arabinose analogues

[David Clarke]

Hi,
I was wondering if anyone out there knows if there exists a 
non-fermentable analogue of L-arabinose (in the same way that IPTG works 
for lactose). Briefly I want to use it to induce expression of a gene 
controlled by the ara promoter whilst at the same time using 
lactose-MacConkey plates to monitor lacZ activity. It would be possible 
to construct a strain that does not ferment arabinose but it would be 
easier for me if there was a non-fermentable analogue.

Thanks in advance

Dave
