Physiological, proteomic, and whole-genome transcriptional responses of Nitrosomonas europaea to heavy metals (Zn²⁺,Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide : identification of heavy metals and cyanide stress response genes

Creator:

Park, Sunhwa

Abstract:

Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...

Quorum sensing gene regulation in Pseudomonas aeruginosa

Creator:

Gupta, Rashmi

Abstract:

Pseudomonas aeruginosa is an opportunistic human pathogen that infects immunocompromised individuals such as those suffering from burns or the genetic disorder cystic fibrosis. This organism utilizes a cell-cell communication mechanism known as quorum sensing (QS) to coordinate virulence gene expression and biofilm formation. It has three interconnected QS systems, namely...
