ABSTRACT Marine sponges has been a large reservoir of microbial diversity, with the presence of many species specific populations as well as producing biologically active compounds, which has attracted great biotechnological interest. In order to verify the influence of the environment in the composition of the bacterial community present in marine sponges and biotechnological potential of bacteria isolated from these organisms, three species of sponges and the waters surrounding them were collected in different beaches of Rio de Janeiro, Brazil. The profile of the bacterial community present in sponges and water was obtained by PCR-DGGE technique and the biotechnological potential of the strains isolated by producing amylase, cellulase, protease and...

ABSTRACT Marine sponges are a rich source of bioactive natural products with multiple pharmacological properties. In this study, the anti-inflammatory and antinociceptive effects of extracts obtained from Aplysina caissara, Haliclona sp. and Dragmacidon reticulatum were evaluated by using the writhing test and formalin-induced mouse paw edema model in mice. All extracts were administered via oral pathway in the doses of 60 and 90 mg/kg. In the writhing test the pre-treatment with all sponges resulted in significant inhibition of the acetic acid-induced response, suggesting an antinociceptive effect. The formalin test showed that the extracts from A. caissara, Haliclona sp. and D. reticulatum, in the tested doses, did not affect the first formalin phase,...

Isolation and cultivation of fungal strains from in vitro cell cultures of two marine sponges (Porifera: Halichondrida and Haplosclerida)

Despite the large number of reports describing sponge-microbe associations, limited knowledge is available about associated fungi and their relationships with the hosts. In this work, specific fungal strains were obtained directly from in vitro sponge cell cultures (primmorphs) and single sponge cells (cytospins) and compared with those obtained from whole tissue preparations. A total of 27 fungal strains were isolated from the marine sponges Hymeniacidon heliophila and Haliclona melana. Fifteen strains, nine from H. heliophila and six from H. melana, were obtained from whole tissue and were considered as possible mesohyl associated or transient fungi. Twelve strains were isolated from in vitro sponge cell cultures (primmorphs) and were, therefore,...

Diversity of the candidate phylum Poribacteria in the marine sponge Aplysina fulva
Provedor de dados: Brazilian Journal of Microbiology
Autores: Hardoim,C.C.P.; Cox,C.J.; Peixoto,R.S.; Rosado,A.S.; Costa,R.; Elsas,J.D. van.
Poribacterial clone libraries constructed for Aplysina fulva sponge specimens were analysed with respect to diversity and phylogeny. Results imply the coexistence of several, prevalently "intraspecific" poribacterial genotypes in a single sponge host, and suggest quantitative analysis as a desirable approach in studies of the diversity and distribution of poribacterial cohorts in marine sponges.
