<P><B>Abstract</B></P> <P> <I>Clostridium</I> strain AK1 was investigated for its capacity of producing 1,2-propanediol from <SMALL>L</SMALL>-rhamnose but not <SMALL>L</SMALL>-fucose. The maximum yields of 1,2-propanediol from rhamnose was 0.81 mol 1,2-PD/mol <SMALL>L</SMALL>-rhamnose. The influence of different initial substrate concentrations as well as the effect of temperature and pH on 1,2-PD production was investigated.</P> <P><B>Highlights</B></P> <P> <UL> <LI> <I>Clostridium</I> strain AK1 is a stenothermal moderately thermophilic anaerobe. </LI> <LI> The strain produces (<I>S</I>)-1,2-propanediol from <SMALL>L</SMALL>-rhamnose but not <SMALL>L</SMALL>-fucose. </LI> <LI> Maximum yields were 0.81 mol 1,2-PD/mol <SMALL>L</SMALL>-rhamnose (theoretical 1 mol/mol rhamnose). </LI> <LI> End product formation was observed between pH 4.7 and 7.8. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
