Let M be an exact symplectic manifold with c 1 (M)= 0. Denote by Fuk (M) the Fukaya category of M. We show that the dual space of the bar construction of Fuk (M) has a differential graded noncommutative Poisson structure. As a corollary we get a Lie algebra structure on the cyclic cohomology HC•(Fuk (M)), which is analogous to the ones discovered by Kontsevich in noncommutative symplectic geometry and by Chas and Sullivan in string topology.
