The microbial community is one of the many varied groups found in the ocean. Studies have showed that microorganisms isolated from the marine environment are metabolically active and have adapted to life in the water. To battle heavy metal stress and decolorization of diverse textile dyes, marine microorganisms employ a variety of survival strategies, and hence play an essential role in cadmium bioremediation and textile dye degradation. The current research focuses on the isolation and 16S rRNA molecular characterisation of M3, M8 bacterial strains recovered from Visakhapatnam port marine water samples. The potential of M3 and M8 isolates to remove cadmium from the environment and decolorize various textile dyes was also examined. The tube dilution method was employed to isolate bacterial strains from the water sample, and 10 distinct isolates were examined. To identify the species, biochemical tests were performed on the isolates, as well as 16S rRNA molecular sequencing and phylogenetic analysis. Bacillus subtilis and Pseudomonas resinovorans were identified as Bacillus subtilis and Pseudomonas resinovorans, respectively, after 16srRNA molecular sequencing and phylogenetic analysis. The two bacterial strains showed promising dye degradation characteristics as well as removal of cadmium from the growing media when tested with nine different textile dyes with wavelengths ranging from 400 to 600nm. The isolates M3 and M8 are shown to be potential strains for dye decolorization and cadmium bioremediation in the current investigation.
