We found that the strain had cobbled together remaining hits and pieces of the reaction series
that normally make branched-chain amino acids and their corresponding fusel oil components to make this new fusel oil--like higher alcohol, normal butyl alcohol.
The reaction product into which the C[O.sub.2] is converted can be collected easily in the form of methanol in the last step of the reaction series
. Methanol is an important starting material for many chemical syntheses and serves as an alternative fuel and as a raw material for the production of energy in methanol fuel cells.
In an alternative reaction series
, the so-called kynurenine pathway, tryptophan is catabolized to form nicotine amides and the vitamin niacin X11 as end products.
