Bacterial metabolism of methylated amines and identification of novel methylotrophs in Movile Cave [PDF]

, 2015
Movile Cave, Romania, is an unusual underground ecosystem that has been sealed off from the outside world for several million years and is sustained by non-phototrophic carbon fixation. Methane and sulfur-oxidising bacteria are the main primary producers,
