Bioactivity of Spongian Diterpenoid Scaffolds from the Antarctic Sponge Dendrilla antarctica

open access: yesMarine Drugs, 2020
The Antarctic sponge Dendrilla antarctica is rich in defensive terpenoids with promising antimicrobial potential. Investigation of this demosponge has resulted in the generation of a small chemical library containing diterpenoid secondary metabolites ...

Environmental Flow Regimes for Dysidea avara Sponges

open access: yes, 2008
The aim of our research is to design tank systems to culture Dysidea avara for the production of avarol. Flow information was needed to design culture tanks suitable for effective production. Water flow regimes were characterized over a 1-year period for

Soest R (2006) Speculation with spiculation?–Three independent gene fragments and biochemical characters versus morphology in demosponge higher classification. Mol Phylogenet Evol 38

open access: yes, 2020
Demosponge higher-level systematics is currently a subject of major changes due to the simplicity and paucity of complex morphological characters. Still, sponge classification is primarily based on morphological features.

Isolation and Characterization of a Mn(II)-Oxidizing Bacillus Strain from the Demosponge Suberites domuncula

open access: yesMarine Drugs, 2010
In this study we demonstrate that the demosponge Suberites domuncula harbors a Mn(II)-oxidizing bacterium, a Bacillus strain, termed BAC-SubDo-03. Our studies showed that Mn(II) stimulates bacterial growth and induces sporulation.

Transcriptomic Profiling of the Allorecognition Response to Grafting in the Demosponge Amphimedon queenslandica

open access: yesMarine Drugs, 2017
Sponges, despite their simple body plan, discriminate between self and nonself with remarkable specificity. Sponge grafting experiments simulate the effects of natural self or nonself contact under laboratory conditions.

The Chitinous Skeleton of Ianthella basta Marine Demosponge as a Renewable Scaffold-Based Carrier of Antiseptics

open access: yesPolysaccharides
The chitinous skeleton of the marine demosponge Ianthella basta exhibits a unique network-like 3D architecture, excellent capillary properties, and chemical inertness, making it highly suitable for interdisciplinary research, especially in biomedical ...

Characterization of prokaryotic community dynamics in the sedimentary microenvironment of the demosponge Tentorium semisuberites from Arctic deep waters

open access: yes, 2008
The sedimentary microenvironment of a sessile epibenthic deep-sea species, the small demosponge Tentorium semisuberites, has been investigated to determine its effect on the distribution, physiology and community structure of benthic bacteria and archaea.

Contraction Dynamics and Respiration of Small Single-Osculum Explants of the Demosponge Halichondria panicea

open access: yesFrontiers in Marine Science, 2018
Sponges pump large amounts of seawater through their water canal system, providing both food and oxygen to the sponge body. Sponge pumping activity may show considerable variation as a consequence of contractile behavior, which includes contraction and ...
