Selection of robust starters from household dahi and assessment of their sensitivity to bacteriophage isolated from dairy effluents
Identifying the predominant strains of lactic acid bacteria (LAB) in dahi that are resistant to bacteriophages is essential for developing robust starter cultures. Dahi samples from two agroecological zones of Kerala were collected for isolation of LAB. Limosilactobacillus fermentum emerged as the dominant starter culture species based on sequence-based identification and technological property characterisation. Dairy effluents were screened for phages targeting L. fermentum, and 10 of 11 strains of L. fermentum showed resistance to one lytic phage isolated as part of this study. The strain ADMT 15 showed sensitivity to the phage and on subsequent genome sequencing the phage revealed its close relationship to members of the Herelleviridae phage family.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
