Evaluation of terminal-restriction fragment length polymorphism analysis in contrasting marine environments.

abstract：:Extreme acidophiles (microorganisms with pH optima of < 3) can colonize and exploit subterranean environments, such as abandoned metal sulfide mines, that have the potential for developing widespread or isolated pockets of acidity. Although acidophiles can utilize a wide range of electron donors, inorganic materials (...
