Hi there
I hope everyone is well
I really need help, I cant find the information I need..

Firstly, I know that crystal violet on filter paper, in the presence of wild type salmonella typhimurium strain creates inhibition around the filter paper, but also bacterial growth after and around the inhibition zone. Is this right?
Im not sure what happens to the bacterial growth when Sodium Deoxycholate is applied, does anyone know?

Furthermore, how do you find out the mutation rate of two given mutagens? i have also tried to such for this, but find this confused :S

Thank you for all your help in advance!!
