1. It contains many glycosides and glycoalkaloids, and also has broad antimicrobial activity . 2. Derivatives of thymol and carvacrol with increased antimicrobial activities have been developed. 3. Mammalian defensins also do not require disulfide bonds to exhibit antimicrobial activity . 4. Studies have shown that disulfide bonds are not required for antimicrobial activity . 5. Making a surface superhydrophobic represents an efficient means of imparting antimicrobial activity . 6. The essential oil exhibited antimicrobial activity to varying degrees against all tested strains. 7. Granulysin has antimicrobial activity against M . tuberculosis and other organisms. 8. Some strains produce bacteriocins named weissellicins which show antimicrobial activity against other bacteria. 9. This inhibition restores the antimicrobial activity of ?-lactam antibiotics against lactamase-secreting resistant bacteria. 10. First isolated in 1969, and characterized structurally in 1973, velleral has antimicrobial activity .
