Catabolite repression allows bacteria to adapt quickly to a
preferred (rapidly metabolisable) carbon and energy source
first. This is usually achieved through inhibition of
synthesis of enzymes involved in catabolism of carbon
sources other than the preferred one

Catabolite repression is an important part of global control 
system of various bacteria and other micro-organisms. 
Catabolite repression allows bacteria to adapt quickly to a 
preferred (rapidly metabolisable) carbon and energy source.It 
is otherwise called as Carbon catabolic repression. This is 
usually achieved through inhibition of synthesis of enzymes 
involved in catabolism of carbon sources other than the 
preferred one. The catabolite repression was first shown to be 
intiated by glucose and therefore sometimes referred to as the 
glucose effec
