Colonies arising from plate cultures of strain MITXM-61 with lignocellulose-derived inhibitors. The bacterial cells were plated onto defined agar media containing 16 g L⁻¹ glucose supplemented with 2.5, 5.0 and 7.5 g L⁻¹ of lignin, 0.25, 0.5, and 0.75 g L⁻¹ of 4-HB, or 0.5, 1.0 and 1.5 g L⁻¹ of syringaldehyde, and incubated for 14 days.
