Endophytes From Algae, a Potential Source for New Biologically Active Metabolites for Disease Management in Aquaculture

Endophytes are microorganisms that live inside the plant tissue without causing external symptoms. All plants in nature harbor endophytes. Some endophytes produce and secrete biologically active compounds, known as secondary metabolites, which can help host cope with bacterial, fungal, other pest pathogens. isolated from aquatic algae. Diseases detrimental aquaculture industry where chemical pesticides antibiotics widely used an attempt to fish However, ability prevent disease outbreaks is currently extremely limited. Here, we 173 bacterial fungal 16 Mediterranean seaweed 4 algae fresh or thermo-mineral water. We found 88 (51%) biological activity against four common Fifty (29%) caused mortality of at least one these identified 23 bioactive endophytes, 18 Bacilli class. Our findings suggest macroalgae different environments serve a good source potential biocontrol agents diseases. To best our knowledge, there no published studies demonstrating use algal control study may lead finding new molecules for novel environmentally friendly products will solve most challenging problems growing industry: pathogens pests.
