Última An outbreak of staphylococcal food poisoning in the Municipality of Passos, MG, Brazil BABT Carmo,Luiz Simeão do; Dias,Ricardo Souza; Linardi,Valter Roberto; Sena,Maria José de; Santos,Deise Aparecida dos. An outbreak of staphylococcal food poisoning involving 42 people who had eaten a meal at a restaurant in the Municipality of Passos, Minas Gerais, Brazil, is reported. Thirty-one of the individuals became ill with vomiting, diarrhea and dizziness within 30 minutes after eating the meal. The foods suspected were: chicken pancake, rice, beans, tomato sauce and mashed chick-peas. Large numbers (> 2.0x10(8) CFU/g) of enterotoxigenic staphylococci were present in the chicken pancake. These strains produced enterotoxins A, B and D. Swabs from the nasal cavity and throat and from under the fingernails of food handlers were cultured for the detection of enterotoxigenic staphylococci carriers. Four out of five of them were healthy carriers of enterotoxin A, B, C... Tipo: Info:eu-repo/semantics/article Palavras-chave: Staphylococcal enterotoxin; Food poisoning; Staphylococci; Food handlers.

Yeast cells immobilized by entrapment in Ba-alginate gel were investigated for growth pattern and respiratory activity. The oxygen uptake rates (OUR) of cells entrapped in gels with 4% alginate were 5.2 and 23% lower than the OUR of 2% alginate and free cells, respectively. The mass-transfer resistance offered by the matrix and growth of the entrapped cells determine a gradient of nutrients throughout the gel which is responsible for both a lower specific growth rate of immobilized cells with respect to that of free ones, and a heterogeneous biomass distribution, with progressively increasing cellular density from the inside to the outside of the matrix. Gel-matrix polymer concentration affected the maximum oxygen uptake of immobilized growing yeast cells.

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822001000300011 The use of acetonitrile as the sole nitrogen and carbon source by Geotrichum sp. JR1 BJM Rezende,Rachel Passos; Dias,João Carlos Teixeira; Monteiro,Andrea Souza; Carraza,Fernando; Linardi,Valter Roberto. A yeast strain identified as Geotrichum sp. JR1 was able to use acetonitrile as the sole carbon and nitrogen source. The strain grew in 0.5 to 2M acetonitrile. Ammonia generation as enzymatic product during the strain growth indicates the presence of an acetonitrile degrading enzyme. Acetic acid and acetamide were detected during assays with the resting cells cultivated in acetonitrile, indicating the presence of nitrile and amide degrading enzymes. This paper is the first to describe the use of acetonitrile as the sole carbon and nitrogen source by a yeast.
