Microbial Production of Pyrroloquinoline Quinone

open access: yesAgricultural and Biological Chemistry, 1984
The possibility of preparing pyrroloquinoline quinone (PQQ), a novel coenzyme, by a microbial method was proposed for the first time. PQQwas formed and accumulated in the culture mediumof various microorganisms. Of the tested strains, somemethylotrophs were most favorable for PQQ production and more than 10μg/ml ofPQQ was found in the culture ...

Levels of pyrroloquinoline quinone in various foods [PDF]

open access: yesBiochemical Journal, 1995
The levels of free pyrroloquinoline quinone (PQQ) in various foods were examined by the use of gas chromatography-mass spectrometry. PQQ was extracted from the samples, after addition of [U-13C]PQQ as internal standard, with n-butanol and Sep-Pak C18 cartridges.

Production and Radioprotective Effects of Pyrroloquinoline Quinone [PDF]

open access: yesInternational Journal of Molecular Sciences, 2011
Pyrroloquinoline quinone (PQQ) was produced by fermentation of the Methylovorus sp. MP688 strain and purified by ion-exchange chromatography, crystallization and recrystallization. The yield of PQQ reached approximately 125 mg/L and highly pure PQQ was obtained.
