EM-X is a mixed consortium of beneficial microorganisms of natural occurrence (lactic bacteria, yeast and photosynthetic bacteria). The aim of this study is to evaluate the antimicrobial activity in-vitro of EM-X to the principal pathogens isolated in clinical settings and to understand if it could be a suitable adjuvant to synthetic antibiotics. According the World Health Organization we performed antimicrobial assays to the main pathogens usually found in hospital wards. After antimicrobial testing, EM-X has been shown to be most effective at a concentration of 40 mg/ml four time concentrated than the commercial original solution (10 mg/ml). The EM-X antimicrobial action, although effective against bacteria, has proved to be ineffective against the candida genus. This active range of concentration (mg/ml) may prove a very weak action of EM, but further investigations will be done to separate the active substances form the inactive ones in this complex mixture.
