Inoculated substrates were incubated at temperatures 30, 40, 50, 60 and 70ºC for 20 hours
at pH 7.0. Results (Fig. 3) showed that enzyme production could occur on all substrates.
Highest enzyme activity was recorded for potato peel (0.14 Units), while kitchen wastes
supported production over the broadest range of temperatures. As far as temperature was
concerned, highest activity was recorded at 50ºC. Enzyme production on all four substrates
was supported even at 70ºC, while for 30ºC, only one substrate showed enzyme activity.
However, one-way ANOVA (Minitab 2010 version 16.1.1) showed that differences in enzyme
production were not significant (P >.05) with respect to both substrate and temperature.
