ANTIFUNGAL ACTIVITY OF LACTIC ACID BACTERIA, ISOLATED FROM (MYTILUS GALLOPROVINCIALIS LAM.) IN THE BULGARIAN BLACK SEA AQUATORY

In the present study we present the results from antifungal activity of Lactic Acid Bacteria, isolated from M. galloprovincialis Lam. from the Bulgarian Black Sea aquatory. The Black Sea mussel (M. galloprovincialis Lam.) is in fact the only marine species grown as aquaculture in the Bulgarian section of the Black Sea. The mussels have an exceptional nutritional value, making them highly suitable for the human diet. The cultivation of sea products, in particular the Black Sea clam, is becoming an important part of the Western Black Sea industry. With increasing of the tourist pressure and the construction activities on the Black Sea coast, maritime pollution increased in the last decades. The pollutants include various pathogenic microorganisms-Escherichia coli, Staphylococcus aureus, Salmonella thyphimurium, Hymeniacidon perlevis, incl. the cholera cause (Vibrioo cholera). Such pathogenic microorganisms are often present in the mussels and can cause the spread of various diseases. In this study 2 isolates Lactic acid bacteria, from M. galloprovincialis Lam have been identified as Lactobacillus sp. and characterized as cultures with promising antifungal activity. The antifungal activity of our new isolates Lactobacillus sp. lineages, seems to be a promising advantage, suggesting their potential applications in different food technologies.
