Cold storage promotes the emergence and proliferation of Janthinobacterium sp. in raw milk biofilms

This study examines the formation of bacterial biofilms during the refrigeration of raw milk, focusing on the ability of psychrotrophic bacteria to adapt and thrive under cold conditions. By cultivating biofilms on stainless steel surfaces at low temperatures and analyzing their microbial diversity using the 16S rRNA gene sequencing, the research sheds light on the mechanisms that allow certain bacteria to dominate in refrigerated environments. These findings are highly relevant to the dairy industry, as they provide insights into microbial behaviors that could affect milk quality and safety during storage and processing. The study underscores the importance of addressing biofilm formation to mitigate spoilage risks and ensure high standards of dairy product hygiene.
