Cultivation of bacteria from Aplysina aerophoba: effects of oxygen and nutrient gradients

Dataset

Description

To cultivate bacteria derived from the marine sponge Aplysina aerophoba, nine novel media formulations were created based on the predicted genomic potential of the prevalent sponge symbiont lineage Poribacteria. In an attempt to maintain microbial metabolic interactions in vitro, a Liquid-Solid cultivation approach and a Winogradsky-column approach were applied. The vast majority of microorganisms appear viable after cryopreservation as determined by selective propidium monoazide DNA modification of membrane-compromised cells, however, only 2% of the initial microbial diversity could be recovered through cultivation. In total, 256 OTUs encompassing seven microbial phyla were cultivated. The diversity of the cultivated community was influenced by the addition of the antibiotic aeroplysinin-1 as well as by medium dilution, rather than carbon source. Furthermore, the Winogradsky-column approach reproducibly enriched distinct communities at different column depths, amongst which were numerous Clostridia and OTUs that could not be assigned to a known phylum. While some bacterial taxa such as Pseudovibrio and Ruegeria were recovered from nearly all applied cultivation conditions, others such as Bacteroidetes were specific to certain medium types.
