High expression of the penicillin G acylase gene (pac) from Bacillus megaterium UN1 in its own pac minus mutant

Abstract
By marker exchange mutagenesis, Bacillus megaterium strain UN‐1 (Bm‐UN1) was used to prepare a mutant strain B. megaterium UN‐cat (Bm‐UNcat) lacking the penicillin G acylase gene (pac). The pac gene ...
