Marine sponges which are known to own multiple functional properties have created significant interest among the researchers due to their biological activities and impending application in different industries .The aim of this study was to obtained bioactive components of sponges. Gelliodes carnosa sponge was collected from Nay Band Bay (Persian Gulf waters) and antimicrobial activities of crud...

The variability of sorbicillin derivatives production by marine Trichoderma sp., isolated from the sponge Agelas dispar J., was studied using six different culture media to find a good medium for biomass production, particularly of trichodimerol, bislongiquinolide and bisvertinol. A simple and rapid convenient method for identification, quantification and validation of the sorbicillin derivativ...

background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

Marine microorganisms have great potential for producing extremozymes. They enter useful relationships like many other organisms in the marine habitat. Sponge–microbial symbiosis enables both sponges and to mutually benefit each while performing their activities within ecosystem. Sponges, because of nature as cosmopolitan benthic epifaunas filter feeders, serve a host extremophilic microorganis...

High Microbial Abundance (HMA) sponges constitute a guild of suspension-feeding sponges that host vast populations of symbiotic microbes. These symbionts mediate a complex series of biogeochemical transformations that fuel the holobiont’s metabolism. Although sponges are aerobic animals, suboxic and anaerobic bacteria are known to reside within their bodies. However, little is known about the c...

Fracture nonunion and delayed union continue to pose challenges for orthopedic surgeons. In the present study, we combined HMGB1 gelatin sponges with MSC sheets to promote bone healing after surgical treatment of rat tibial fractures. The HMGB1 gelatin sponge scaffolds supported the expansion of mesenchymal stem cells (MSCs) and promoted the osteogenic differentiation of MSCs and MSC sheets. Le...

1. Consistently very high regional diversity of tropical marine sponges reflects a combination of high within-habitat diversity and distinctness of species composition among habitats. Distinctive sponge faunas of Caribbean coral reefs and mangroves seem to support the assumption that abiotic factors determine sponge diversity within habitats and faunal differences between habitats because these...

The relationships of the sponge classes are controversial, particularly between the calcareous and siliceous sponges. Specimens of the putative calcarean Eiffelia globosa Walcott from the Burgess Shale show the presence of diagnostic hexactinellid spicules integrated into the skeletal mesh. The arrangement of these spicules in Eiffelia is shown to be precisely equivalent to that of early protos...
