Short-term effects of amoxicillin on bacterial communities in manured soil.

abstract：:A clone (LP001) expressing a new lipase gene was isolated from a metagenomic library of the Brazilian Atlantic Forest soil. The DNA insert of LP001 was fully sequenced, and 38 ORFs were identified. Comparison of ORFs, %G + C content and gene organization with sequenced bacterial genomes suggested that the fosmid DNA i...
