چکیده

sponges are the simplest multicellular animals that lack defense mechanisms and rely on chemical defense  that have been used by mankind to develop antimicrobial drugs against diseases.  the present study was designed to demonstrate the antibacterial and antifungal activities of marine sponge dysidea pallescens semipolar and nonpolar extracts. in this study, d. pallescens were collected from hengam island in the persian gulf. the extracts were produced by bligh and dyer method. broth dilution methods were used to check the antimicrobial activity of d. pallescens extracts against escherichia coli (atcc 15224), pseudomonas aeruginosa (atcc 25619), staphylococcus aureus aureus (atcc 1764), bacillus subtilis pizizenii (atcc 6633), candida albicans (atcc10231) and aspergillus fumigates (ptcc5009). the results showed diethyl ether extract has bactericidal activity against s. aureus aureus (mbc=10mg/ml) and b. subtilis spizizenii (mbc=20mg/ml). d. pallescens diethyl ether extract showed a very weak antifungal activity but methanol extract showed fungicidal activity against a. fumigates (mfc=5mg/ml) and c. albicans (mfc=1.5 mg/ml). therefore nonpolar-semipolar secondary metabolites of d. pallescens solutions in diethyl ether have shown significant antibacterial activity and polar- secondary metabolites solutions in methanol have shown significant antifungal activity.

Investigation of antibacterial activities of sponge Axinella sinoxea’s extracts from Larak Island, Persian Gulf

Sponges are the most primitive and simplest multicellular animals. These organisms don’t have any mechanical defense system, so their early appearance in evolution has given them a lot of time for the development of advanced secondary metabolites as chemical defense system. Sponges have the potential to provide drugs from chemical components against diseases, such as antibacterial. Antimicrobia...

Secondary Metabolites from Polar Organisms

Polar organisms have been found to develop unique defences against the extreme environment environment, leading to the biosynthesis of novel molecules with diverse bioactivities. This review covers the 219 novel natural products described since 2001, from the Arctic and the Antarctic microoganisms, lichen, moss and marine faunas. The structures of the new compounds and details of the source org...

Polarity inversion in polar-nonpolar-polar heterostructures.

We have observed an epilayer-thickness-dependent polarity inversion for the growth of CdTe on Sb(Bi)/CdTe(111)B. For films with Sb(Bi) thicknesses of less than 40 A (15 A), the CdTe layer shows a B (Te-terminated) face, but it switches to an A (Cd-terminated) face for thicker layers. On the other hand, a CdTe layer grown on Bi(Sb)/CdTe(111)A always shows the A face regardless of Sb or Bi layer ...

Antibacterial activity of actinomycetes isolated from native sponge of Persian Gulf (Kharku Island) against pathogens

Resistant of pathogens to common antibiotics is a major global problem, and efforts discover new antibiotics from less known resources, is an inevitable. Native sponges of Persian Gulf have high potential in the field of medical biology, but have received little attention. In this study, actinomycetes that capable to produce anti-bacterial metabolites isolated and examined. Two sponges of Persi...
