Adaptive Mechanisms and Substrate Interactions of Microbial Communities in Dry Extremes Live Sciences Microbiology
Abstract
Major Goals: The objective of this project was to elucidate microbe-mineral interactions in rock-inhabiting microbial communities and how these interactions impact the assembly, adaptations, and activities of these communities in extreme environments. We used a coordinated technical approach of materials science and biology to unravel the physical and chemical mechanisms that underpin the adaptations of these microorganisms. The work we accomplished can be summarized in three main areas: (1) identify key cellular networks linked to survival and sense-and-respond mechanisms of endolithic microbial communities from extreme environments, (2) determine at the physical and chemical levels key interactions between microorganisms and their rock environment for water extraction from gypsum rock, and (3) for magnetite dissolution and iron acquisition by cyanobacteria in extreme environments. ARO's mission is to provide basic research in engineering, physical, information and life sciences, developing and exploiting innovative advances to insure the Nations technological superiority. Our findings provide valuable insights for uncovering the evolved design strategies used by microorganisms to maintain their viability in the face of multiple environmental challenges. The findings may help researchers develop practical applications such as material synthesis, power generation, strategies for advanced water storage methods, and engineered living material under harsh environmental conditions, potentially enabling tactical advantages for DOD related functions Accomplishments: 1. Identify key cellular networks linked to survival, sense-and-respond mechanisms to perturbation, and interactions between community members and with the rock substrate.
