  In this paper we generalize the quantization procedure of Toda-mKdV
hierarchies to the case of arbitrary affine (super)algebras. The quantum
analogue of the monodromy matrix, related to the universal R-matrix with the
lower Borel subalgebra represented by the corresponding vertex operators is
introduced. The auxiliary L-operators satisfying RTT-relation are constructed
and the quantum integrability condition is obtained. General approach is
illustrated by means of two important examples.
