This study aimed to isolate lactic acid bacteria (LABs) of technological interest from Moroccan camel milk and select starter or adjunct culture for dairy product manufacturing. The phenotypic and biochemical identification of 47 isolates revealed the existence of ten Lactococcus lactis, eleven Lactobacillus plantarum, three Lactobacillus brevis, two Lactobacillus paracasei, eleven Enterococcus spp., seven Lactococcus spp. and two Lactobacillus spp. Our strains showed a fast acidifying ability (ΔpH ranged between 0.69 ± 0.01 and 1.22 ± 0.05 after 6 h), high proteolytic and autolytic activities (1.93 ± 0.02 to 9.9 ± 0.022 mM glycine and 15.21 ± 2.21% to 83.24 ± 1% respectively), and an important lipolytic and free radical scavenging capacity. Furthermore, they were able to use citrate, to produce exopolysaccharide, and they exhibited antibacterial activity against Gram-negative and Gram-positive pathogenic bacteria and had no hemolytic activity. This study has shown that Moroccan camel milk represents a rich biotope of interesting LABs for dairy products industry.

本研究旨在从摩洛哥骆驼奶中分离出具有技术意义的乳酸菌 (LAB)，并选择用于乳制品制造的发酵剂或辅助培养物。表型和47株生化鉴定透露十岁的存在乳酸乳球菌，十一植物乳杆菌，三短乳杆菌，双副干酪乳杆菌，十一肠球菌属，七个乳球菌属。和两个乳酸菌属 我们的菌株显示出快速酸化能力（6 小时后 ΔpH 范围在 0.69 ± 0.01 和 1.22 ± 0.05 之间）、高蛋白水解和自溶活性（分别为 1.93 ± 0.02 到 9.9 ± 0.022 mM 甘氨酸和 15.21 ± 2.21%）到 83% ± 2.24% ，以及重要的脂肪分解和自由基清除能力。此外，它们能够利用柠檬酸盐产生胞外多糖，并且它们对革兰氏阴性和革兰氏阳性病原菌表现出抗菌活性并且没有溶血活性。这项研究表明，摩洛哥骆驼奶代表了乳制品行业有趣的 LAB 的丰富生物群落。
