Typical colony sizes for SCV and prototypic strains (left and right sides of the plates, respectively) for (a) S. aureus CF07-S and CF07-L, (b) S. aureus NewbouldΔhemB and Newbould, (c) B. cereus ATCC 11778 (SCV#1 and prototypic), (d) B. subtilis ATCC 6333 (SCV#2 and prototypic), and (e) L. monocytogenes ATCC 13932 (SCV#1 and prototypic). In (f), a TSA plate was inoculated with L. monocytogenes ATCC 13932 SCV#2 and wells were filled with (i) 10 μg hemin, (ii) 10 μg menadione, (iii) 100 μg thymidine, and diluents (iv) DMSO, and (v) NH4OH 1.4 N. A zone of enhanced growth is observed around (i). The enhanced growth appears white and surrounds a small zone of growth inhibition
