HERNANDEZ-RUIZ, Gina María; ALVAREZ-OROZCO, Natalia Andrea  e  RIOS-OSORIO, Leonardo Alberto. Bioremediation of organophosphates by fungi and bacteria in agricultural soils. A systematic review. Corpoica cienc. tecnol. agropecu. [online]. 2017, vol.18, n.1, pp.138-159. ISSN 0122-8706.  https://doi.org/10.21930/rcta.vol18_num1_art:564.

Organophosphates are a type of pesticides widely used in agriculture for pest control. Since these are highly toxic compounds, their excessive use has caused great deterioration of arable soils, as well as serious damage to ecosystems and human health. Bioremediation is used as an alternative way to transform pesticides into simple, less polluting compounds, using the metabolic potential of microorganisms. Therefore, the objective of this study was to summarize the fungi and bacteria involved in bioremediation of the main organophosphorus pesticides used in agricultural soils through a systematic review of the scientific literature, in order to provide useful information for conducting further studies. Scientific information was obtained through the use of databases such as ScienceDirect and Springer Link and unindexed information was also gathered from Google Scholar, as a result of this study, it was found that the most studied organophosphate pesticide is chlorpyrifos (Toxicity category III) and microorganisms most commonly used in the bioremediation of organophosphate pesticides belongs to the genera Serratia, Bacillus and Pseudomonas. It is concluded that the success of bioremediation is influenced by the competitive ability of microorganisms, bioavailability and concentration of the organophosphate pesticide in the soil, pH, temperature and soil type, presence of nutritional supplements and high inoculum concentration.
