Temperature inhibition of siderophore production in Azospirillum brasilense.
The effect of growth at 42 degrees C on the different components of the siderophore-mediated iron transport that are induced by iron limitation in Azospirillum brasilense was examined. Biosynthesis of the siderophore spirilobactin was strongly inhibited (20-fold) by growth at 42 degrees C, whereas the transport of iron by the ferric-spirilobactin transport system and the induction of the iron-regulated outer membrane proteins were unaffected.
