A bacterial culture is treated with streptomycin and a cast is made . A few columns are able to survive due to

Some bacteria are able to grow in streptomycin containing medium due to :

A change in medium composition in a bacterial culture, results into growth of a specific section of that population. This section survived because:

Bauxite ore is made up of Al_(2)O_(3) +SiO_(2) +TiO_(2) +Fe_(2)O_(3) This ore is treated with concentrated NaOH solution at 500 K and 35 bar pressure for few hours and filtered hot. In the filtrate, which species are present?

In a bacterial culture, some of the colonies produced blue colour in the presence of a chromogenic substrate and some did not due to the presence or absence of an insert (rDNA) in the coding sequence of beta - galactosidase. (a) Mention the mechanism and the steps involved in this experiment. (b) How is it advantageous over simultaneous plating on two plates having different antibiotics?
