<p><b>(A)</b>. Restriction analysis of total DNA from <i>B. animalis</i> subsp. <i>lactis</i> CNCM I-2494. Lane1, molecular weight marker X (Roche). Lane 2: Unrestricted total DNA from <i>B. animalis</i> subsp. <i>lactis</i> CNCM I-2494, Lane 3–5 total <i>B. animalis</i> subsp. <i>lactis</i> CNCM I-2494 DNA restricted with lane 3, HindIII; lane 4, AvaII and lane 5, EcoRI. <b>(B)</b> Restriction analysis of plasmid DNA isolated from three representative <i>E. coli</i> Xl1Blue -pWSK29-M.BanLII. Plasmid DNA from <i>E. coli</i> Xl1Blue -pWSK29-M.BanLII restricted with PstI and XbaI, lanes 2–4 (expected and obtained, product sizes of PstI +XbaI digests are 5420 bp and 1605 bp), or AvaII, lanes 5–7.</p>
