Table 3 Paradigm strains of LAB. A listing of the most relevant LAB strains, their genome size and year of publication is provided. Moreover, the presence of CRISPR sequences is given with a summary of the reported transformation frequency, varying from very high, high, medium to low, representing 106-108, 104-106, 102-104, 100-102 transformants per ug of DNA, respectively. ND, indicates not determined.
