“…Decimal dilutions of samples, subjected to agitation by means of an orbital shaker (150 rpm for 1 min), were prepared in Ringer's solution (Sigma-Aldrich, Milan, Italy). Since no high-shear homogenization of the sample was carried out in order to break cell chains of lactic acid bacteria, the CFUs might be slightly underestimated (Champagne et al, 2011). Cell suspensions were plated and incubated as follows: total mesophilic count (TMC) spread plated on plate count agar (PCA), incubated aerobically at 30 C for 72 h; Enterobacteriaceae pour plated on double-layered violet red bile glucose agar (VRBGA), incubated aerobically at 37 C for 24 h; pseudomonads spread plated on Pseudomonas agar base (PAB) supplemented with 10 mg/mL cetrimide fucidin, incubated aerobically at 20 C for 48 h; rod LAB pour plated on de ManRogosa-Sharpe (MRS) agar, acidified to pH 5.4 with lactic acid (5 mol/L) and incubated anaerobically at 30 C for 48 h; coccus LAB pour plated on M17 agar, incubated anaerobically at 30 C for 48 h; yeasts spread plated on dichloran rose Bengal chloramphenicol (DRBC) agar, incubated aerobically at 25 C for 48 h. Count plates were carried out in duplicate for each independent production.…”

“…Los recuentos fueron realizados por duplicado y expresados como UFC g -1 en base seca, para cada condición experimental (Champagne et al, 2011). El porcentaje de viabilidad para cada muestra se calculó según la ecuación (1) (Semyonov, 2010;RodriguezBarona et al, 2012).…”

“…Vários fatores que afetam a viabilidade dos probióticos têm sido relatados em produtos lácteos fermentados, incluindo a acidez titulável, o valor de pH e peróxido de hidrogênio, concentração de oxigênio dissolvido, temperatura de armazenamento, a interação com outros microorganismos contidos nos produtos, a concentração de ácido láctico e acético, além da concentração de proteínas (KAILASAPATHY & SUPRIADI, 1996;CASTRO-CISLAGHI et al, 2012). A sobrevivência é, evidentemente, essencial para que esses microorganismos consigam atingir e povoar o intestino humano, sendo um dos fatores mais importantes para que as bactérias probióticas promovam os benefícios para a saúde do hospedeiro (ANAL & SINGH, 2007;CHAMPAGNE et al, 2011).…”
