Chemical control of epibiosis by Hong Kong sponges: the effect of sponge extracts on micro- and macrofouling communities
The relationship between antifouling metabolite production and epibiosis on the surfaces of the sponges Haliclona cymaeformis, Haliclona sp. and Callyspongia sp. was investigated in this study. Densities of macrofoulers and diatoms were suppressed on the surfaces of all examined sponges, while densities of bacteria on the surfaces of H. cymaeformis and Callyspongia sp. were similar to those on ...
متن کاملA distinctive epibiotic bacterial community on the soft coral Dendronephthya sp. and antibacterial activity of coral tissue extracts suggest a chemical mechanism against bacterial epibiosis.
Abstract Different bacterial community profiles were observed on the soft coral Dendronephthya sp. and an inanimate reference site using terminal restriction fragment length polymorphism analysis of bacterial community DNA. To correlate the observation with a chemical defense mechanism against bacterial epibiosis, antibacterial effects of coral tissue extracts and waterborne products of coral-a...
متن کاملA bacterial culture-independent method to investigate chemically mediated control of bacterial epibiosis in marine invertebrates by using TRFLP analysis and natural bacterial populations.
It has been postulated that a variety of physically undefended marine invertebrates have evolved strategies to control microbial epibiosis chemically. Ecologically meaningful experiments that demonstrate chemically mediated antibacterial effects are difficult due to the small number of cultivable bacteria. Based on the example of three sponges, this study introduces a culture-independent method...
متن کاملRelationships Between Chemical Defense and Ecology in Benthic Ascidians
Thirty-five species of nearshore, benthic ascidians were collected in Bermuda and notes were made on their habitat, microhabitat, susceptibility to epizoic recruitment, morphology, and acidity. Twenty-four ascidian species were later analyzed for vanadium and iron contents. Ten species had vanadium concentrations of over 100 ppm d. W. (dry weight); three species had vanadium concentrations of o...
متن کاملChemical Studies on Bacterial Agglutination
1. A method, conforming to the criteria of quantitative analytical chemistry, is described for the estimation of the agglutinin content of antisera. Examples are given of the application of the method to various antipneumococcus sera. 2. This new, absolute method is discussed with regard to its relation to the commonly used relative methods.
