Biotechnology of riboflavin

Applied Microbiology and Biotechnology, 2016
Riboflavin (vitamin B2) production has shifted from chemical synthesis to exclusive biotechnological synthesis in less than 15 years. The underlying extraordinary achievement in metabolic engineering and bioprocess engineering is reviewed in this article with regard to the two most important industrial producers Bacillus subtilis and Ashbya gossypii ...

Production of Vitamin B2 (Riboflavin) by Microorganisms: An Overview

Frontiers in Bioengineering and Biotechnology, 2020
Riboflavin is a crucial micronutrient that is a precursor to coenzymes flavin mononucleotide and flavin adenine dinucleotide, and it is required for biochemical reactions in all living cells.

Riboflavin intake and status and relationship to anemia.

Nutrition reviews, 2022
Riboflavin in its coenzyme forms, flavin mononucleotide and flavin adenine dinucleotide, is essential for multiple redox reactions necessary for energy production, antioxidant protection, and metabolism of other B vitamins, such as niacin, pyridoxine ...

Riboflavin in Milk [PDF]

Nature, 1956
SUCH studies as have been made on the riboflavin in milk point to the existence of species differences in respect of the forms in which this vitamin occurs in milk. Thus Kon and Mawson1 reported that the concentration of riboflavin in human milk is very low, and found that the method of Emmerie2, in which riboflavin is extracted by methanol was ...

An update on the genetics, clinical presentation, and pathomechanisms of human riboflavin transporter deficiency

Journal of Inherited Metabolic Disease, 2019
Riboflavin transporter deficiency (RTD) is a rare neurological condition that encompasses the Brown‐Vialetto‐Van Laere and Fazio‐Londe syndromes since the discovery of pathogenic mutations in the SLC52A2 and SLC52A3 genes that encode human riboflavin ...

Riboflavin analogs and inhibitors of riboflavin biosynthesis

Applied Microbiology and Biotechnology, 2006
Flavins are active components of many enzymes. In most cases, riboflavin (vitamin B(2)) as a coenzyme represents the catalytic part of the holoenzyme. Riboflavin is an amphiphatic molecule and allows a large variety of different interactions with the enzyme itself and also with the substrate.

The chemiluminescence of riboflavin

Archives of Biochemistry and Biophysics, 1953
Abstract 1. 1. It has been found that the oxidation of riboflavin with peroxide produces light of approximately the same color as the fluorescence of riboflavin. 2. 2. Data concerning the temperature dependence of the reaction have been presented. 3. 3. Optimal luminescence without added metallic activators occurs around pH 7–8. 4. 4.

Photochemistry of riboflavin

Experientia, 1962
Le spectre d'absorption, les caracteristiques luminescentes et photochimiques de la riboflavine sont presentes. L'interpretation des donnees experimentales d'autres auteurs sur la decomposition photochimique de l'eau sensibilisee par la riboflavine est critiquee.
