Hey mate ^_^
The quantum conformal anomaly is not present in string theory if the dimension of space time is fixed to 26 for bosonic string theory and 10 for superstring theory....
In string theory conformal symmetry in the world sheet is necessary for the theory to be consistent, so the trace of the energy momentum tensor vanishes....
If not we don't have string theory at all....
