How to passage bacteria ? - (Aug/22/2015 )

I guess it makes sense to grow the bacteria in liquid form for few hours before plating.

When I referred to journal, it only mentioned to passage the bacteria for 30 times and count the cfu in the agar each passage and compare with control.

I am stucked at how to passage the bacteria (agar to agar).

Best to just email the authors of that paper. What paper is it?

Restreaking will of course not be an option if you really want to count CFUs.
