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.

ATP-bioluminescence was used to evaluate the microbiological quality of water samples collected from the water supply, the water treatment system and from a dairy plant, including ammonia-cooling water and industrial water. For industrial water, there was relation between the ATP-bioluminescence technique and microbial count. There were no differences (p>0.05) between water supply and ammonia-cooling water samples for total and free ATP concentrations nor for the microbial counts. Different microbial ATP concentrations were found for these water samples. The results suggested that the physical chemical quality of ammonia cooling water decreased the RLU measurements slightly. It could be concluded that the total ATP concentration was the most effective... Tipo: Info:eu-repo/semantics/article Palavras-chave: Water quality; ATP-bioluminescence measurement; Food industry. Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132004000300010 Production of pectin lyase by Penicillium griseoroseum in bioreactors in the absence of inducer BJM Piccoli-Valle,Roberta Hilsdorf; Passos,Flávia Maria Lopes; Passos,Frederico José Vieira; Silva,Daison Olzany. Penicillium griseoroseum was grown in bioreactors on mineral medium supplemented with yeast extract and sucrose. The influence of inoculum and carbon source concentrations, aeration and pH on pectin lyase (PL) production, as well as the capacity of P. griseoroseum to produce PL when grown on sugar cane syrup as carbon source were evaluated. Inoculum concentration did not influence PL production. Production was higher in non-aerated than in aerated medium. The best results were obtained using 60 mM sucrose at pH 6.3-7.2. Production using cane syrup 25% (v/v), without yeast extract supplement, was equal to that obtained under the conditions cited above.

ATP-bioluminescence assay was used to evaluate the cleaning and sanitizing procedures of stainless steel milk contact surfaces. Surfaces of a raw milk transportation tank, a raw milk cooling storage tank, an equalization pasteurizing tank, a pasteurized milk storage tank and a pasteurized milk packaging tank, as well as a milk centrifuge were evaluated. The Relative Light Unit (RLU) using a commercial luminometer and mesophilic aerobic counts (CFU.cm-2) on surfaces were determined. There were no significant differences (p>0.05) in RLU on the assessed surfaces before and after the cleaning and sanitizing procedures. Also, there were no significant differences (p>0.05) in CFU.cm-2 on the surfaces before the cleaning and sanitizing procedures, whereas...
