Abstract
... Respiratory flexibility allows microorganisms to thrive in geologic environments. The ability of anaerobic prokaryotes to employ different terminal electron acceptors for respiration permits these organisms to colonize and populate ecological niches in Earth’s subsurface. One such adaptation is the ...

... We present a model for the study, analysis, design and evaluation of collective multi-agent navigation for autonomous robots based on behaviors observed in bacteria. The system consists of a set of simple agents (artificial bacteria), which through readings and local interaction are self-organized t ...

Saprophytes release digestive enzymes into the organic material around them (e.g. cellulose from trees) and break down the material into nutrient molecules that the bacteria or other organisms can absorb. This process causes the organic material to decay. Explain what ...
