  We study properties of a class of spin singlet Mott states for arbitrary spin
S bosons on a lattice, with particle number per cite n=S/l+1, where l is a
positive integer. We show that such a singlet Mott state can be mapped to a
bosonic Laughlin wave function on the sphere with a finite number of particles
at filling {\nu}=1/2l. Spin, particle and hole excitations in the Mott state
are discussed, among which the hole excitation can be mapped to the quasi-hole
of the bosonic Laughlin wave function. We show that this singlet Mott state can
be realized in a cold atom system on optical lattice, and can be identified
using Bragg spectroscopy and Stern-Gerlach techniques. This class of singlet
Mott states may be generalized to simulate bosonic Laughlin states with filling
{\nu}=q/2l.
