Characterization of Genes Involved in the Metabolism of α-Galactosides by Lactococcus raffinolactis
Boucher, Isabelle, Vadeboncoeur, Christian, Moineau, Sylvain
Lactococcus raffinolactis, unlike most lactococci, is able to ferment α-galactosides, such as melibiose and raffinose. More than 12 kb of chromosomal DNA from L. raffinolactis ATCC 43920 was...
