chemotrophic bacteria. saprophyte is a term that could describe any organism, not just bacteria.  ""underground septic tank" implies capability to thrive in hostile environments, chemotrophs have this capability.  When classifying bacteria based on mode of obtaining energy, there are 3 choices. 1. Phototrophs(light feeders) 2. Chemotrophs (organic molecule feeders) 3. Chemolitrophs(inorganic molecule feeders)
