Penicillin G Degradation Rate
• Penicillin degradation is a first order reaction
• After 50 hours of stressing, 40g/L remains
• After 90 hours of stressing, 40g/L remains due to higher degradation rate

Startup1. Activate electrical system 2. Activate fire and water systems 3. Activate natural gas/
instrument 4. Fill Cooling-water system and
circulate 5. Activate air and steam systems6. Turn on boiler7. Start air compressors8. Start feed to the biodigestor9. Sterilize media using steam10. Start up one fermenter train at
a time
Shut Down1. Remove hazardous process
materials2. Reroute streams to
designated area3. Turn heat and coolant off4. De-pressure the systems 5. Isolate the systems from other
processes 6. If shut down prolongs, protect
the equipment from deteriorating
No significant deviation from the standard procedure
