Let
f,
g be two germs of holomorphic functions on
Cn such that
f is smooth at the origin and (
f,
g) defines an analytic complete intersection (
Z, 0) of codimension two. We study Bernstein polynomials of
f associated with sections of the local cohomology module with support in
X=
g−1(0), and in particular some sections of its minimal extension. When (
X, 0) and (
Z, 0) have an isolated singularity, this may be reduced to the study of a minimal polynomial of an endomorphism on a finite dimensional vector space. As an application, we give an effective algorithm to compute those Bernstein polynomials when
f is a coordinate and
g is non-degenerate with respect to its Newton boundary.
