The survival of Staphylococcus aureus was determined from inoculated swatches laundered in either a phosphate or a phosphate-substitute detergent. In a Plackett-Burman design study, the independent variables of detergent type, concentration, and variation, wash water temperature, soil load, cycle time, and water hardness were assigned high and low values. Wash water temperatures of 27, 38, 49, and 60 degrees C were employed. Viable bacteria were recovered from macerated swatches. Statistical analysis disclosed that there was no practical difference in the ability of phosphate or phosphate-substitute detergents to reduce the level of S. aureus on the laundered swatches in this controlled design. Analysis did reveal that water temperature was the most significant independent variables. The remaining variables did not appear to have any practical significance upon bacterial reduction. This bacteriological study did not evaluate other essential detergent properties.
通过对接种在使用磷酸盐或磷酸盐替代洗涤剂洗涤的拭子中的金黄色葡萄球菌进行存活情况测定。在一项Plackett-Burman设计研究中，洗涤剂类型、浓度、变化、洗涤水温度、污垢负荷、循环时间和水硬度等自变量被赋予高值和低值。采用了27、38、49和60摄氏度的洗涤水温度。从浸软的拭子中回收活菌。统计分析表明，在该对照设计中，磷酸盐或磷酸盐替代洗涤剂降低洗涤后拭子上金黄色葡萄球菌水平的能力没有实际差异。分析确实表明水温是最显著的自变量。其余变量在减少细菌方面似乎没有任何实际意义。这项细菌学研究没有评估洗涤剂的其他重要特性。
