Lactobacillus delbrueckii subsp. bulgaricus 2038

Lactobacillus delbrueckii subsp. bulgaricus 2038 is a Gram-positive, rod-shaped bacterium characterized by its chains of cells. It is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. This species is mesophilic, with an optimal growth temperature of 42°C, which indicates a preference for moderate temperatures, typical of environments such as dairy products where it is commonly found. L. delbrueckii subsp. bulgaricus is non-motile, lacking flagella, and exhibits a free-living biotic relationship, signifying that it does not rely on a host for survival. It possesses a single membrane and one replicon, which are typical features of many bacteria. This subspecies is particularly significant in the dairy industry due to its role in yogurt fermentation, where it contributes to the production of lactic acid and other flavor compounds. The ability to thrive at higher temperatures showcases its adaptability to specific ecological niches, especially in environments that favor fermentation processes. The presence of this microorganism in various habitats underscores its ecological versatility, enabling it to play a vital role in microbial communities and food production systems. Its accession number, NC_017469.1, indicates that it has been cataloged in genomic databases, facilitating further research into its genetic characteristics and potential applications in biotechnology.
