Approach

• Fungal Strain Prescreening

• Inoculation Method

• Bioreactor

• Process design

7Challenge the future

Challenges:

• Limiting bacterial growth and increasing the fungal

growth

• Inoculation strategy in continuous mode

• Maintaining short HRT and long fungal SRT in continues

run with optimum degradation activity
