Determination of biologically active B-vitamins: utilizing bacteria to close the gap

Microbiological methods for vitamin determination have been established over the past 30 years in the area of food analysis but the traditional technique is time-consuming and the handling cumbersome. A novel method has emerged which applies the old principle of microbiological analytics – determining biologically active vitamins through bacterial growth – to a miniaturised and optimised process. The ID-Vit® technology determines B-vitamins turbidimetrically in human or animal samples using simple microtiter plate assays. This microbiological method has the exceptional advantage of specifying only vitamin compounds which can be metabolized by bacteria and are therefore physiologically relevant.
