Lactobacillus delbrueckii subsp. delbrueckii DSM 20074 = JCM 1012

Lactobacillus delbrueckii subsp. delbrueckii DSM 20074, also known as JCM 1012, is a Gram-positive rod-shaped bacterium characterized by its chain-like cell arrangement. This species is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, and it does not exhibit mobility due to the absence of flagella. L. delbrueckii subsp. delbrueckii has an optimal growth temperature of 42°C, placing it within the mesophilic temperature range. It possesses a single replicon and a single membrane structure, indicating a relatively simple cellular organization. The bacterium is free-living, suggesting it can thrive independently in various environments. The diverse habitat of L. delbrueckii subsp. delbrueckii underscores its ecological adaptability. Its ability to grow optimally at a higher temperature could reflect its adaptation to specific niches within fermented foods or environments where temperature fluctuations are common. The free-living nature of this bacterium allows it to contribute to microbial communities, potentially playing a role in fermentation processes or influencing the microbial dynamics of its habitats. This adaptability and ecological versatility highlight the importance of Lactobacillus delbrueckii subsp. delbrueckii in various ecosystems, particularly in food production and natural fermentation processes. Accessions such as AZCR00000000.1 provide further research avenues to explore the genetic and functional characteristics of this organism.
