This research discovered antibacterial enzymes from mushrooms that can help protect crops from harmful bacteria. The scientists isolated special proteins called L-amino acid oxidases (LAOs) from two mushroom species and found they could kill or inhibit the growth of bacteria that cause devastating crop diseases. The findings are significant for agriculture and food security. Impacts on everyday life: • Could lead to new natural crop protection products to replace harmful chemical pesticides • May help reduce crop losses and improve food security globally • Demonstrates the untapped potential of mushrooms as sources of useful compounds • Could reduce food costs by preventing crop diseases • Shows promise for developing environmentally-friendly agricultural solutions
