In this research, the rhizosphere soil microbiome diversity of mangrove trees such as Avicennia marina, Ceriops tagal Proteobacteria, Actinobacteria, Firmicutes, Fibrobacterota, Chlorobiota, and Bacteroidota were found to be predominant phyla present in all samples; Unculturable environmental microbes were also detected, particularly abundant in S. maritima and S. monoica samples. Staphylococcus aureus, Vibrio parahaemolyticus, Klebsiella pneumoniae, Salmonella enterica, Streptomyces griseocarneus were the most abundant species observed in this study. The variations in bacterial community structure across these ecosystems may be influenced by the distinct environmental conditions of each sampled mangrove habitat. For the first time, our findings highlight the richness of microbial diversity in the Karankadu mangroves, providing essential baseline data and revealing differences between mangrove trees and halophytes. This study offers valuable insights for further investigation into the mechanisms governing rhizosphere microbiome interactions with their host environment.
