الملخص

The diversity of living marine world offers a substantial potential for the exploitation and thediscovery of bioactive natural substances. Within this considerable chemodiversity,continually exposed to the surrounding marine invertebrates pathogenic microorganisms andonly provided with a primitive immune system, without memory, represent a single reservoirof bioactive molecules defenses. This work aims to explore the antimicrobial properties ofbioactive substances, and hemolymph peptide fraction of the mussel (Mytilusgalloprovincialis) of the Mostaganem region. The protein content was assayed by the Lowrymethod. The antimicrobial activity was tested vis-a-vis a reference range of microorganismsusing the microdilution method. The results obtained showed that the protein contentincreases with mold contamination by E. Coli, also hemolymph has a higher antimicrobialpotency compared to peptides. It turned out that the S. aureus strain is the strain sensitive tothe action of the hemolymph with MIC of 0.7177 g / ml. As regards the results of the peptidemoiety, the behavior of stem was different. The S. typhimurium strain was the most sensitivestrain with an MIC of 0.1495 g / ml. All these results suggest that substances associated withthe immune system may play a critical role in the defense of bivalves.
