Diversity and density of lactic acid bacteria isolated from Algerian
raw goats' milk in arid zones were studied by determination of
morphological, cultural, physiological and biochemical characteristics.
206 lactic acid bacterial strains were isolated, with 115 of them
belonging to lactic acid cocci and others to the genus, Lactobacillus
. The representative species of the total cocci were
Lactococcus sp. (76.16%), Streptococcus thermophilus
(14.78%) and Leuconostoc sp. (8.6%). The dominating species is
Lactococcus lactis subsp. Lactis . Lactobacilli species found
in local raw goats' milk and their proportion were: Lb. curvatus
(25.25%), Lb. helviticus (10.98%), Lb. plantarum (9.89%), Lb. reuteri
(9.89%), Lb. casei (7.69%), Lb. brevis (5.49%), Lb. bulgaricus (5.49%)
Lb. paracasei (4.39%) and Lb. acidophilus (2.19%)
