Enzymatic activity of nitrogen-fixing bacteria isolated from armenian saline soils

Abstract

Nitrogen-fixing bacteria with phytostimulating potential have great interest in the modern world. The aim of this work was to study the enzymatic activity of nitrogen-fixing strains Agrobacterium sp. M-1 and Agrobacterium sp. Y-2. Studies have shown that these strains are capable to produce proteases, lipases, cellulases, amylases and ureases, enzymes that play a vital role in maintaining soil health. In addition, these bacteria have several significant characteristics: salt tolerance, pH stability, maintaining of viability at low and high temperatures. Therefore, the above strains have every chance to become the basis for the creation of a multifunctional biofertilizer in the future.
