It was identified based on general morphological and anatomical features as <i>Astropecten spinulosus</i>. The antibacterial and antifungal activities were investigated via the standard techniques. Data obtained revealed that the inhibition zones as a factor for antibacterial activity of <i>A. spinulosus</i> ranged between 0 and 18 mm. The highest antibacterial activity was detected against <i>P. aeruginosa</i> (18 mm) for ethanol extract, followed by <i>B. subtlis</i> (14 mm) for methanol extract, then by <i>P. aeruginosa</i> (13 mm) for both ethyl acetate and methanol extract. Different solvent extracts recorded inhibition zones as antifungal activity ranged between 8 to 10 mm. the most suppressed fungus was <i>P. crustosum</i> by acetone and ethanol extracts as 80 and 90%, respectively. Weakly, <i>A. terreus</i> was suppressed by ethanol and methanol extracts of <i>A. spinulosus</i> as 10 and 20%, respectively. The suppression was not taken place against other fungi by any solvent extract. Regarding to investigating the efficacy of some commercial antibiotics (mm), data confirmed that the Gram negative bacteria were more resistant than Gram positive bacteria. On the other side, result of GC-MS/MS of crude extract observed the presence of several bioactive constituents, most of which had antimicrobial activities.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Antimicrobial activity of the sea star (<i>Astropecten spinulosus</i>) collected from the Egyptian Mediterranean Sea, Alexandria","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Antimicrobial activity, Sea star, Astropecten spinulosus, Mediterranean Sea, Alexandria","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-06-12","DateCreate":"2020-06-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":325087,"PubliDate":2020,"Pagination":"507-523","XtraPublOfAnaID":null,"ISBN":null,"Volume":"24","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":225929,"SerRR":"Egyptian Journal of Aquatic Biology and Fisheries.
