Abstract The problem of microbial resistance to antibiotics makes it necessary develop new materials capable overcoming the chemicals currently used. Herein, antibacterial properties modified bamboo powder are tested and compared with cellulose isolated from soybean hulls. Such biomasses functionalized in a water solution (3‐aminopropyl)triethoxysilane introduce primary amino groups, two different functionalization procedures adopted: first requires conventional heating steps, whereas second implies microwave radiation use. main outcomes characterizations evidence that prepared thermal treatment stabler than those obtained by microwave‐assisted procedure bamboo‐derived samples react through functionalities other hydroxyl groups. Finally, activity measured against Escherichia coli Staphylococcus aureus shows all could efficiently remove Gram‐positive Gram‐negative bacteria (removal > 93%). Moreover, active filters realized packing material powders: when bacterial inoculum passes them continuous flow, some differences observed between bamboo‐based materials, but overall performances show after 17 min five recirculation cycles, both reach an excellent removal about 100%.
