Description and significance
L. delbrueckii is a gram positive bacteria. It is long, filamentous and non-motile. The environment in which L. delbrueckii thrives the most would be one of relatively low pH. L. delbrueckii and lactobacilli in general undergo homofermtentative metabolism which means they are only able to ferment lactose and no other sugar.
It has complex nutritional requirements, including the inability to ferment any sugar except for lactose. This bacterium is also regarded as aciduric or acidphilic, due to the fact that it requires a relatively low pH (around 5.4-4.6) in order to grow effectively.
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated.
Include a picture or two (with sources) if you can find them.
Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
