“…Remarkably, Usher and coworkers were also able to demonstrate the presence of cyanobacteria in sperm cells, indicating that both parents are capable of transferring symbionts to offspring (424). Sponges of the genus Chondrilla were also the subject of another recent TEM study (which additionally employed immunocytochemical techniques), in which vertical transmission of an endosymbiotic yeast was shown (221). The drawback of the TEM approach is that, with some exceptions (e.g., cyanobacteria [423,424]), even phylum-level identification of the relevant microorganisms is not possible due to an insufficient number of distinguishing morphological characters.…”

“…It thus remains unclear in most cases whether such fungi are consistently associated with the source sponge, or even whether they are obligate marine species. Compelling evidence for symbiosis of a yeast with sponges of the genus Chondrilla was obtained by extensive microscopy studies of both adult sponge tissue and reproductive structures, with strong indications of vertical transmission of the yeast symbiont (221).…”

SUMMARY Marine sponges often contain diverse and abundant microbial communities, including bacteria, archaea, microalgae, and fungi. In some cases, these microbial associates comprise as much as 40% of the sponge volume and can contribute significantly to host metabolism (e.g., via photosynthesis or nitrogen fixation). We review in detail the diversity of microbes associated with sponges, including extensive 16S rRNA-based phylogenetic analyses which support the previously suggested existence of a sponge-specific microbiota. These analyses provide a suitable vantage point from which to consider the potential evolutionary and ecological ramifications of these widespread, sponge-specific microorganisms. Subsequently, we examine the ecology of sponge-microbe associations, 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. The ecological and evolutionary importance of sponge-microbe associations is mirrored by their enormous biotechnological potential: marine sponges are among the animal kingdom's most prolific producers of bioactive metabolites, and in at least some cases, the compounds are of microbial rather than sponge origin. We review the status of this important field, outlining the various approaches (e.g., cultivation, cell separation, and metagenomics) which have been employed to access the chemical wealth of sponge-microbe associations.

“…Yeasts (e.g. Maldonado et al, 2005), and viruses (e.g. Lohr et al, 2005) have also been reported to live within sponges but whether these micro-organisms are parasites or symbionts has not been elucidated yet.…”

Vertical transmission and successive location of symbiotic bacteria during embryo development and larva formation in Corticium candelabrum (Porifera: Demospongiae)

2007

This study reports on the transfer of heterotrophic bacteria from parental tissue to oocytes in the Mediterranean bacteriosponge Corticium candelabrum (Homosclerophorida) and the description of the successive locations of the microsymbionts during embryo development through transmission and scanning electron microscopy. Eight different types of symbiotic bacteria are described morphologically. These eight bacteria morphotypes are found in both adult individuals and larvae. Symbiotic bacteria are transferred to oocytes, but not to spermatocytes. Bacteria are first located at the oocyte periphery below a thick collagen layer and then they migrate to the oocyte cytoplasm, forming spherical clusters. After cleavage, the bacteria can be found in the free space between blastomeres but mainly accumulate at the embryo periphery below the follicular cells that surround the embryo. Once the blastocoel is formed, the symbiotic bacteria move to this central cavity where they actively divide by bipartition, increasing their number considerably. Many examples of phagocytosed bacteria in the proximal zone of the larval cells are observed at this stage. Consequently, bacteria may represent a complementary source of energy for free larvae and settlers before they are able to capture food from the surrounding water.

“…They have attracted substantial research interest because of their ecological importance and their production of a wide range of bioactive compounds for pharmacological use (Vogel, 2008). One striking characteristic of sponges is their association with a remarkable array of microorganisms, including archaea (Preston et al, 1996), bacteria , cyanobacteria (Thacker and Starnes, 2003), unicellular algae (Vacelet, 1982), dinoflagellates (Garson et al, 1998) and fungi (Maldonado et al, 2005), which can constitute up to 60% of the tissue volume in some sponge species (Vacelet and Donadey, 1977;Hentschel et al, 2003) and exceed a density of 10 9 microbial cells per ml of sponge tissue ). The extraordinary highly abundant and diverse microorganisms in sponges have led to ecological questions on their role, consistency and specificity of their association, and it is still enigmatic how the association is established and maintained.…”

Pyrosequencing reveals highly diverse and species-specific microbial communities in sponges from the Red Sea

et al. 2010

Marine sponges are associated with a remarkable array of microorganisms. Using a tag pyrosequencing technology, this study was the first to investigate in depth the microbial communities associated with three Red Sea sponges, Hyrtios erectus, Stylissa carteri and Xestospongia testudinaria. We revealed highly diverse sponge-associated bacterial communities with up to 1000 microbial operational taxonomic units (OTUs) and richness estimates of up to 2000 species. Altogether, 26 bacterial phyla were detected from the Red Sea sponges, 11 of which were absent from the surrounding sea water and 4 were recorded in sponges for the first time. Up to 100 OTUs with richness estimates of up to 300 archaeal species were revealed from a single sponge species. This is by far the highest archaeal diversity ever recorded for sponges. A non-negligible proportion of unclassified reads was observed in sponges. Our results demonstrated that the sponge-associated microbial communities remained highly consistent in the same sponge species from different locations, although they varied at different degrees among different sponge species. A significant proportion of the tag sequences from the sponges could be assigned to one of the sponge-specific clusters previously defined. In addition, the sponge-associated microbial communities were consistently divergent from those present in the surrounding sea water. Our results suggest that the Red Sea sponges possess highly sponge-specific or even sponge-species-specific microbial communities that are resistant to environmental disturbance, and much of their microbial diversity remains to be explored.
