Abstract

The pretreatment of alperujo ended with extracting 4.9% residual olive oil. The
crude fib er, total carbohydrate and oil content were decreased in fungal treated
samples by 36, 62 and 96%, respectively. On the other hand, an increase in ash and
protein contents was noticeable recording 153.2% and 47.6%, respectively, while
there was no change in phenol content
The enzyme activity of xylanase and CMCase reached its maximum activity at
30 QC after 5 days recording 2.12 and 2.45 IU/ml, respectively. The maximum
activity of both enzymes produced at 55 ”C recording 1.13 and 3.40 IU/ml for
xylanase and CMCase, respectively, showing they are thermophlilic.
The maximum specific activities of xylanase and CMCase (2.53 and 3.22
ID/m I , respectively) was obtained when alperujo( AL) was only soaked in distilled
water for 18hrs. The alkali pretreated alperujo followed by acid was the best
pretreatment trial to produce protein (20.7mg protein per g waste) and monomer
sugars as xylose (26.5Ilmol per g waste), and glucose (51.7Ilmol per g waste) when
fungus grown on the pretreated waste with no additives.
Alperujo methanol and ethanol extracts have highest antagonistic effect against E.
carotovora subsp. carotovora at 20.25AU and 17.36AU, respectively. Second in order
was R. solanacearum, which was antagonized with both extracts at 13.44AU, followed
by E. arnylovora that was also affected with both extracts at 2.78AU.
