BACILLUS LICHENIFORMIS MUTANT HOST CELL

摘要

A Bacillus licheniformis mutant host cell comprising a mutation (deletion) in one or more genes encoding polypeptides involved in antibiotic synthesis, wherein the mutant host cell expresses at least 5% less of the one or more polypeptides involved in antibiotic synthesis than the parent host cell, when cultivated under comparable conditions. The mutant host cell is used for producing heterologous polypeptides.
