In that respect, the substrate concentrations offered to the cells were orders of magnitude too high compared with what these cells may experience in the million-year-old sediment in which they subsist. The novelty is the test of whether the deeply buried organisms maintain the potential to metabolize and grow, i.e., whether they are still alive and physiologically intact. Morono et al. (3) show that most, and perhaps all, of the cells are indeed alive. As many as 76% of the cells assimilated isotope-labeled substrate such as glucose or amino acids, some more than 1,000 times faster than the mean rates of organic carbon assimilation that are typical for the deep biosphere.<br /><br />Why is this result so important? Is it really so hard to determine whether microorganisms are alive and active? To appreciate the challenge of the new study, it is necessary to envision life at an energy flux many orders of magnitude lower than anything studied in bacterial cultures in the laboratory so far. Deep subsurface sediments have ages of many millions of years. However, they are inhabited by highly diverse communities of microorganisms with densities of 103 to 108 cells/cm3 (1, 4). These microorganisms have as their main food the remains of organic material that sank out of the paleo-ocean in the geological past, became buried deep down into the seabed, and has been slowly degraded ever since at steadily decreasing rates. It is truly surprising that sufficient organic material still remains for the organisms to feed on and for the large microbial communities to be maintained.<br /><br />The explanation is that <b>deep life is able to proceed in extreme slow motion</b></i>."
