Isolation of the siderophore schizokinen from soil of rice fields

, : Isolation of the siderophore schizokinen from soil of rice fields. Applied and Environmental Microbiology 45(5): 1704-1706

Schizokinen, a siderophore previously isolated from low-iron cultures of Bacillus megaterium and Anabaena sp., was isolated from the soil of rice fields after the annual flooding period.

The effects of soil solution percolated through paddy fields on the growth of rice seedlings (1).. Percolation of water and nutrient solutions under conditions preventing the access of air (sealing by paraffin) had no effect on growth but with air it markedly increased root growth.
