摘要:A total of 24 strains of lactic acid bacteria were isolated from cow milk and olives brine, out of which 4 strains, having the best criteria of conservation, were selected for their identification and their characterization. These lactic isolates underwent preliminary testing of morphological and biochemical such as: gram reaction, catalase test, mobility and morphology. Other tests were held for characterization such as: fermentation type, fermentation mode of sugars, tolerance to heat, salinity and pH, test of Voges Proskauer, hydrolysis test of Citrate and Arginine. The lactic isolates were classified into 3 species as follows: the BLN3 and BLN4 strains belong to the species Lactobacillus plantarum, the BLN8 strain belongs to Lactobacillus delbrueckii, and the BLN17 strain is classified as Lactobacillus fermentum. BLN3 has only one particularity; she has high tolerance to grow in salt and acid medium.
