Última Interference of some organic substances and microorganisms adhered to stainless steel in ATP-bioluminescence measurement BABT Simm,Erny Marcelo; Andrade,Nélio José de; Mendonça,Regina Célia Santos; Passos,Frederico José Vieira; Chaves,José Benício Paes. Adhesion of organic substances and microorganisms on stainless steel surface was evaluated. The log RLU measurement was affected at a lower or higher degree, by type or concentration of the organic substances (casein, lipid, sucrose and their combinations) adhered to surface. However, if the samples analyzed were from the food processing surfaces, they would have been considered to be under satisfactory hygienic conditions with log RLU < 2.18 (< 150 RLU). The log RLU measurements of Staphylococcus carnosus-adhered surfaces, combined with or without the organic substances, were higher (p<0.05) than those of the Bacillus subtilis spores-adhered surface, regardless of the concentration. The samples taken from the surfaces adhered with the casein,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hygiene monitoring; ATP-bioluminescence measurement; Adhesion on stainless steel.

Tecnol. Aliment. Ferreira,Andreza Angélica; Tette,Patrícia Amaral Souza; Mendonça,Regina Célia Santos; Soares,Ariana de Souza; Carvalho,Márcia Maria De. Staphylococcus spp. can survive in biofilms for long periods of time, and they can be transferred from one point to another and cause environmental contamination in food processing. The aim of this study was to detect Staphylococcus strains isolated from a poultry processing plant by the presence of adhesion genes and the phenotypic production of exopolysaccharide. In the present study, the production of exopolysaccharide and the presence of adhesion genes in 65 strains of Staphylococcus spp. were evaluated. All strains of Staphylococcus spp. produced exopolysaccharide, as confirmed by formation of black and opaque colonies in Congo Red Agar. The variation of sucrose content was critical for the production of exopolysaccharide in Congo Red Agar since at...

This research deals with the investigation of electrocoagulation (EC) treatment of wastewater from a dairy plant using aluminum electrodes. Electrolysis time, pH, current density and distance between electrodes were considered to assess the removal efficiency of chemical oxygen demand (COD), total solids (TS) and their fractions and turbidity. Samples were collected from the effluent of a dairy plant using a sampling methodology proportional to the flow. The treatments were applied according to design factorial of half fraction with two levels of treatments and 3 repetitions at the central point. The optimization of parameters for treating dairy industry effluent by electrocoagulation using aluminum electrodes showed that electric current application for...
