A first report on prokaryotic diversity in northwestern Arafura deep-sea sediments, Indonesia.

ABSTRACT: Indonesia's deep-sea microbial communities remain poorly understood, prompting the need for comprehensive investigations. This study aimed to assess the bacterial and archaeal diversities in northwestern Arafura deep-sea sediments, spanning depths of 100 to 1,457 m using a 16S rRNA based-metagenomic sequencing approach, without technical and biological replicates. Principal component analyses based on the Bray-Curtis dissimilarity index indicated that most of the bacterial and archaeal communities were habitat-specific and influenced by depth. The most prevalent known bacterial phylotypes were detected from all samples belonging to the phylum of Desulfobacteriota, Pseudomonadota, and Firmicutes. In addition, the samples also harbored diverse members of the Archaea domain, including Crenarc
