Influence of nitrogen source
During evaluation of various compounds as
suitability of nitrogen source, it was found that
urea was the best suited for siderophore production
by S-11. Complex nitrogen source such as soy
flour did not show any siderophore production.
This may be due to very high iron content of soy
flour. Urea as a nitrogen source has additional
benefit of the possible exploitation of the isolates
for the bioremediation of soils by reducing the
amount or urea present in the soil.
