“…To eliminate soil DDT, many methods have been explored, including biodegradation (Xu et al, 2019), photochemical reactions (Quan et al, 2005), electrochemical processes (Sudharshan et al, 2012), high-temperature calcinations (Yan et al, 2014), zero-valent metals (Kang et al, 2018). Of these methods, biodegradation, especially in situ microbial degradation by indigenous microorganisms, is regarded as one of the most promising detoxifying technologies because of its low cost, environment-friendly effects and low secondary pollution (Abbes et al, 2018, Purnomo et al, 2011. However, natural biodegradation of DDT in soils has been found to be very slow (Mansouri et al, 2017).…”

“…For bioaugmentation tests in the sterile and non-sterile soil, we followed the same steps except, in the case of the sterile soil, sterilizing it by autoclaving at 120°C for 15 min [ 16 ]. In a flask, 10 g of soil was mixed with 500 mL of sterilized M9 medium, then 70 x 10 9 bacteria cells were inoculated.…”

“…Nowadays, a series of bioremediation technologies have attracted the attention of scientists because of their exceptional advantages and their high efficiency in cleansing soils contaminated by heavy metals [ 2 ]. Especially, microbial bioremediation is envisioned as a biological treatment technique for polluted soil [ 16 ], applied for the removal and/or recovery of TMEs in contaminated environments through the use of microorganisms [ 3 ]. It is an efficient, promising and environmentally friendly depollution technique [ 17 ] compared to physicochemical techniques.…”

Pollution by lead (Pb) is an environmental and health threat due to the severity of its toxicity. Microbial bioremediation is an eco-friendly technique used to remediate contaminated soils. This present study was used to evaluate the effect of two bacterial strains isolated and identified from Bizerte lagoon: Cupriavidus metallidurans LBJ (C. metallidurans LBJ) and Pseudomonas stutzeri LBR (P. stutzeri LBR) on the rate of depollution of soil contaminated with Pb from Tunisia. To determine this effect, sterile and non-sterile soil was bioaugmented by P. stutzeri LBR and C. metallidurans LBJ strains individually and in a mixture for 25 days at 30°C. Results showed that the bioaugmentation of the non-sterile soil by the mixture of P. stutzeri LBR and C. metallidurans LBJ strains gave the best rate of reduction of Pb of 71.02%, compared to a rate of 58.07% and 46.47% respectively for bioaugmentation by the bacterial strains individually. In the case of the sterile soil, results showed that the reduction rate of lead was in the order of 66.96% in the case of the mixture of the two bacterial strains compared with 55.66% and 41.86% respectively for the addition of the two strains individually. These results are confirmed by analysis of the leachate from the sterile and non-sterile soil which showed an increase in the mobility and bioavailability of Pb in soil. These promising results offer another perspective for a soil bioremediation bioprocess applying bacterial bioremediation.

“…DDD is more common in anaerobic conditions, while DDE is associated with aerobic conditions [332]. Under aerobic conditions, DDT is transformed into DDE by dehydrochlorination carried out by the dehydrochlorinase enzyme [333]. Only a few microorganisms can completely degrade DDE to CO 2 using co-metabolism of biphenyl to obtain biphenyl dioxygenase, an enzyme required to degrade DDE [334].…”

Pesticides are chemicals used in agriculture, forestry, and, to some extent, public health. As effective as they can be, due to the limited biodegradability and toxicity of some of them, they can also have negative environmental and health impacts. Pesticide biodegradation is important because it can help mitigate the negative effects of pesticides. Many types of microorganisms, including bacteria, fungi, and algae, can degrade pesticides; microorganisms are able to bioremediate pesticides using diverse metabolic pathways where enzymatic degradation plays a crucial role in achieving chemical transformation of the pesticides. The growing concern about the environmental and health impacts of pesticides is pushing the industry of these products to develop more sustainable alternatives, such as high biodegradable chemicals. The degradative properties of microorganisms could be fully exploited using the advances in genetic engineering and biotechnology, paving the way for more effective bioremediation strategies, new technologies, and novel applications. The purpose of the current review is to discuss the microorganisms that have demonstrated their capacity to degrade pesticides and those categorized by the World Health Organization as important for the impact they may have on human health. A comprehensive list of microorganisms is presented, and some metabolic pathways and enzymes for pesticide degradation and the genetics behind this process are discussed. Due to the high number of microorganisms known to be capable of degrading pesticides and the low number of metabolic pathways that are fully described for this purpose, more research must be conducted in this field, and more enzymes and genes are yet to be discovered with the possibility of finding more efficient metabolic pathways for pesticide biodegradation.
