“…For example, the ethanol extract of Gracilaria corticata from India proved to be highly active against Vibrio cholerae and V. parahaemolyticus but lesser against Pseudomonas aeruginosa and Shigella flexneri [38]. Gracilaria fisheri was studied for its antimicrobial activity by [39], who reported that the ethanol, the hexane, the chloroform and the methanol extract all possessed potent antimicrobial activity against V. harveyi, but the ethanol extract resulted the greatest activity with the lowest concentration. In Iberian thalli of G. dura, the solid extract obtained by pounding the fresh material, without any solvent, showed a lowmedium activity against Gram-positive and Gramnegative bacteria and yeasts, but it was not tested against any Vibrio species [31].…”

“…Ethanol was also used for thalli of Gracilaria fisheri from India, the extract of which showed a high inhibition against V. harveyi [39]. Since the chlorophorm/methanol extracts of the Mar Piccolo of Taranto seaweeds were not effective against V. harveyi, we suppose that in this case the solvent used for the extraction was not suitable for extracting the antimicrobial compounds.…”

Antibacterial activity of marine macroalgae against fish pathogenic Vibrio species

In 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.

“…Gracilaria has historically been a commercial source of food grade and biotechnological grade agar, and its economic value is very stable (Yarish and Pereira 2008). Beyond its traditional uses, Gracilaria may be suitable for biofuel production (Notoya 2010), an ingredient for fish feeds , Kanjana et al 2011, Fleurence et al 2012 and employed for nutrient bioextraction in integrated multi-trophic aquaculture (IMTA) systems (Abreu et al 2009, 2011a, 2011b, 2011c, Yarish and Kim 2013.…”

“…This potential was evidenced in the present study by the inhibition of V. xuii, V. brasiliensis and V. navarrensis, in addition to V. parahaemolyticus. In this context, the antibacterial activity of red seaweed (Gracilaria fisheri) was reported by Kanjana et al (2011), who verified that ethanol, methanol and chloroform extracts showed activity against a virulent strain of V. harveyi. Extracts prepared with HM and UF were only bioactive against vibrio strains.…”

ABSTRACT. The antibacterial activity of ethanol, methanol, hexane and acetone-based extracts of the macroalgae Padina gymnospora (PG), Hypnea musciformes (HM), Ulva fasciata (UF) and Caulerpa prolifera (CP) was investigated. The disk diffusion method was used to evaluate the algae antimicrobial effect against standard strains of Vibrio parahaemolyticus, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella enterica and five virulent antibiotic-resistant strains of V. brasiliensis, V. xuii and V. navarrensis (isolated from the hemolymph of Litopenaeus vannamei). Ethanol extracts of PG and HM inhibited all Vibrio strains. E. coli and P. aeruginosa were only susceptible to ethanol extracts of PG. Among the methanol extracts, only UF was bioactive, inhibiting V. navarrensis. The observed inhibitory effect of ethanol extracts of PG, HM and UF against virulent antibiotic-resistant bacteria suggests these macroalgal species constitute a potential source of bioactive compounds.
