The ecological dynamics of secreted bacteriocins and the evolution of multiple bacteriocin production in Escherichia coli

细菌产生的化合物被称为细菌素，对其他微生物有毒。细菌作为生物防治剂和用于控制微生物病原体的益生菌制剂的成功，部分是由于细菌素。细菌素也可以作为传统抗生素的替代品和天然食品防腐剂。细菌素作为生物防治剂的活性剂、抗生素替代品、食品防腐剂以及益生菌制剂特性的一部分的潜在用途，需要对细菌素的生态进化动力学有充分的了解。了解细菌素的生态学和进化是拟议研究的目标。

Bacteria produce compounds known as bacteriocins that are toxic to other microorganisms. The success of bacteria as bio-control agents and in probiotic formulations for the control microbial pathogens is, in part, due to bacteriocins. Bacteriocins may also have a role as replacements for traditional antibiotics and as natural food preservatives. The potential usefulness of bacteriocins as the active agent in bio-control agents, as antibiotic replacements, as food preservatives, and as part of the repertoire of traits in probiotic formulations requires a sound understanding of the eco-evolutionary dynamics of bacteriocins. Understanding the ecology and evolution of bacteriocins is the goal of the proposed research.
