✦ Synopsis

Dear sirs,

In Ref. (11, Lin and Wei discuss transient substrate response in a CSTR containing immobilized enzyme particles. It may be of interest to mention a study of the transient response of a batch reactor containing such particles[2-51. This study presented an analytical solution for the special case of first-order reaction and data for the catalase/HzOz system. Data were also presented for the ureaselurea system (Michaelis-Menten kinetics) using the computational algorithm of Shyam[6] for the packed-bed conliguration.

Shvam's studv. like that of Lin and Wei, included Michaelis-h&ken kinetic; &d enzyme denaturation; and also considered the effect of enzyme elution. His study included a thorough analysis of computational procedures and errors, and presented solutions for the oacked-bed cofimuation. It also ,included relaxation of the &ady-state hyp&esis to cover the detailed reaction mte model, Bodenstein intermediates, and Briggs-Haldane kinetics.

There is one practical reason for preferring the batch reactor. The membranes enclosing enzyme solution are, in fact, bags of water, and are easily broken by any but the smallest degree of agitation. They also tend, in fixed-bed configuration, to compress to an impervious mat.
