Table 2.

Total heme content of the B. clausii strains. The total heme content (heme a + b + c) of the four B. clausii strains at 4.5 and 29 h of growth has been determined as described in Section 2. Reported values are in [(nmol of heme) (mg of total protein)⁻¹]. Reported values are means of three experiments.
