BACTERIA CULTURE MEDIUM AND USE THEREOF

摘要

The present invention has publicized a bacteria culture medium. In common bacteria culture medium, one kind or several kinds of ²-lactam antibiotics and/or the salts thereof were premixed. The ²-lactam antibiotics and/or the salts thereof premixed in the bacteria culture medium is slightly soluble in water at 25°C and the solubility is less than 10mg/ml. The concentrations of the ²-lactam antibiotics premixed in the culture medium are greater than the solubility of the used ²-lactam antibiotics at 25°C, but are less than 100mg/ml. The bacteria culture medium can be used to selectively culture bacteria with ²-lactam antibiotic resistance and can be stored for a long time.
