B. Bacitracin: inhibits the formation of peptidoglycan of Gram positive bacteria
C. Colistin: targets bacterial endotoxin

Bacillus subtilis and Bacillus cereus most likely showed greater resistance to UV light than Serratia marcescens. This is due to:
a. Bacillus spp. are Gram-positive, while Serratia marcescens is Gram-negative
b. the Bacillus spp. are spore fonners
c. the pigment of Serratia marcescens absorbs more radiation than other cells
d. Bacillus spp. have enzymes that protect them from ozone
