Résumé :
The purpose of the present paper consists in proposing
and discussing a double probabilistic representation
for a porous media equation in the whole space
perturbed by a multiplicative colored noise.
For almost all random realizations $\omega$, one associates
a stochastic differential equation in law with random coefficients,
driven by an independent Brownian motion.
The key ingredient is a uniqueness lemma for a
linear SPDE of Fokker-Planck type with measurable bounded
(possibly degenerated) random coefficients.
