This research investigated how adding beneficial bacteria (Azotobacter) affects the growth of oyster mushrooms and their ability to break down their food source. The study found that small amounts of these bacteria help mushrooms grow better while preventing harmful molds from growing. This has important implications for mushroom farming. Impacts on everyday life: • Could lead to more efficient and productive mushroom farming methods • May help reduce the use of chemical fertilizers in mushroom cultivation • Could result in more affordable and available mushrooms for consumers • Demonstrates an environmentally friendly approach to crop improvement • Could help reduce agricultural waste by improving substrate utilization
