(2019): Spotlight on biodiversity of microbial cell factories for glycerol conversion
BIOTECHNOL ADV. 2019; 37(6-7), 107395 FullText FullText_BOKU

Plant oil based industrial oleochemistry leads to a large side stream of crude glycerol, which offers itself as a low price carbon source for microbial chemical production. Compared to sugar, glycerol is more reduced and less microorganisms are able to use it as carbon source. An interesting feature of glycerol conversion is that many organisms cannot use it as carbon source at all, but they readily use it as electron sink under anaerobic conditions. In any case the number of pathways by which glycerol enters the microbial metabolism is quite limited. Having said this, an interesting variety of products of industrial relevance is accumulated by naturally occurring microorganisms which can use glycerol. These chemicals range from fuels and solvents to polymer precursors up to food additives. The limited number of metabolic pathways and the manageable amount of products allow to highlight the importance of tapping the outstanding resource of biodiversity for industrial purposes. The interplay of microbial biodiversity, metabolic engineering and bioprocess engineering is key for economic success in industrial microbiology. In this article we shed light on the biodiversity of naturally glycerol consuming microorganisms and their impact and importance on microbial chemical production.
