摘要
通过扫描电镜和测定数据表明,在不锈钢表面形成的沙门氏菌生物被膜培养8h后细菌密度达到3×106cfu/cm2;沙门氏菌以生物被膜的形式生长比以浮游形式对二氧化氯具有更强的抵抗能力;胰酶大豆肉汤(tryptonesoy broth,TSB)等营养物质能明显减弱生物被膜对二氧化氯的敏感性。
Biofilm formation of Salmonella sp. （AS 1. 1552） on stainless steel surface were observed with scanning electronic microscope （SEM） and measured through its growth curve. The results showed that Salmonella sp. biofilm on stainless steel surface entered the stationary phase after 8 h incubation and the cell density was 3 × 10^6 cfn ·cm^ -2 The bacterial cells on the biofilm had higher resistance to chlorine dioxide than those in suspension. Tryptone soy broth （TSB） obviously reduced the sterilization effect of chloride dioxide.
