Results documented in (Table 4) showed that, all the tested strains produced the enzyme on all the substrates but with dif-ferent activities. Among the six different solid substrates, artichoke leaves were found to be the most suitable substrate for SSF by A. ter-reus giving maximum inulinase production of 4.433 ± 0.121 U/gds, greater than that obtained with K. marxianus NRRL 7571(positive control) on the same waste. Other substrates were found to be poor inducers for inulinase production by A. terreus. Significant amount of inulinase was also produced on SSF of orange rinds and sugar cane bagasse with A. versicolor and A. parasiticus, respectively. P. brevicompactum showed the highest production with artichoke leaves, banana leaves and sugar cane bagasse than the other substrates.
