Lactic acid bacteria (LAB) and their bacteriocins as alternative biotechnologic...
Camargo, Anderson C.; Todorov, Svetoslav D.; Chihib, N. E.; Drider, D.; Nero, Luís A.Bacteriocins are antimicrobial peptides produced by bacteria Gram-negative and Gram-positive, including lactic acid bacteria (LAB), organisms that are traditionally used in food preservation practices. Bacteriocins have been shown to have an aptitude as biofilm controlling agents in Listeria monocytogenes biofilms, a major risk for consumers and the food industry. Biofilms protect pathogens from sanitization pr...
Genotypic and antimicrobial characterization of pathogenic bacteria at differen...
Loiko, Márcia R.; Paula, Cheila M.D. de; Langone, Ana C.J.; Rodrigues, Rochele Q.; Cibulski, Samuel; Rodrigues, Rogério de O.; Camargo, Anderson C.Meat can be contaminated in different stages of the slaughtering process and the identification of these stages is the starting point to implement adequate control measures. The objectives of this study were to assess the presence of pathogenic microorganisms in cattle carcasses, to identify the most important contamination points of the slaughtering process, and to evaluate the possible risk factors related to...
Enumeration of starter cultures during yogurt production using Petrifilm™ AC pl...
Gonçalves, Marília M.; Freitas, Rosangela; Nero, Luís A.; Carvalho, Antônio F.The efficiency of Petrifilm TM AC (3M Microbiology, St. Paul, MN, USA) associated with the broths M17 and de Mann-Rogosa-Sharpe (MRS) at pH 5.4 was evaluated to enumerate Streptococcus salivarius subsp. thermophilus and Lactobacillus delbrueckii subsp. bulgaricus during the yogurt production. Commercial and reference strains of these microorganisms were experimentally inoculated in nonfat milk and incubated at ...
Combined effect of bacteriocin produced by Lactobacillus plantarum ST8SH and va...
Todorov, Svetoslav D.; Paula, Otávio A.L.de; Camargo, Anderson C.; Lopes, Danilo A.; Nero, Luís A.não foi possível encontrar todas as informações de volume e serie apenas o mês e o ano da publicação.; The Listeria monocytogenes strains selected in the present study exhibited similar behavior in biofilm formation, independently of the tested conditions (bacteriocin from L. plantarum ST8SH, vancomycin, propolis (a natural antimicrobial product) and EDTA (chelating agent)), individual or in associations. The i...
Evaluation and implementation of good pratices in main points of microbiologica...
Fagan, Éder Paulo; Beloti, Vanerli; Barros, Márcia A. F.; Muller, Ernst E.; Nero, Luís A.; Santana, Elsa H. W.; Magnani, Douglas FurtadoIn order to improve the microbiological quality of Brazilian milk and dairy products some measures have been implemented in the milk-producing sector throughout the years, such as milk refrigeration and bulk collection. Refrigeration is a very efficient procedure, however allows psychrotrophics multiplication, which are largely found in milk produced in poor hygienic conditions. To assure and improve the microb...
