Resistance of Enterobacter sakazakii (Cronobacter spp.) to environmental stresses.

Aim: To gain a better understanding of the survival and persistence of Enterobacter sakazakii in severe environments.

Methods And Results: We evaluated the resistance of Ent. sakazakii to various environmental stresses, including heating, drying, water activity (a(w)), and pH.

Influences of milk components on biofilm formation of Cronobacter spp. (Enterobacter sakazakii).

Aim: To determine the critical component(s) of skim milk for biofilm formation of Cronobacter species.

Methods And Results: Biofilm forming ability of 72 Cronobacter strains in skim milk preparation was assayed by crystal violet staining. The results revealed that whey protein and casein are more important determinants of skim milk for biofilm formation than lactose, although there was a wide variation in biofilm forming ability.

Efficacy of chlorine dioxide gas against Alicyclobacillus acidoterrestris spores on apple surfaces.

Alicyclobacillus acidoterrestris is a thermophilic spore-forming bacterium that spoils acidic juices. In the orchard, apples may be contaminated with spores which can potentially grow in the resulting juice and cause spoilage. This study was undertaken to evaluate the efficacy of gaseous chlorine dioxide against A.

Efficacy of aerosolized peroxyacetic acid as a sanitizer of lettuce leaves.

Aerosolized sanitizer was investigated as a potential alternative to aqueous and gaseous sanitizers for produce. Peroxyacetic acid was aerosolized (5.42 to 11.
