Acetic acid bacteria encode two levansucrase types of different ecological relationship
Environmental Microbiology, Volume 21, Issue 11, Page 4151-4165, November 2019., 2019 Summary Acetic acid bacteria (AAB) are associated with plants and insects. Determinants for the targeting and occupation of these widely different environments are unknown. However, most of these natural habitats share plant‐derived sucrose, which can be metabolized by some AAB via polyfructose building levansucrases (LS) known to be involved in ...
