FIG 6.

mRNA expression levels of genes encoding nitrile-converting enzymes in V. boronicumulans CGMCC 4969. CK (control), CGMCC 4969 cultured in LB medium; CoCl₂, V. boronicumulans CGMCC 4969 cultured in LB medium supplemented with 0.1 mmol · liter⁻¹ CoCl₂; IAN, V. boronicumulans CGMCC 4969 cultured in LB medium supplemented with 100 mg · liter⁻¹ IAN. “6 h” and “12 h” indicate the sampling times of V. boronicumulans CGMCC 4969. Error bars represent the standard deviations from three biological replicates.
