When the transport coefficient based on the mixing length theory, DM, does not include a poloidal mode number, m, it is exactly the same as the scale invariance result, Ds. For the g mode turbulence in stellarators, DM and Ds corresponding to the con-vective and the collisionless stochastic transport coincide with each other. For the rippling mode turbulence in tokamaks, DM includes m and disagrees with Ds as well as the collisional stochastic transport in the g mode case. However, by taking account the scale transformation for the poloidal mode number into the expression of DM, the coincidence is recovered. It is examined how the bootstrap current produced by the electrostatic turbulence changes the transport in the g mode case. A possibility is pointed out that the Kolmogorov spectrum appears in the g mode and the rippling mode turbulence.
