Calcium modulates growth and biofilm formation of Lactobacillus acidophilus ATCC 4356 and Lactiplantibacillus plantarum ATCC 14917.

ABSTRACT: Lactobacillaceae are a large, diverse family of Gram-positive lactic acid-producing bacteria. As gut microbiota residents in many mammals, these bacteria are beneficial for health and frequently used as probiotics. Lactobacillaceae abundance in the gastrointestinal tract has been correlated with gastrointestinal pathologies and infection. Microbiota residents must compete for nutrients, including essential metal ions like calcium, zinc, and iron. Recent animal and human studies have revealed that dietary calcium can positively influence the diversity of the gut microbiota and abundance of intestinal Lactobacillaceae species, but the underlying molecular mechanisms remain poorly understood. Here, we investigated the impacts of calcium on the growth and biofilm formation of two distinct Lact
