A. a selective differential medium
B. a complex medium
C. a differential medium and a complex medium
D. a selective medium
3b)A plant suspension culture was used to study the effect of three types of media on the growth of the culture using batch culture approach. Figure 3.1 shows the growth of the plant suspension cultures using Murashige and Skoog (MS), Gamborg B5 and Vacin and Went media. Comment and conclude on the results obtained. Suggest which is the most suitable medium to maintain the suspension cultures with justification.

- A. 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.
