Table 4

Effect of agitation speed on pectinase production.

Agitation (rpm)	Enzyme Units (U/ml)	Relative Activity ()
0	7.2 ± 0.4	55.0
120	13.1 ± 1.8	100.0
150	11.7 ± 1.2	89.3
180	11.1 ± 0.6	84.7

(i) Values are mean ± S.D. of 3 replicates.
(ii) Values followed by different superscripts are significantly different at (P<0.05).
(iii) Values followed by same superscripts are not significantly different at (P<0.05).
