Design and preparation of selenized flour: An efficient biomaterial inhibiting the growth of Xoo

Herein, we wish to report a novel method for preparing selenium-containing materials, i.e. the selenization of flour via fermentation. Compared with traditional methods, the fermentation reaction could directly transfer selenium from its inorganic sources into the target material without using any flammable or hazardous chemical reagents. The produced selenized flour could well inhibit the growth of Xoo, the pathogen leading to rice bacterial blight disease. As a selenium-containing material using edible flour as the selenium carrier, it is more biocompatible than many chemical pesticides. Hydroxyls of starch in selenized flour may facilitate the material adhering onto the rice leaves to allow the continuous release of the efficacy.
