We study the strangeness production in hot and dense nuclear medium, by
requiring the conservation of the baryon density, electric charge fraction and
zero net strangeness. The hadronic equation of state is investigated by means
of an effective relativistic mean field model, with the inclusion of the full
octet of baryons and kaon mesons. Kaons are considered taking into account of
an effective chemical potential depending on the self-consistent interaction
between baryons. The obtained results are compared with a minimal coupling
scheme, calculated for different values of the anti-kaon optical potential and
with non-interacting kaon particles. In this context, we also consider the
possible onset of the kaon condensation for a wide range of temperatures and
baryon densities.
