Novel pteridine alkaloids from the sponge Clathria sp.
(Pergamon-Elsevier Science Ltd, 2002-05)
Three novel pteridine alkaloids, pseudoanchynazines A-C (1-3) have been isolated from the sponge Clathria sp. collected by trawling (-100m) in a commercial clam fishery near the coasts of Rio Negro, Argentina, and their ...
Variation of antimicrobial activity of the sponge Aplysina fistularis (Pallas, 1766) and its relation to associated fauna
(Journal of Experimental Marine Biology and Ecology, 1998)
The sponge Aplysina fistularis (Pallas, 1766) was studied to determine if it produces different levels of antibiotic activity during an annual cycle, and to try to establish some ecological relations of this phenomenon. ...

(Springer, 2013)
Unlike filamentous fungi and bacteria, very
little is known about cultivable yeasts associated with
marine sponges, especially those from Antarctic seas.
During an expedition to King George Island, in the Antarctica,
samples ...
Prokaryotic, Fungal, and Unicellular Eukaryotic Core Communities Across Three Sympatric Marine Sponges From the Southwestern Atlantic Coast Are Dominated Largely by Deterministic Assemblage Processes
(2021-06-08)
Marine sponges are known to harbor a diverse and complex microbiota; however, a vast majority of surveys have been investigating the prokaryotic communities in the north hemisphere and Australia. In addition, the mechanisms ...
Estudio quimico de dos especies de esponjas marinas del sur de Chile
(1998)
Fatty acids and sterols have been isolated and identified from the Chiloé sponges lophon proximum (Ridley 1881) and lophon sp. The structures of these compounds were established by means of spectroscopic evidence and ...
Antimycobacterial brominated metabolites from two species of marine sponges
(2006)
A screening of 500 crude extracts of marine invertebrates against the growth of Mycobacterium tuberculosis H37Rv yielded MeOH extracts of the sponges Aplysina cauliformis and Pachychalina sp. with significant activity. ...
