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