RESUMO
Em 10 fazendas da região da Serra do Salitre, MG, foram coletadas amostras de leite, soro fermentado (pingo), coalhada e queijo frescal para avaliar a microbiota de bactérias láticas e leveduras presentes. Uma diversidade menor de bactérias láticas foi observada durante a produção do queijo quando comparada à de leveduras. As espécies de bactérias láticas mais freqüentes foram Lactococcus lactis, Enterococcus spp., Enterococcus faecalis e Streptococcus agalactiae e de leveduras foram Debaryomyces hansenii e Kluyveromyces lactis. Apenas as populações de Enterococcus spp., Enterococcus faecalis e Leuconostoc mesenteroides apresentaram aumento significativo durante a produção do queijo. As espécies de bactérias láticas e leveduras encontradas nos diferentes substratos estudados podem ser responsáveis pelas características de aroma e sabor do queijo artesanal da Serra do Salitre.
ABSTRACT
Samples of milk, curd, cheese whey, and cheese were collected in 10 farms located at the region of Serra do Salitre, Minas Gerais state. These samples were studied in relation to their lactic acid bacteria and yeast populations. The diversity of lactic acid bacteria species was lower than the diversity of yeasts in these samples. The isolated lactic acid bacteria were Lactococcus lactis, Enterococcus spp., Enterococcus faecalis, and Streptococcus agalactiae; and the yeasts were Debaryomyces hansenii and Kluyveromyces lactis. Only the species Enterococcus spp., Enterococcus faecalis, and Leuconostoc mesenteroides showed an increase in their populations during the production of the artisanal cheese. Lactic acid bacteria and yeasts found in this study could be responsible by the sensorial characteristics of the artisanal cheese produced in the region of Serra do Salitre.
