Enhancing the aerobic stability of whole-plant corn silage is essential for producing high-quality silage. Our research assessed the effect of inoculation with or and its modulation of the bacterial and fungal microbial community structure in an aerobic stage of whole-plant corn silage. Following treatment with a distilled sterile water control, , and (2 × 10 cfu/g), whole-plant corn was ensiled for 60 days. Samples were taken on days 0, 3, and 7 of aerobic exposure, and the results showed that inoculation with or improved the aerobic stability of silage when compared to the effect of the control ( < 0.05). Inoculation with attenuated the increase in pH value and the decrease in lactic acid in the aerobic stage ( < 0.05), reducing the filamentous fungal counts. On the other hand, inoculation with or increased the diversity of the fungal communities ( < 0.05), complicating the correlation between bacteria or fungi, reducing the relative abundance of and in bacterial communities, and inhibiting the tendency of to replace in fungal communities, thus delaying the aerobic spoilage process. Due to the prevention of the development of aerobic spoilage microorganisms, the silage injected with or exhibited improved aerobic stability.
