Abstract excerpt
BACKGROUND: In bioengineering, growth of microorganisms is limited because of environmental and industrial stresses during fermentation. This study aimed to construct a nisin-producing chassis Lactococcus lactis strain with genome-streamlined, low metabolic burden, and multi-stress tolerance characteristics. RESULTS: The Cre-loxP recombination system was applied to reduce the genome and obtain the target chassis...
