How to determine the time to put the fermentation tank into fermentation?

**Fermenter Release Time Guidelines**

The release time for fermentation in a fermenter depends on the specific goals of the process, whether it is for bacterial culture or metabolite production.

### **Key Points:**

1. **Bacterial Culture:**

- Release time is determined by the final bacterial concentration.

- The incubation period is adjusted to achieve the desired bacterial count.

2. **Metabolite Production:**

- Release time is based on the peak concentration of the target metabolite.

- The production process is planned around maximizing metabolite yield.

### **Conclusion:**

The release time is flexible and process-dependent, with no fixed schedule. It can vary for the same bacterial strain depending on growth conditions and requirements.
