From: Chitobiose utilization in Borrelia burgdorferi is dually regulated by RpoD and RpoS
Growth of B. burgdorferi strain B31-A in BSK-II without GlcNAc and yeastolate, and supplemented with 150 μM chitobiose. Late-log phase cells were diluted to 1.0 × 105 cells ml-1 in the appropriate medium (closed circle, 1.5 mM GlcNAc, with Yeastolate; open circle, without GlcNAc, with Yeastolate; open triangle, without GlcNAc, without Yeastolate; closed triangle, without GlcNAc, without Yeastolate, with 150 μM chitobiose), incubated at 33°C, and enumerated daily as described in the Methods. This is a representative experiment that was repeated three times.
