroleum hydrocarbons (TPHs) in contaminated soil by hemoglobin and hydrogen peroxide is an effective soil remediation method. This study used a laboratory soil reactor experiment to evaluate the effectiveness of a nonspecific biocatalytic reaction with hemoglobin and H 2 O 2 for treating TPH-contaminated soil. We also quantified changes in the soil microbial community using real-time PCR analysis during the experimental treatment. The results show that the measured rate constant for the reaction with added hemoglobin was 0.051/day, about 3.5 times higher than the constant for the reaction with only H 2 O 2 (0.014/day). After four weeks of treatment, 76% of the initial soil TPH concentration was removed with hemoglobin and hydrogen peroxide treatment. The removal of initial soil TPH concentration was 26% when only hydrogen peroxide was used. The soil microbial community, based on 16S rRNA gene copy number, was higher (7.1 × 10 6 copy number/g of bacteria, and 7.4 × 10 5 copy number/g of Archaea, respectively) in the hemoglobin catalyzed treatment. Our results show that TPH treatment in contaminated soil using hemoglobin catalyzed oxidation led to the enhanced removal effectiveness and was non-toxic to the native soil microbial community in the initial soil.
