Biotechnological production of citric acid

Citric acid was first commercially-produced in England around 1826 from imported Italian lemons (lemons contain 7–9% citric acid). Lemon juice remained the commercial source of citric acid until 1919, when the first industrial process using Aspergillus niger started in Belgium. Currently, the extraction of citric acid is limited to some small factories in Mexico and Africa.
