Genomic insights into the marine sponge microbiome
Nature Reviews Microbiology, 2012Marine sponges (phylum Porifera) often contain dense and diverse microbial communities, which can constitute up to 35% of the sponge biomass. The genome of one sponge, Amphimedon queenslandica, was recently sequenced, and this has provided new insights into the origins of animal evolution.

There is increasing interest in biotechnological production of marine sponge biomass owing to the discovery of many commercially important secondary metabolites in this group of animals. In this article, different approaches to producing sponge biomass are reviewed, and several factors that possibly influence culture success are evaluated.

Sediment impacts on marine sponges
Marine Pollution Bulletin, 2015Changes in sediment input to marine systems can influence benthic environments in many ways. Sponges are important components of benthic ecosystems world-wide and as sessile suspension feeders are likely to be impacted by changes in sediment levels. Despite this, little is known about how sponges respond to changes in settled and suspended sediment ...

Haemagglutinins from Marine Sponges
Vox Sanguinis, 1968Summary. Two species of marine sponge, Cliona celata and Axinella sp. produce haemagglutinins and a third species, Tethya aurantium produces a haemolysin. A crude Axinella sp. preparation agglutinates goose erythrocytes at 0.5 μg/ml. The two haemagglutinins differ from each other in their relative activities against erythrocytes from a range of ...

Metabolites of the marine sponge
Tetrahedron Letters, 1980Abstract The major constituent of Plakortis zygompha was (Z)-7-methyl-4-octen-3-one 1 , a highly volatile, sweet-smelling oil. The sponge also contained several derivatives of 3-hydroxy-4-hydroxymethyl-4-pentenoic acid.

Sponges are the most primitive of multicellular animals, and are major pharmaceutical sources of marine secondary metabolites. A wide variety of new compounds have been isolated from sponges. In order to produce sufficient amounts of the compounds of the needed, it is necessary to obtain large amount of sponges.

Abstract The 42 identified carotenoids isolated from 36 different marine spontes may, from structural considerations, be divided into four groups; (a) native phytoplankton-type carotenoids; (b) intact carotenoids of possible zooplankton origin, 9c) intact carotenoids of probable bacterial of fungal origin; and (d) sponge metabolized carotenoids ...

Novel actinobacteria from marine sponges
Antonie van Leeuwenhoek, 2005Actinobacteria exclusively within the sub-class Acidimicrobidae were shown by 16S rDNA community analysis to be major components of the bacterial community associated with two sponge species in the genus Xestospongia. Four groups of Actinobacteria were identified in Xestospongia spp., with three of these four groups being found in both Xestospongia ...

The sponge is one of the oldest multicellular invertebrates in the world. Because of its special pore canal structure and characteristics of filter feeding, a large amount of microorganisms adhere to it. After hundreds of thousands of years’ evolution, they form a kind of symbiosis relationship.
