*Linear identities in graph algebras *

Comment.Math.Univ.Carolin. 50,1 (2009) 11-24. **Abstract:**We find the basis of all linear identities which are true in the variety of entropic graph algebras. We apply it to describe the lattice of all subvarieties of power entropic graph algebras.

**Keywords:** graph algebra, linear identity, entropic algebra, equational basis, lattice of subvarieties, power algebra of subsets
