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.

Biochemical Systematics and Ecology, 1982
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 ...

Antimicrobial Activity of some Marine Sponges
Nature, 1969THE evaluation of marine plants and animals for potential use in chemotherapy poses problems of procurement of materials and of techniques of screening for significant drug activity1. We have been studying antimicrobial activity in marine sponges both from the viewpoint of marine ecology and in an effort to develop new drugs, and report on our methods ...

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.

Anticancer agents from marine sponges
Journal of Asian Natural Products Research, 2014Marine sponges are currently one of the richest sources of anticancer active compounds found in the marine ecosystems. More than 5300 different known metabolites are from sponges and their associated microorganisms. To survive in the complicated marine environment, most of the sponge species have evolved chemical means to defend against predation. Such

Producing drugs from marine sponges
Biotechnology Advances, 2003Marine sponges are potential sources of many unique metabolites, including cytotoxic and anticancer compounds. Natural sponge populations are insufficient or inaccessible for producing commercial quantities of metabolites of interest. This review focuses on methods of producing sponge biomass to overcome supply limitations.

[Bioactive compounds from marine sponges and cell culture of marine sponges].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2002Presented a survey of bioactive compounds discovered from marine sponges in the recent five years, including the classes, distribution and their potential pharmaceutical uses. In particular, the compounds with antitumor, antivirus and antibacteria activity were discussed with their originating marine sponge species.

New tetrahydropyrans from a marine sponge
Tetrahedron, 1982Two new tetrahydropyrans were isolated from the sponge Haliclona sp. From chemical and spectroscopic evidence they are shown to be (1''R,2S,2''E,5R,6R)-2-(1''-bromomethyl)-2,5-dimethyl-6-(penta-2'',4''-dienyl)tetrahydropyran and (1''R,2S,5R,6R)-2-(1''-bromomethyl)-2,5-dimethyl-6-(pent-4''-enyl)-tetrahydropyran.
