Anaerobic microbial communities and their potential for bioenergy production in heavily biodegraded petroleum reservoirs.

abstract：:Antibiotics are routinely used in modern livestock farming. The manure from medicated animals is used for the fertilization of arable crops, which in turn leads to the accumulation of antibiotic resistance genes (ARGs) in the environment. This is a potentially serious public health issue, yet the identities of the bac...
