“…24). Many researchers have employed cell separation techniques for this purpose (27,28,99,103,120,314,315,332,416,417). A major breakthrough in this area came with the realization that chemically fixed sponge and microbial cells retain their natural products in a form amenable to chemical analyses, such as high-performance liquid chromatography and nuclear magnetic resonance spectroscopy (416).…”

“…Density gradient centrifugation provides yet another opportunity for separating sponge and microbial cells. In this case, dissociated sponge tissue is placed above a density gradient (consisting of, e.g., Ficoll or Percoll), and following centrifugation, various cell fractions are formed based on differing densities (103,120,121,315). Individual fractions can then be examined chemically and microscopically to correlate the occurrence of compounds with specific cell types.…”

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.

“…Sementara itu spons dari famili Agelasidae diketahui dapat menghasilkan metabolit sekunder yang bersifat antibakteri dan antifungi, namun aktivitasnya dipengaruhi oleh kondisi lingkungan hidupnya (Orhan et al, 2012). Richelle-Maurer et al (2003) juga menemukan bahwa spons jenis Agelas conifera dari perairan Karibia dapat menghasilkan metabolit sekunder yang dapat bersifat toksik terhadap polip karang dan senyawa sceptrin yang dapat menghalau predasi ikan generalist. Sementara penelitian yang dilakukan oleh Betancourt-Lozano et al (1998) Lozano et al, 1998).…”

A seagrass ecosystem has high productivity that supports many species of associated invertebrates, including sponges. However, seagrass beds with different habitat condition, including seagrass species composition and architectural morphotypes could affect the associative sponge in the ecosystem. This study is aimed to find out about sponge species composition in different seagrass beds. The observation was conducted in two seagrass ecosystems at the east (site 1) and at the southeast (site 2) of Pramuka Island, Kepulauan Seribu, near Jakarta Bay, Indonesia. The Belt Transect was used to assess the density of sponges on the seagrass ecosystem, which was placed parallel to the coastline. The sponges species has higher number at the east than the southeast, with both sites was dominated by Spirastrella sp. and Agelas conifera. Correspondence Analysis (CA) results showed that sponges community has close interaction with seagrass abundance especially Cymodocea rotundata and Enhalus acoroides and architectural characteristic (patchily or continues meadows). Antibacterial assay of sponges tissue showed that only 7 sponge species has activity against targeting bacteria. The CA results also showed that sponge antibacterial activity was not correlated with seagrass species, with low bactericide and bacteriastatic activities. The implication of this result showed that sponges community can grow up at seagrass ecosystem eventhough their potential secondary metabolite activities is very low probably due to lack of stimulus mechanisms in the environment.

“…Today, the interest is sparked not only by the wide structural diversity, ranging from simple molecules like oroidin 8,9 to complex structures like palau'amine 10,11 and stylissadine A and B, 12 but also by their organic synthesis, 13 bio-synthesis, 14 and pharmacological activities. 6,7,15 Furthermore, these compounds have a chemo-ecological interest due to their role in chemically mediated interactions such as in the chemical defense against predators 16,17 and fouling organisms. [18][19][20] The crude extracts of different Axinella species have also been reported to inhibit the growth of several environmental bacteria.…”
