The production of riboflavin from vegetable oil was increased using a mutant strain of Ashbya gossypii. This mutant was generated by treating the wild-type strain with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). Riboflavin production was 10-fold higher in the mutant compared to the wild-type strain.

Your "MTHFR" Is Just a Riboflavin Deficiency

2019-02-26  It's important to note that endurance exercise, weight loss, high-fat diets, and sunlight exposure all increase your riboflavin requirement substantially. If two or more of these apply to you and you have low MTHFR activity, your riboflavin requirement could be closer to 5 milligrams per day.

2016-04-07  Further was suggested that the transcript levels of mitogen-activated protein kinases, MPK3 and MPK6, were primed under riboflavin. Upon infection by Pst DC3000, these two enzymes were more strongly activated. The elevated activation of both MPK3 and MPK6 was responsible for enhanced defense gene expression and resistance after riboflavin treatment. Moreover, riboflavin
