Table 4.

Vanillin yield obtained at 30°C from different E. coli cell line and cloning vector.

Wild type	Strain		Vector	*Vanillin yield^ (mM)**
	Parental	Derivate
E. coli K12	JM109	JM109(pBB1)	Replicative	2.31 ± 0.21^a
		FR13	Integrative	3.51 ± 0.14^b
	DH5α	FR14	Integrative	2.42 ± 0.09^a
E. coli B	CGCS	FR12	Integrative	1.61 ± 0.04^c

Values calculated after 24 h of bioconversion. The superscript letters indicate similarities or significant differences between the values. Values with no letter in common significantly differ at p ≤ 0.05 (Tukey HSD test).
