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.
本发明公开了一种细菌培养基。在普通细菌培养基中,预混了一种或几种β-内酰胺类抗生素和/或其盐类。预混在细菌培养基中的β-内酰胺类抗生素和/或其盐在 25 摄氏度时微微溶于水,溶解度小于 10 毫克/毫升。培养基中预混合的 β-内酰胺类抗生素的浓度大于所用 β-内酰胺类抗生素在 25 摄氏度时的溶解度,但小于 100 毫克/毫升。该细菌培养基可用于选择性培养具有β-内酰胺类抗生素耐药性的细菌,并可长期保存。
