Lactobacillus delbrueckii subsp. bulgaricus strain ND04

Lactobacillus delbrueckii subsp. bulgaricus strain ND04 is a gram-positive bacterium characterized by its rod shape and the formation of chains. This strain is a facultative anaerobe, indicating that it can grow in both the presence and absence of oxygen. L. delbrueckii subsp. bulgaricus ND04 is non-motile and does not possess flagella, which is typical for many members of the Lactobacillus genus. The optimal growth temperature for this strain is 42°C, within a mesophilic temperature range, which suggests a preference for moderate heat conditions, often encountered in its natural habitats. L. delbrueckii subsp. bulgaricus ND04 is known to be free-living and has been associated with Homo sapiens, indicating its presence in human-related environments, likely as part of the gut microbiota or in fermented dairy products. The strain has a single replicon and a single membrane structure, typical of many bacteria in this genus. Its accession number is NZ_CP016393.1, which refers to its genetic information available in public databases. From an ecological perspective, L. delbrueckii subsp. bulgaricus ND04 plays a significant role in fermentation processes, particularly in yogurt production, contributing to the flavor and texture of dairy products. Its ability to thrive at elevated temperatures highlights its adaptation to specific niches in human-associated environments, underscoring its importance in both microbiology and food science.
