Conjugated Linoleic Acid Production by Bifidobacteria: Screening, Kinetic, and Composition

Table 1

Bifidobacterium strains screened for CLA production, by measuring the absorbance of conjugate diene () after 24 h growth in MRS-LA. indicates species bearing a gene homologue to MCRA from B. breve NCIMB 702258. The 34 strains that were selected for GC quantification of CLA and PCR amplification are underscored.
