Abstract

Beta-lactamase type I is reported for the first time to occur in the sporulated form in a penicillin-resistant Bacillus species. The enzyme was readily characterized from the B. cereus 5/B line (ATCC 13061) by mass spectrometry and two-dimensional gel electrophoresis.

摘要

首次报道I型β-内酰胺酶以芽孢形式存在于一株耐青霉素的芽孢杆菌属细菌中。通过质谱分析和二维凝胶电泳，很容易从蜡样芽孢杆菌5/B株（ATCC 13061）中鉴定出该酶。
