Última Acid and low temperature treatments on Salmonella Enteritidis inoculated in pork and its subsequent survival in simulated gastric fluid Ciência Rural Silva,Simone Quintão; Santos,Miriam Teresinha dos; Paes,Simone Albino; Vanetti,Maria Cristina Dantas. ABSTRACT: The objective of this study was to evaluate the acid resistance of Salmonella enterica serovar Enteritidis (S. Enteritidis) in stored pork and in simulated gastric fluid (SGF). A culture of S. Enteritidis was subjected to acid treatment prior to inoculation into pork, stored under refrigeration at frozen temperatures and exposed to SGF. The S. Enteritidis CCS3 and ATCC 13076 strains previously subjected to acid treatment (at pH 4.0-5.0) were inoculated in pork and stored at 4°C and -18°C. Storage at 4ºC did not affect the populations of both S. Enteritidis strains. After 84 days at -18°C, the mean population of both CCS3 and ATCC strains were reduced by 0.8 and 1.5 log cycles, respectively. Prior acid treatment did not enhance the survival of...

A presença de microrganismos indicadores de contaminação na linha de abate de frangos foi determinada visando identificar os possíveis pontos de controle e oferecer uma opção para o monitoramento ou a verificação pelo sistema "Análise de Perigos e Pontos Críticos de Controle" (APPCC). A contaminação superficial das carcaças foi determinada pela enumeração de microrganismos aeróbios mesófilos, coliformes totais, coliformes termotolerantes e de Escherichia coli nas seguintes fases de abate: A - antes do primeiro chuveiro de higienização, B - após o primeiro chuveiro, C - após a evisceração manual, D - após o chuveiro de lavagem final e E - na saída do pré-resfriamento. Não houve diferença significativa (P<0,05) entre as médias de mesófilos, coliformes... Tipo: Info:eu-repo/semantics/article Palavras-chave: Mesófilos; Coliformes; Abate de frangos; APPCC. Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84782008000700023 ANTIBACTERIAL ACTIVITY OF LENTINULA EDODES GROWN IN LIQUID MEDIUM BJM Ishikawa,Noemia Kazue; Kasuya,Maria Catarina Megumi; Vanetti,Maria Cristina Dantas. The antibacterial activity of 35 isolates of Lentinula edodes, a shiitake mushroom, against Bacillus subtilis was evaluated by diffusion technique in agar with a semi-solid overlay. All isolates inhibited B. subtilis and the isolate Le1 promoted the formation of the largest inhibition zone. L. edodes Le1 also presented antibacterial activity against foodborne pathogens and food contaminant bacteria, particularly Gram-positive species. The antibacterial activity of the culture filtrate after 18-25 days of cultivation of L. edodes in broth at 25ºC was high. The inhibitory activity was observed only in the organic layer when the culture filtrate was partitioned between ethyl acetate and water, suggesting that the inhibitory substances have low polarity. The... Tipo: Info:eu-repo/semantics/article Palavras-chave: Antibacterial activity; Lentinula edodes; Shiitake. Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822001000300008 Antimicrobial activity and mineral composition of shiitake mushrooms cultivated on agricultural waste BABT Casaril,Kérley Braga Pereira Bento; Kasuya,Maria Catarina Megumi; Vanetti,Maria Cristina Dantas. The antimicrobial activity and mineral composition of shiitake mushrooms were evaluated in four isolates of Lentinula edodes. Mushrooms were cultivated on artificial logs, based on eucalyptus sawdust enriched with 20% rice, wheat, or soybean bran, or combination of 10% of two of these supplements. The substrates were humidified with a 0.1% mate tea extract or water. Logs of Eucalyptus grandis were also used to cultivate the shiitake mushrooms. The antimicrobial activity of an aqueous extract, corresponding to 40 mg of mushroom dry matter, was in some cases, depending on the isolate, able to inhibit both Bacillus subtilis and Escherichia coli K-12, independent of substrate composition or the growth stage of the mushrooms. Nitrogen, phosphorus, potassium,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Antibacterial property; Lentinula edodes; Mineral nutrients; Sawdust-based substrate; Mushrooms. Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132011000500017 Effect of eugenol on growth and listeriolysin o production by Listeria monocytogenes BABT Filgueiras,Cristina Tostes; Vanetti,Maria Cristina Dantas. The inhibitory effect of eugenol, a naturally occurring compound mainly present in the essential oil fraction of cloves, was studied on the growth and listeriolysin O (LLO) production by Listeria monocytogenes. Potassium efflux from cells promoted by eugenol was also determined after 24 h incubation in phosphate buffered saline. Eugenol promoted a delay on the growth of L. monocytogenes at concentrations of 100, 300 and 500 µg mL-1and above 800 µg mL-1 the effect was bactericidal. Production of LLO by L. monocytogenes in the presence of eugenol was reduced 80-100%. An accumulation of external K+ was observed above 300 µg mL-1 of eugenol which indicated that the cell membrane was affected. The results showed the effectiveness of eugenol in controlling...

ABSTRACT The ability of pathogens to survive cheese ripening is a food-security concern. Therefore, this study aimed to evaluate the performance of two alternative methods of analysis of Listeria during the ripening of artisanal Minas cheese. These methods were tested and compared with the conventional method: Lateral Flow System™, in cheeses produced on laboratory scale using raw milk collected from different farms and inoculated with Listeria innocua; and VIDAS®-LMO, in cheese samples collected from different manufacturers in Serro, Minas Gerais, Brazil. These samples were also characterized in terms of lactic acid bacteria, coliforms and physical-chemical analysis. In the inoculated samples, L. innocua was detected by Lateral Flow System™ method with... Tipo: Info:eu-repo/semantics/article Palavras-chave: Listeria; Raw milk cheese; Alternative methods. Ano: 2016 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822016000300749 Thermostability of xylanolytic enzymes produced by Lentinula edodes UFV70 BJM Ribeiro,Liliane Fraga Costa; Vaz,Marcelo Gomes Marçal Vieira; Chaves-Alves,Virgínia Maria; Vanetti,Maria Cristina Dantas; Kasuya,Maria Catarina Megumi; Passos,Flávia Maria Lopes; Nascimento,Antônio Galvão do. Xylanolytic enzymes produced by Lentinula edodes UFV70, cultivated in eucalyptus sawdust/rice bran medium, were stable at 50, 60 and 65ºC for 21 hours, losing only 15-25% activity. Fungus incubation at 50ºC for 12 hours and at 65ºC for 24 hours increased the amount of xylose produced.

The growth of Salmonella enterica subs. enterica sorovar Typhimurium at 25°C was monitored in industrialized and hospital formulated enteral feeds and the results were used to validate the mathematical model of Salmonella growth presented by the Pathogen Modeling Program (PMP) 7.0 (USDA-USA). The generation time of Salmonella in enteral feeds ranged from 21 to 34.8 min and, the maximum growth rate (µmax) varied from 1.28 to 1.95 h-1, resulting in a population increase from 5 to 6 log10 cycles within 14 to 24 h incubation. Growth was faster in the hospital formulated feed containing vegetables and eggs. The growth kinetic's parameters as lag phase; µmax and maximum population density (MPD) were similar to those predicted by the PMP 7.0, with exception of...
