Theonella swinhoei is an arsenic hyper-accumulator sponge, harboring a multitude of associated bacteria. These bacteria reside in the mesohyl, the dense extracellular matrix of the sponge. Previous elemental analysis of separated cell fractions from the sponge had determined that arsenic is localized to the associated bacteria. Subsequently, spongeassociated arsenic-tolerant bacteria were isolated here and grouped into 15 operational taxonomic units (OTUs, 97 % similarity). Both culture… 
High Proportions of Radiation-Resistant Strains in Culturable Bacteria from the Taklimakan Desert
The results of this study revealed the distribution of culturable bacteria in the Taklimakan Desert and indicated high proportions of radiation-resistant strains in theculturable bacteria, to better understand the ecological origin of radio-resistance.
Triggering Growth via Growth Initiation Factors in Nature: A Putative Mechanism for in situ Cultivation of Previously Uncultivated Microorganisms
Results indicate that the sponge Extract contains chemical compounds that facilitate recovery of non-growing microbes, and these substances worked on the in situ strains, and growth initiation factor in the sponge extract did not continuously promote growth activity but worked as triggers for regrowth (resuscitation from non- growing state).
Impact of growth media and pressure on the diversity and antimicrobial activity of isolates from two species of hexactinellid sponge
This study implemented a combination of different growth media, increased pressure and high-throughput techniques to optimize recovery of isolates from two deep-sea hexactinellid sponges, Pheronema carpenteri and Hertwigia sp.


Culturable associated-bacteria of the sponge Theonella swinhoei show tolerance to high arsenic concentrations
Results may provide an explanation for the ability of the sponge to accumulate considerable amounts of arsenic, and arsenic-mineralizing bacteria can potentially be used for the study of bioremediation, as arsenic toxicity affects millions of people worldwide.
Multiple Approaches To Enhance the Cultivability of Bacteria Associated with the Marine Sponge Haliclona (gellius) sp
ABSTRACT Three methods were examined to cultivate bacteria associated with the marine sponge Haliclona (gellius) sp.: agar plate cultures, liquid cultures, and floating filter cultures. A variety of
An Anaerobic World in Sponges
Results show the presence of an anoxic micro-ecosystem in the sponge G. barretti, and imply mutualistic interactions between sponge cells and anaerobic microbes, which may help answer unsolved questions in sponge ecology and biotechnology.
Sponge-Associated Microorganisms: Evolution, Ecology, and Biotechnological Potential
The ecology of sponge-microbe associations is examined, including the establishment and maintenance of these sometimes intimate partnerships, the varied nature of the interactions (ranging from mutualism to host-pathogen relationships), and the broad-scale patterns of symbiont distribution.
Endobionts of the Coral Reef Sponge Theonella swinhoei (Porifera, Demospongiae)
Endobionts associated with the coral reef sponge Theonella swinhoei (Lithistida, Demospongiae), from the Red Sea and Indian Ocean, were characterized through histological and ultrastructural
Single-cell genomics reveals the lifestyle of Poribacteria, a candidate phylum symbiotically associated with marine sponges
A single-cell genomics approach for the functional characterization of the candidate phylum Poribacteria implies that certain fossil biomarkers used to date the origins of metazoan life on earth may possibly be of poribacterial origin.
Cultivation of sponges, sponge cells and symbionts: achievements and future prospects.

Close related genes isolated from the highly complex metagenome of the marine sponge Theonella swinhoei, which is the source of the onnamides and theopederins, a group of polyketides that structurally resemble pederin are reported.
Single-cell genomics reveals complex carbohydrate degradation patterns in poribacterial symbionts of marine sponges
It is proposed that Poribacteria are well adapted to an existence in the sponge extracellular matrix and may be viewed as efficient scavengers and recyclers of a particular suite of carbon compounds that are unique to sponges as microbial ecosystems.
