| 摘要 |
The present invention provides microorganisms, in which the activity of 4-hydroxybenzoate polyprenyltransferase or 2-octaprenylphenol->2-octaprenyl-6-methoxyphenol flavin reductase is reduced or lost, and which have an ability to produce lactic acid, in particular, microorganisms comprising a chromosomal DNA in which a gene encoding a protein having 4-hydroxybenzoate polyprenyltransferase activity or a protein having 2-octaprenylphenol->2-octaprenyl-6-methoxyphenol flavin reductase activity is partially or completely defective; and a process for producing lactic acid using the microorganisms.
