ENDOPHYTIC PROPERTIES OF STRAINS OF MICROORGANISMS MICROBACTERIUM OXYDANS ZB11 AND PAENIGLUTAMICIBACTER SULFUREUS ZB48 ON FAGOPYRUM ESCULENTUM

Abstract

Soil pollution as a result of intensive exploitation by mining companies creates a serious problem for animal health, obtaining environmentally friendly products. Among the metals that are classified as heavy, there are elements that adversely affect the body of humans and animals, inhibiting enzymatic activity, and having cumulation properties, up to toxic indicators, resulting in large-scale functional disorders. Livestock products contaminated with heavy metals also cause pathologies in humans, leading to respiratory, nervous, oncological and other diseases. Soil remediation costs are very expensive. Recently, bioremediation and phytoremediation have become innovative, cost-effective and safe methods of soil recovery from heavy metals. A combination of these methods has been adopted as a synergistic tool for soil restoration. The priority is the search for effective bacteria that promote plant growth, which serve as a biofertilizer, a bioremediation microbe, and also have endophytic properties. This helps metal-absorbing bacteria enter the plant and these plants can be easily uprooted to remove most heavy metal contaminants. The endophytic properties of microbes are selective depending on the host plant. To study the endophytic properties, we used the microorganisms Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48. Fagopyrum esculentum was treated with strains of microorganisms Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48, which exhibit endophytic properties on LB medium. The strain Microbacterium oxydans ZB11 showed endophytic activity on the root and stem. Paeniglutamicibacter sulfureus ZB48 showed endophytic activity on roots and stems 4 cm above the basal stem, showing good endophytic activity compared to Microbacterium oxydans ZB11. We report the endophytic properties of Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48 on buckwheat (Fagopyrum esculentum). Fagopyrum esculentum is known as a good plant for phytoremediation.
