Abstract

Agriculture is critical to any economy, particularly those in developing and developing countries. Increased abiotic and biotic stressors have a negative impact on crop output around the world. Microorganisms that live in the Rhizospheric zone of plant soil are known to help alleviate these pressures, resulting in increased crop productivity and output. The goal of this study was to study the antibacterial and antifungal activity of Rhizospheric bacteria, which is isolated from the rhizosphere soil of the Zawar mines area in Udaipur, Rajasthan, India, and the Pirana landfill site in Ahmedabad, Gujarat, India, and demonstrating the ability to withstand both abiotic (heavy metal) and biotic stress. Six of the 91 bacterial isolates that showed strong tolerance to heavy metal were chosen for further investigation. Three from the Zawar mines area and three from the paranal and fill site showed great resistance to heavy metal, and their biotic stress tolerance was explored further. Antifungal activity was tested using Macrophomina phaseolina, Fusarium oxysporium (Pink), Fusarium oxysporium (White), Aspergillus niger, and Trichoderma spp. Antibacterial activities of the three chosen bacterial strains were also evaluated against Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis, and Bacillus pumilus). SMHMZ4 and SMHMP23 have the most antagonistic activity among the six bacterial strains investigated.
