▎ 摘　　要

NOVELTY - Magnetic bacterial pellet loaded with reduced graphene oxide comprises microsphere structure, which includes reduced graphene oxide-loaded aflatoxin mycelium balls wound around the mycelium ball of Aspergillus mycelium and uniformly sized iron (II,III) oxide magnetic nanoparticles dispersed on the mycelium ball. USE - The material is useful as an adsorbent for the adsorption and removal of heavy metals and/or aflatoxins (claimed). ADVANTAGE - The material has micron-level bacterial pellet structure, has recycling property, and good adsorption performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for synthesizing magnetic bacterial ball material, comprising (i) utilizing filamentous toxin-producing aflatoxin fungal spores as precursors and co-cultivating graphene oxide with them to obtain reduced graphene oxide-loaded aflatoxin fungal balls, and (ii) purifying the reduced graphene oxide-supported Aspergillus flavus spheres are and functionalized, and hydrothermally reacting with the iron precursor.
