Abstract

This paper reports the high level expression of the Staphylococcus aureus cat gene in Lactobacillus plantarum using the expression vector pMTL500F. When the recombinant strain of L. plantarum was grown in pure culture, CAT contributed 1.4% of the total soluble cell protein. The recombinant strain of L. plantarum continued to express a high level of CAT when inoculated into silage, the heterologous protein constituting up to 1.75% of the total soluble cell protein. The recombinant L. plantarum strain was still able to survive and proliferate when inoculated into silage, despite its additional metabolic load.
