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 that typically arranges itself in chains. This strain exhibits facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic environments. It has an optimal growth temperature of 42.0°C, suggesting a preference for warmer conditions that may be encountered in specific habitats. L. delbrueckii subsp. delbrueckii is primarily found in a variety of natural environments, indicating its versatile ecological adaptability. This species is known for its role in the fermentation processes of dairy products, where it contributes to the production of lactic acid. The ability to ferment sugars under varying oxygen levels enhances its utility in diverse fermentation contexts, making it a key player in food microbiology. The ecological significance of L. delbrueckii subsp. delbrueckii extends beyond food production, as its presence in multiple habitats suggests a potential role in maintaining microbial balance and influencing the dynamics of microbial communities. This adaptability underscores the importance of Lactobacillus species in both industrial applications and natural ecosystems, highlighting their contribution to biogeochemical cycles and microbial interactions.
