Antibiotics, such as gentamicin, are used in media to prevent growth of susceptible microbes. Is gentamicin media a selective, differential or enrichment media? B. Sorbitol is a sugar alcohol that all Escherichia bacteria can normally ferment into an acidic waste compound. This acidic end product is detected by including a pH indicator in the agar and noticing a color change. The strain of Escherichia that is a common food pathogen, E. coli O157:H7, however can not ferment sorbitol. It will grow similar to other E. coli, but not change the agar color.

They grew bacterial colonies of Salmonella typhimurium in petri dishes labelled A, B and C. The Petri dishes were kept at 36°C for 48 hours, with scientists observing the bacteria every 24 hours. The results for this investigation are below. Petri dish A B с Treatment Was subjected to ionising radiation followed immediately by a dose of antibiotic X An equal amount of antibiotic X was added (as was added to Petri dish A) Was given neither ionising radiation nor antibiotic X After 24 hours Small spots of growth on surface No growth Growth across whole surface After 48 hours (ii) Identify the purpose of petri dish C. Large spots of growth on surface No growth Growth across whole surface (i) Explain the effect of the ionising radiation on the bacteria.
