Leveraging adaptive mechanisms and mineral interactions of microbes for lunar extremes
Abstract
Microbes that colonize extreme environments have evolved specific molecular machinery and mechanisms to survive and thrive on their surrounding material substrates. We propose that these mechanisms can be leveraged toward the development of biomining and additive manufacturing processes under extreme conditions, in remote environments. The proposed work plan combines a collection of high throughput techniques to investigate the ability of model organisms to extract high-value minerals on natural (terrestrial and lunar) and synthetic rocky substrates, as well as to screen for microbes with the capacity to thrive in non-native extreme environments (e.g., mining and waste sites). Elements used for energy-based applications (Li, Co, Ni, In, Ga, etc.), catalysis (Pt, Pd, Ru, etc.), structural applications (Si, Al, Mg, Ti, W, etc.), as well as rare earth elements (Nd, Sm, Er, Tb, Y, etc.) will be considered. Microbes will not only be used to extract mineral, but we will leverage their ability to transform the rocky matrix of 3D printed media to form structurally robust, living architected materials. Results and basic science elucidated by this work could not only shed light on how microorganisms survive and metabolize under severe xeric conditions but also could provide insights into potential metabolic activities in even more extreme environments, such as Mars and the Moon. In the long term, we look towards utilizing engineered or adapted biological systems to modify landscapes, extract valuable minerals, and implement them in fabrication processes such as additive manufacturing. It is understood that any developmental items and specially designed parts, components, accessories and attachments generated under this Defense Department agreement are being developed for both civil and military applications.
