Abstract
Marine environments, particularly coastal regions, harbor a rich and underexplored diversity of halotolerant bacteria with potential biotechnological applications. The present study aims to isolate, identify, and characterize halotolerant bacterial strains from the coastal areas of Veraval and Kodinar in Saurashtra, Gujarat, to assess their physiological traits and potential uses. This study explores the isolation, diversity, and physiological characterization of marine halotolerant bacteria from the coastal areas of Veraval and Kodinar in Saurashtra, Gujarat. A total of five soil samples were collected from distinct locations in these coastal regions, and 20 bacterial isolates were obtained. From these, 14 halotolerant strains were selected based on their ability to grow in high salt concentrations (2 – 10% NaCl). These isolates were comprehensively characterized for various physiological traits, including biofilm formation, exopolysaccharide (EPS) production, antibiotic sensitivity, antagonistic activity against pathogens, coexistence, metal resistance, hemolytic activity, enzyme production (amylase, protease, and lipase), and nitrate reduction. Additionally, the isolates were optimized for growth under varying conditions, such as pH, temperature, carbon source, nitrogen source, and salt concentration. The findings of this study highlight the remarkable diversity and potential applications of these halotolerant bacteria in sustainable agriculture, environmental management, and biotechnology. The isolates exhibited a range of beneficial traits, suggesting their potential use in promoting plant growth, mitigating soil pollution, and developing novel biofertilizers and biopesticides. This research contributes to the understanding of marine microbial diversity and its applications, providing valuable insights for future studies and potential industrial applications. The study’s results have significant implications for the development of sustainable agricultural practices and environmental management strategies. Further research on these halotolerant bacteria could lead to the discovery of novel enzymes, bioactive compounds, and other valuable products.
