Isolation of lactic acid bacteria as probiotic for humans / Mohamad Halif Mohamad Yusof
In recent years, there has been considerable interest and research on the use of probiotics, for disease treatment or health promotion. However much remains to be done on the selection of strains that actually possess characteristics of true probiotic microorganisms.The present study was carried out...
