4-Hydroxybenzoic acid is a common organic compound in the environment, and its persistence leads to the expulsion of pollution-related adverse effects. Two bacterial strains FZ-5 and FZ-8 capable of utilizing 4-HBA as the sole carbon and energy source under anaerobic conditions was isolated from marine sediment samples, which was identified in this study. The two strains FZ-5 and FZ-8 were identified as Acutebacter johnsonii and Klebsiella oxytoca, respectively, according to Phylogenetic study. Degraded 2000 mgl-FZ-8 degraded to 80. 1 percent and 80. 1 percent, respectively, in 72 hours, respectively, with degradation rates of 71. 04% and 80. 10%. The strains FZ-5 and FZ-8, which were inoculated soil, led to higher degradation of 4-HBA than the uninoculated soil, and the strains could survive well in anaerobic soil. The strains studied in this report demonstrated that they could degrade 4-HBA in anaerobic soil and may aid in the establishment of 4-HBA anaerobioremediation systems.
