“…Atrazine is an s-triazine-derived herbicide that has different uses, such as agricultural applications in corn, sorghum, and sugarcane and non-agricultural applications in forestry and conifers [360]. Atrazine inhibits one subunit of the photosystem II in plants, halting this process and ultimately causing plant death.…”

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.

“…Hence, to achieve successful bioremediation of herbicide contamination, it necessitates the construction of a unique niche for the desired microbes, so they can be productively exploited [11]. Biostimulation plays a role here, by the facile addition of substrates or nutrients to the microbial habitat strictly on a "need only" basis consequently invigorating the biodegradation of target herbicide compound [12]. The aim of the present study is to evaluate the potential and optimum condition for microbial degradation of herbicide contaminated soil obtained from different farm locations around Nasarawa State University, Keffi, Nasarawa State, Nigeria…”

The presence of herbicides in soil is a serious problem for the environment. Studies on degradation of Herbicide (Paraquate dichloride (PD), Rake out (RO) and Gobara (GB)) by bacteria and fungi species isolated from soil environment in Keffi Metropolis Nigeria were carried out. A total of twenty (20) soil samples were collected. The bacteria and fungi were isolated from the soil and identified using standard microbiological methods. The herbicides utilization was determined using Atomic Adsorption Spectrometer. The effect of temperature on utilization of the herbicides by Enterobacter asburiae at 26OC ranges from 1.23±0.11 mg/ml for PD, 1.14±0.29 mg/ml for RO and 0.53±0.86mg/ml for GB, Pseudomonas aeruginosa utilization ranges from 1.45±0.17 mg/ml for PD, 1.17±0.35 mg/ml, for RO 1.12± 0.82mg/ml for GB. Aspergillus flavus ranges from 2.12±0.19 mg/ml for PD, 2.00±0.03 mg/ml for RO and 2.02±0.57 mg/ml for GB, Fusarium redolens were 2.19±0.26 mg/ml for PD, 2.15±0.08 mg/ml for RO and 1.92±0.16 mg/ml for GB. Effect of incubation time on microbial herbicides degradations: for E. asburiae on PD it ranges from day 1 with 0.24±0.37 mg/ml to day 20 with 2.06±0.11 mg/ml. for P. aeruginosa on PD ranges from day 1 with 0.38±0.08 mg/ml to day 20 with 2.39±1.45 mg/ml. The Utilization of herbicides by A. flavus on PD ranges from day 1 with 0.10±0.01 mg/ml to day 20 with 2.29±0.12 mg/ml. for F. redolens in PD, it ranges from day 1 with 0.27±0.08 mg/ml to day 20 with 2.57±0.27mg/ml. The process of degradation of herbicide has become very attractive as it allows for removal of herbicide over a relatively broad range of pH and temperature
