This study investigates the isolation and identification of beneficial bacterial strains from Musk. Also, the antagonistic effect of different natural animal Musk concentrations and the filtrates produced from the growth of bacterial which isolated from it on some pathogenic microorganisms was studied. Five isolates were selected and identified, namely Lactobacillus acidophilus (a1), Lactobacillus acidophilus (a2), Latctococcus lactis sub sp lactis (b1), Latctococcus lactis sub sp lactis (b2) and Streptococcus thermophilus. Results also indicated that Musk extract and filtrates of its strains growth has an inhibition and bactericidal effects on the growth of some pathogenic microorganisms such as Staphylococcus aureus and Penicillium puberulum fungus. Musk itself is more effective on the growth of pathogens than the effect of strains isolated from it. Antagonistic effect of P.puberulum showed more pronounced inhibitory effect than S. aureus. Results also showed that the filtrates have the ability to inhibit the growth of tested microorganisms.
