Preconditioning of Anoxybacillus flavithermus E16 and Geobacillus sp. strain F75 with cations prior to attachment often significantly increased (P ≤ 0.05) the number of viable cells that attached to stainless steel (by up to 1.5 log CFU/cm(2)) compared with unconditioned bacteria. It is proposed that the transition of A. flavithermus and Geobacillus spp. from milk formulations to stainless steel product contact surfaces in milk powder manufacturing plants is mediated predominantly by bacterial physiological factors (e.g., surface-exposed adhesins) rather than the concentrations of cations in milk formulations surrounding bacteria.
在附着之前用阳离子对黄杆菌属（Anoxybacillus flavithermus）E16 和地芽孢杆菌（Geobacillus sp.）菌株 F75 进行预处理，通常会显著增加（P≤0.05）附着在不锈钢表面上的活菌数量（高达 1.5 对数 CFU/cm²），与未经处理的细菌相比。据推测，黄杆菌属和地芽孢杆菌属从乳配方向奶粉制造工厂的不锈钢产品接触表面的转移主要是由细菌生理因素（例如，表面暴露的黏附素）介导的，而不是细菌周围乳配方中阳离子的浓度。
