Abstract: The factors such as global warming, wild irrigation, and synthetic fertilisers pollute the soil and increase salinity. The salinity is defined as salt stress for plants, and plants have developed various tolerance mechanisms to survive under salt stress conditions. Therefore, efforts to increase the tolerance of salt sensitive plants such as beans (Phaseolus vulgaris) are considered important. Additionally, considering problems that appear depending on global warming, understanding the tolerance mechanisms, and activating them by using natural and sustainable solutions are important for plant growth and preventing lower agricultural productivity. In this study, the effect of biofertiliser obtained from a small-scale bioreactor on a plant exposed to salt stress on the development of morphological, physiological, and biochemical properties of the model plant, Phaseolus vulgaris L. var. ellipticus Mart (Pve) were investigated. The biofertiliser application increased the amount of chlorophyll, flavonoids, anthocyanin, and proline while the amount of hydrogen peroxide and lipid peroxidation decreased in the plant. This change enhanced the enzyme activities of catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) and the plant formed tolerance to the salt stress. As a result, the biofertiliser application to the plant may activate the tolerance mechanism against salt stress.
