Contribution to the study of rhizobacterial biocontrol of the vascular fusarium of the pea Pisum sativum

Abstract

This study examined the use of biological approaches to control vascular Fusarium in plants through the interaction of root and fungal diseases. One of the main forces controlling plants by biological methods is the antifungal bacteria found in rhizosphere pathogens. Twenty isolates were identified based on bacterial as well as biochemical and biophysical tests. During our biostimulation experiments, we have enzyme activity to discover how bacteria respond to substrate sources and how environmental factors affect enzymatic reactions. As part of our biostimulation experiments, we studied the activity of enzymes to understand how bacteria access various sources of substrates and the influence of conditions on these enzymatic reactions. This study was carried out on using 8 different bacteria, and led to the discovery of a catalytic enzyme in these processes. In addition, the activity of rhizobacteria promoting the growth of was studied and in this context, most bacterial isolates showed their ability to improve phosphates. We also observed the production of compounds such as hydrocyanide and Indole-3-acetic acid (IAA), as well as the production of ammonia. These results improve our understanding of the impact of bacteria on enzymatic processes and their ability to stimulate plant growth, and indicate the importance of PGPR bacteria in promoting plant health and environmental sustainability.
