We present a perturbative calculation of strange-quark production by the processes {ital g}{r arrow}{ital s}+{ital {bar s}}, {ital g}+{ital g}{r arrow}{ital s}+{ital {bar s}}, and {ital q}+{ital {bar q}}{r arrow}{ital s}+{ital {bar s}} in a quark-gluon plasma containing gluons that are effectively massive'' due to medium effects. We consider only transverse polarizations of the gluons. We find that for a gluon mass beyond 300 MeV the one-gluon decay dominates, and that there is an {ital enhancement} of {ital s{bar s}} production from massive gluons compared with the massless case.
