a
Photosynthetic bacteria were grown in different growth conditions with and without light exposure.
b
Iron in D. vulgaris and E. cloacae were estimated with the measured iron per total protein of the cells; we used a conversion factor of 0.55 to convert from protein to volatile solids (28).
c
S. oneidensis iron content was converted from nmol Fe/mg protein to μg Fe/g dry weight using 52.8% protein content as measured previously (67).
