There are various fermentation methods for amino acid water-soluble fertilizers. Below are some common approaches:

1. Natural Fermentation Method: Mix amino acid raw materials with an appropriate amount of water and allow them to ferment naturally in a well-ventilated, light-protected environment. This method requires a long duration, typically taking several months to over a year to complete.

2. Yeast Fermentation Method: After mixing amino acid raw materials with water, add yeast for fermentation. Yeast decomposes amino acids, producing multiple metabolic products, including vitamins, minerals, and others. This process usually takes several days to a week.

3. Bacterial Fermentation Method: Mix amino acid raw materials with water and introduce specific bacteria for fermentation. These bacteria break down amino acids, generating metabolic products such as vitamins and minerals. The duration is typically several days to a week.

4. Microbial Fermentation Method: Combine amino acid raw materials with water and use specific microorganisms for fermentation. These microbes decompose amino acids, yielding metabolic products like vitamins and minerals. This method generally spans several days to weeks.

5. Enzyme-Catalyzed Fermentation Method: Mix amino acid raw materials with water and add specific enzymes to drive fermentation. These enzymes catalyze amino acid breakdown, producing metabolic products including vitamins and minerals. The process usually lasts several days to a week.

6. Ion Exchange Method: Combine amino acid raw materials with water and pass them through ion exchange resins for fermentation. This method leverages the resin’s ion exchange capacity to extract ions from amino acids for further reactions. It typically requires several days to weeks.

7. Biofilm Fermentation Method: Mix amino acid raw materials with water and incorporate specific biofilms for fermentation. These biofilms adsorb amino acids and facilitate decomposition reactions on their surfaces. The process usually takes several days to weeks.

8. Bioimmobilization Fermentation Method: Combine amino acid raw materials with water and immobilize them on specific carriers using bioimmobilization technology. This method utilizes functional groups or moieties on the carriers to enhance amino acid decomposition. The duration is typically several days to weeks.

9. Ultrasound-Assisted Fermentation Method: Mix amino acid raw materials with water and treat them with an ultrasound generator. Ultrasound disrupts cell walls, accelerating amino acid decomposition. This process takes minutes to half an hour.

10. Microwave-Assisted Fermentation Method: Combine amino acid raw materials with water and expose them to microwave energy. Microwaves increase temperature and energy density, promoting amino acid breakdown. This method typically requires minutes to half an hour.

numerous fermentation methods exist for amino acid water-soluble fertilizers, each with unique advantages and applicable scenarios. When selecting the appropriate method, production conditions and specific requirements should be carefully considered.
