Table 2. Transformation efficiencies and transposition frequencies.

Sugar	Transformation Efficiency^*	Transposition Events^*
Glucose	8.24×10⁶	1±0.00
GOS	1.47×10⁷	38±14.14
Ribose	1.2×10⁷	198±19.80
Lactose	1.38×10⁷	1554±192.33
Ribose+Lactose	2.19×10⁷	986±123.04

Transformation efficiencies and transposition frequencies were determined following electroporation of a replicative vector, namely pAM5, or a tetracycline-resistant TN5 transposome, respectively, into B. breve UCC2003 competent cells grown in different carbohydrates. Transposition events are average of independent duplicates.
