What are the organism used for making soy sauce?

Here's how the process works:

1. Soybeans and wheat are cooked and mixed with *Aspergillus oryzae* spores. The mold grows on the mixture, breaking down the starches and proteins.

2. Salt is added to the mixture, and the whole thing is fermented in large tanks for months. This process is crucial for developing the characteristic flavor of soy sauce.

3. The fermented mixture is then pressed to extract the liquid, which is soy sauce.

So, the organism responsible for making soy sauce is *Aspergillus oryzae*, a mold that plays a vital role in the fermentation process.
