	<span style="line-height:1.5;">In this paper, we discuss the equation of state for
nonlinear spinor gases in the context of cosmology. The mean energy momentum
tensor is similar to that of the prefect fluid, but an additional function of
state </span><i style="line-height:1.5;">W</i><span style="line-height:1.5;"> is introduced to describe the
nonlinear potential. The equation of state w(a)^-1 in the early
universe is calculated, which provides a natural explanation for the negative
pressure of dark matter and dark energy. </span><i style="line-height:1.5;">W</i><span style="line-height:1.5;"> may be also the main origin of the cosmological constant L. So the nonlinear spinor gases may be a candidate
for dark matter and dark energy.</span>
