*d-Arginine as the sole carbon (C) source. Cells were grown in minimal medium P with 5 mM NH₄Cl and 10 mM d-arginine.

^†d-Arginine as the sole nitrogen (N) source. Cells were grown in minimal medium P with 20 mM glucose and 5 mM d-arginine.

^‡l-Arginine as the sole carbon and nitrogen (C&N) source, cells were grown in minimal medium P with 20 mM l-arginine.

^§No growth for at least 48 h.
