In this paper, we investigated the lactic acid bacteria's community of the Algerian goat's Jben in order to define and preserve it. This cheese variety is only handmade with raw milk, and a dried flower of Cynara cardunculus is used instead of the animal rennet, it is also restricted in sub-Saharan provinces in Algeria, and no previous studies on its lactic acid bacteria composi- tion have been performed before. Matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) procedure was used to identify 36 lactic acid bacteria isolated from artisanal Jben made from Arabia goat's raw milk in Naâma (Algeria). The results showed the domination of the Enterococcus genus presents with four species: E. durans, E. faecalis, E. hirae and E. faecium. Lactococcus lactis and Leuconostoc mesenteroïdes were also detected. The species identified were favoured by the composition of goat's raw milk microflora used and the artisanal manufacturing process of the cheese. The use of MALDI-TOF MS method provided us with a rapid diagnosis of the Jben lactic acid bacteria's community. This method based on microbial abundant proteins fingerprint diagnosis was chosen for its fast, precise, low cost and less complicated analyse. [ABSTRACT FROM AUTHOR] |
