- Chemical sanitizers to control biofilms formed by two Pseudomonas species on stainless steel surface Danila Soares CAIXETA Thiago Henrique SCARPA Danilo Florisvaldo BRUGNERA Dieyckson Osvani FREIRE Eduardo ALVES Luiz Ronaldo de ABREU Roberta Hilsdorf PICCOLI Agrociencias Biofilm aeruginosa fluorescens chemical sanitizers The biofilm formation of Pseudomonas aeruginosa and Pseudomonas fluorescens on AISI 304 stainless steel in the presence of reconstituted skim milk under different temperatures was conducted, and the potential of three chemical sanitizers in removing the mono-species biofilms formed was compared. Pseudomonas aeruginosa cultivated in skim milk at 28 °C presented better growth rate (10.4 log CFU.mL –1 ) when compared with 3.7 and 4.2 log CFU.mL –1 for P. aeruginosa and P. fluorescens cultivated at 7 °C , respectively. Pseudomonas aeruginosa formed biofilm when cultivated at 28 °C. However, only the adhesion of P . aeruginosa and P. fluorescens was observed when incubated at 7 °C . The sodium dichloroisocyanurate was the most efficient sanitizer in the reduction of the adhered P. aeruginosa cells at 7 and 28 °C and those on the biofilm, respectively. The hydrogen peroxide was more effective in the reduction of adhered cells of P . fluorescens at 7 °C. 2012 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395940112021 en http://www.redalyc.org/revista.oa?id=3959 Ciência e Tecnologia de Alimentos application/pdf Sociedade Brasileira de Ciência e Tecnologia de Alimentos Ciência e Tecnologia de Alimentos (Brasil) Num.1 Vol.32
