MILK ACID SUPRESSOR MUTANTS AND THEIR USE AS SELECTIVE MARKETS AND AS MEASURES IN MILK ACID BACTERIES

摘要

Useful mutants of lactic acid bacteria or plasmids capable of replicating in lactic acid bacteria, comprising nonsense mutation suppressor-encoding genes, the use of such suppressor genes for confining a replicon to a specific lactic acid bacterium or to a lactic acid bacterium growing in a particular environment and for controlling the number of lactic acid bacterial cells in a particular environment.
