Abstract Marine sponges are vital components of benthic and coral reef ecosystems, providing
shelter and nutrition for many organisms. In addition, sponges act as an essential carbon
and nutrient link between the pelagic and benthic environment by filtering large quantities
of seawater. Many sponge species harbor a diverse microbial community (including
Archaea, Bacteria and Eukaryotes), which can constitute up to 50% of the sponge
biomass. Sponges of the genus Cinachyrella are common in Caribbean and Floridian
reefs and their archaeal and bacterial microbiomes were explored here using 16S rRNA
gene tag pyrosequencing. Cinachyrella specimens and seawater samples were collected
from the same South Florida reef at two different times of year. In total, 639 OTUs
(12 archaeal and 627 bacterial) belonging to 2 archaeal and 21 bacterial phyla were
detected in the sponges. Based on their microbiomes, the six sponge samples formed
two distinct groups, namely sponge group 1 (SG1) with lower diversity (Shannon-Wiener
index: 3.73 ± 0.22) and SG2 with higher diversity (Shannon-Wiener index: 5.95 ± 0.25). Hosts’ 28S rRNA gene sequences further confirmed that the sponge specimens
were composed of two taxa closely related to Cinachyrella kuekenthalli. Both sponge
groups were dominated by Proteobacteria, but Alphaproteobacteria were significantly
more abundant in SG1. SG2 harbored many bacterial phyla (>1% of sequences) present
in low abundance or below detection limits (<0.07%) in SG1 including: Acidobacteria,
Chloroflexi, Gemmatimonadetes, Nitrospirae, PAUC34f, Poribacteria, and Verrucomicrobia.
Furthermore, SG1 and SG2 only had 95 OTUs in common, representing 30.5 and 22.4%
of SG1 and SG2’s total OTUs, respectively. These results suggest that the sponge host
may exert a pivotal influence on the nature and structure of the microbial community and
may only be marginally affected by external environment parameters.
