Furfiirylthiol is a key flavour especially for coffee, beef and roast-like food aromas. It was synthesised in concentrations of up to 1 g L using /1-lyase activity of whole bacterial cells, e.g. Enterobacter cloacae or Eubacterium limosum [256] (Scheme 23.21). Resting cells were used to cleave the sulfur-carbon bond of a furfural-cysteine conjugate and an XAD-4 resin connected to the gas outlet...

Carbon-sulfur lyase, present in Eubacterium limosum cell-free extracts, can liberate volatile long-chain polyfunctional thiols, such as 4-MMP and 3-MH, from -cysteine conjugates. Gene knock-out and expression studies in yeast support the role of carbon-sulfur lyases (Tominaga et al. 1995 Howell et al. 2005 Swiegers et al. 2007). 

Altered Aromatic Metabolites. Loss of parent compound is insufficient evidence to support the occurrence of biodegradation. Frequently, the disappearance of the parent aromatic compound results in the formation of an altered aromatic metabolite. This product indicates that, although biotransformation has taken place, biodegradation has not. An example is the anaerobic O-demethylation of chlorinated guaiacols to chlorocatechols mediated by the acetogenic bacteria, Acetobacterium woodii and Eubacterium limosum (37).
