چکیده

Lactobacilli are well reckoned for their technological and probiotic significance and their exercise in dairy products for trade and industry. The present study was carried out to isolate and characterize Lactobacilli from various dairy and non dairy sources of Indian origin. The isolates were subjected to phenotypic and genotypic characterizations followed by partial 16S rDNAsequencing . As many as 40 isolates were identified as Lactobacilli and among them 14 were identified as L.plantarum, 5 as L. fermentum, 5 as L. delbrueckii subsp. bulgaricus, 4 L. brevis , 2 L. pentosus and 1 isolate as L. mucosae. The great diversity was found with the place as well as source of collection.

Phenotypic and genotypic diversity of dominant lactic acid bacteria isolated from traditional yoghurts produced by tribes of Iran

Morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (LAB), isolated from traditional yoghurts produced by tribes of Iran. From 60 yoghurt samples, a total of 137 LAB isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. Biochemical tests showed the occurrence of 9.76% mesophilic ho...
