The industrial production methods of l-threonine powder mainly include: ① synthesis method; ② fermentation method; ③ protein hydrolysis method. Now advocate the use of fermentation production.
Method 1. Direct fermentation method:
l-threonine powder The fermentation method uses sugar, ammonia and homoserine as the medium, and can be purified by fermentation with glutaminus to obtain L-threonine.
