The paper reports the use of microelectrodes to measure O2 penetration in different aged colonies of Bacillus cereus, Escherichia coli and Staphylococcus albus. In young (18 h) colonies of B. cereus and E. coli O2 disappeared at depths of 25-30 micron and 35-40 micron respectively. In young S. albus colonies, O2 reached a minimum but was never completely absent. As colonies aged (24-168 h) the depth to which O2 penetrated increased.
该论文报道了使用微电极测量不同生长阶段的蜡样芽孢杆菌、大肠杆菌和白色葡萄球菌菌落中氧气的渗透情况。在蜡样芽孢杆菌和大肠杆菌的年轻(18小时)菌落中,氧气分别在25 - 30微米和35 - 40微米的深度消失。在年轻的白色葡萄球菌菌落中,氧气含量达到最低值,但从未完全消失。随着菌落老化(24 - 168小时),氧气渗透的深度增加。
