Lactiplantibacillus plantarum strain 19.1

Lactiplantibacillus plantarum strain 19.1 is a Gram-positive, rod-shaped bacterium known for its ability to form chains and its classification as a facultative anaerobe. This strain does not exhibit mobility, as it is non-flagellated, and possesses a single membrane along with a single replicon. Optimal growth occurs at a temperature of 25°C, fitting within a mesophilic temperature range. This strain is characterized by its free-living biotic relationship and has been identified in a variety of habitats. Notably, L. plantarum strain 19.1 has been associated with multiple hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), Lolium multiflorum (Italian ryegrass), Ovis aries (sheep), various Aves (birds), Zea mays subsp. mays (maize), and Medicago sativa (alfalfa). While some strains of Lactiplantibacillus plantarum are well-regarded for their probiotic properties, it is important to note that strain 19.1 has been linked with health effects such as sepsis. This association highlights the complexity of microbial interactions within hosts and suggests that while certain strains may provide beneficial effects, others may pose risks under specific conditions. The presence of L. plantarum in diverse ecosystems indicates its ecological versatility and potential roles in both health and disease dynamics.
