Lactobacillus crispatus strain UMNLC2 Lcrispatus9C4S15195

Lactobacillus crispatus strain UMNLC2 (Lcrispatus9C4S15195) is a Gram-positive, rod-shaped bacterium that typically arranges itself in chains. As a facultative anaerobe, it can thrive in both oxygen-rich and low-oxygen environments, making it versatile in different habitats. This strain is categorized as mesophilic, with an optimal growth temperature of 37°C, which is relevant for many of its host species. Lcrispatus9C4S15195 is non-motile and does not possess flagella, which suggests that its movement is limited to passive diffusion within its environment. This bacterium is free-living, indicating that it does not rely on a host for survival, although it has been associated with several hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), Aves (birds), and Olea europaea (olive trees). This wide host range may suggest ecological versatility and a potential role in various microbiomes. The strain has a single replicon and one membrane, hallmark traits of many Lactobacillus species that contribute to their stability and resilience in diverse environments. The presence of L. crispatus in both animal and plant hosts suggests its potential significance in food fermentation processes and gut health in animals, particularly humans. The ability of this strain to inhabit various biological niches highlights its ecological importance and potential applications in probiotics and agriculture.
