Complex Adaptive Traits (CATs)
Dr. Ilka Bischofs
We focus on studying complex adaptive traits (CATs) in stressed bacteria, employing molecular biology, microscopy, and mathematical modeling. Our goals include understanding, controlling, and engineering these traits. By investigating signaling networks, we aim to uncover fundamental principles linking molecular design to population behavior. Our research, centered on beneficial Bacilli, explores endospore formation, bacterial communication networks, and the production of stress-related metabolites. Ultimately, we seek to manipulate bacterial populations for biotechnological applications, collaborating closely with other research groups.
Research Strategy
The Bischofs group focuses on spore-forming and industrially-relevant Bacilli which use elaborate strategies to adapt to their
environment. These bacteria can diversify phenotypically, which is often undesirable in applications, but could be profitably utilized. We study such complex adaptive traits (CATs) at the behavioral and mechanistic level using systems and synthetic biology methods. We specifically address the function of regulatory networks in the formation and organization of heterogeneous populations. By combining experiments using novel microscopy-based assays and modeling, we have investigated the B. subtilis life cycle and cell-cell communication, respectively. This led to the discovery of a quality-quantity tradeoff during spore formation. Moreover, using B. subtilis as a model organism, we are contributing to studies of stress-associated phenomena with implications for humans and the environment, e.g. ROS-driven methane formation in cells.
