Bacterial community composition and function in different habitats in Antarctic Fildes region revealed by high-throughput sequencing.

ABSTRACT:

Introduction

Pristine soil, ornithogenic soil, intertidal sediment, and marine sediment represent four of typical habitats in the Fildes region, maritime Antarctica. However, information on bacterial community composition and function in these Antarctic habitats remain limited.

Methods

In this study, using a combination of 16S rRNA gene amplicon sequencing and shotgun metagenomic sequencing, 12 samples collected from various habitats in the region were analyzed.

Results and discussion

Bacterial community compositions in terrestrial habitats (i.e., pristine and ornithogenic soils) were found to be distinct (p < 0.01) from those in marine habitats (i.e., marine and intertidal sediments). Organic carbon (p < 0.01) and pH (p < 0.01) were two major env
