El género y especie Rhizobium phaseoli es usado como inoculante en la producción de Phaseolus vulgaris (fríjol), porque en los nódulos de sus raíces, establece una simbiosis para fijar el nitrógeno molecular (FBN) y suplir la demanda de nitrógeno (N) para un crecimiento sano. En el cultivo de P. vulgaris se aplican plaguicidas en el control de insectos plaga de raíz, que evitan el efecto benéfico de R. phaseoli., por lo que los objetivos de este trabajo fueron aislar y seleccionar R. phaseoli tolerante a diazinón. Para ello, R. phaseoli se creció en caldo extracto levadura manitol con diazinón y selecciono R. phaseoli tolerante al insecticida e inoculó en P. vulgaris para determinar la infectividad con base en el número de nódulos, mientras que la efectividad para la FBN en la raíz, de acuerdo al incremento en el peso fresco y seco, en la altura de la planta, y en la capacidad para degradar el diazinón. Se concluye que el R. phaseoli tolerante a diazinón fue infectivo y efectivo para el sano crecimiento de P. vulgaris.

“…Therefore, their effect on OPCs can be nonspecific, and their activity can be greatly reduced in comparison with other substrates or even inhibited by OPC alone [ 69 ] or in combination with other substances [ 70 ]. Nevertheless, compounds of a wide subclass of OPCs containing P=S bond (e.g., parathion [ 71 ], phosmet [ 72 ], diazinon [ 73 ], etc.) are designed specifically for biochemical activation due to cytochromes.…”

Organophosphorus compounds (OPCs) are able to interact with various biological targets in living organisms, including enzymes. The binding of OPCs to enzymes does not always lead to negative consequences for the body itself, since there are a lot of natural biocatalysts that can catalyze the chemical transformations of the OPCs via hydrolysis or oxidation/reduction and thereby provide their detoxification. Some of these enzymes, their structural differences and identity, mechanisms, and specificity of catalytic action are discussed in this work, including results of computational modeling. Phylogenetic analysis of these diverse enzymes was specially realized for this review to emphasize a great area for future development(s) and applications.

Diazinon is an organophosphorus pesticide widely used to control cabbage insects, cotton aphids and underground pests. The continuous application of diazinon in agricultural activities has caused both ecological risk and biological hazards in the environment. Diazinon can be degraded via physical and chemical methods such as photocatalysis, adsorption and advanced oxidation. The microbial degradation of diazinon is found to be more effective than physicochemical methods for its complete clean-up from contaminated soil and water environments. The microbial strains belonging to Ochrobactrum sp., Stenotrophomonas sp., Lactobacillus brevis, Serratia marcescens, Aspergillus niger, Rhodotorula glutinis, and Rhodotorula rubra were found to be very promising for the ecofriendly removal of diazinon. The degradation pathways of diazinon and the fate of several metabolites were investigated. In addition, a variety of diazinon-degrading enzymes, such as hydrolase, acid phosphatase, laccase, cytochrome P450, and flavin monooxygenase were also discovered to play a crucial role in the biodegradation of diazinon. However, many unanswered questions still exist regarding the environmental fate and degradation mechanisms of this pesticide. The catalytic mechanisms responsible for enzymatic degradation remain unexplained, and ecotechnological techniques need to be applied to gain a comprehensive understanding of these issues. Hence, this review article provides in-depth information about the impact and toxicity of diazinon in living systems and discusses the developed ecotechnological remedial methods used for the effective biodegradation of diazinon in a contaminated environment.
