ABSTRACTBACKGROUND Nowadays the treat infection of bacterial diseases faced limitations because of the harm of industrial artificial antibiotics for the digestive system and immune system. Consequently, the scientists seek to replace conventional anti-biotics whit natural ones.AIM OF STUDY The central thesis of this study is to identify potential antimicrobial properties of the Sargassum cristaefolium and Dictyota cervicornis extracts.MATERIAL AND METHOD Water-methanol, n-hexane, Ethyl acetat, methanol and water extracts of two marine macroalgae from chahbahar bay (Iran) were weighed up in terms of antimicrobial activity by Agar disk diffusion, MIC and MBC methods against (L.monocytogens as gram-positive bacteri, and (E.coli and P. aeruginosa as gram-negative bacteria).RESULTS According to the obtained results, the hot water extract in S. cristaefolium and D.cervicornis none of the strains examined is of antibiotic effects. Ethyl acetat extract in comparison with other extracts displayed better antibacterial activity (P<0.05). Highest zone of inhibition (14 mm) was recorded for Ethyl acetat extract of S. cristaefolium contrary to L. monocytogenes. Maceration method extracts did not display any effect towards the studied bacteria.CONCLUSION For extracting antimicrobial compounds, the ultrasound method was a successful method.

AbstractIn mariculture, diseases of microbial origin can cause significant economic losses worldwide; the evolution of microorganism resistance to antibiotics has resulted in a growing need for new antibacterial compounds that are effective in veterinary medicine and characterized by limited undesirable side effects. Increased attention has recently been turned to seaweeds as a promising source for metabolites with antimicrobial activity. Vibriosis is a common disease, caused by bacteria of the genus Vibrio, that can result in high mortality in aquaculture. The aim of this study was to identify seaweeds with antibacterial activity against some pathogenic Vibrio species, in order to identify a possible alternative to the commonly used antibiotics in aquaculture. Chloroform/methanol lipidic extracts of six seaweed species (Chaetomorpha linum, Cladophora rupestris, Gracilaria dura, Gracilaria gracilis, Gracilariopsis longissima, Ulva prolifera) were tested for their antibacterial activities against six fish pathogenic Vibrio species using the disc diffusion method. Different susceptibilities to lipidic algal extracts were observed. All six of the seaweed extracts tested demonstrated inhibition of Vibrio ordalii. The best was that from Gracilariopsis longissima, showing activity against Vibrio ordalii, Vibrio salmonicida, Vibrio alginolyticus and Vibrio vulnificus. The results confirmed the potential use of seaweed extracts as a source of antibacterial compounds or as a health-promoting feed for aquaculture.
