Abstract
The D value of commercial biological indicator spore strips using Bacillus stearothermophilus ATCC 7953 was increased by higher calcium concentrations in assay media. The calcium concentration in assay media varied among the manufacturers. The calcium concentration in assay media is an important factor to consider to minimize the variation of D value.
摘要
使用嗜热脂肪芽孢杆菌ATCC 7953的商业生物指示剂孢子条的D值在检测培养基中钙浓度较高时会增加。检测培养基中的钙浓度因制造商而异。检测培养基中的钙浓度是一个需要考虑的重要因素，以尽量减少D值的变化。
