I have isolated bacterial colonies on pikovskaya agar plate but when transferring them to nutrient agar plate as well as nutrient broth for purification they were not growing

You can try adding 0.5 up to 3 g/L of "yeast extract" to the nutrient agar/broth.
thank you Elhussein Fouad Mourad I will also try this one..........
may be chemical composition
