The correlation between bacteria and fungi in sugarcane tops silage prior to and after aerobic exposure was analyzed. The results showed that the abundance of Lactobacillus increased from 0.03% to 27.84% from d 0-60. Additionally, the abundance of Pichia also increased from 0.003% to 15.46% from d 0-60. Following aerobic exposure, the abundance of Lactobacillus increased by 42.39% at d 3. Moreover, Pichia was the dominant fungal genus after aerobic exposure. Spearman's correlation analysis showed that Pichia was positively correlated with the genera Lactobacillus and Pediococcus, but negatively correlated with the genera Acinetobacter, Citrobacter, and Serratia. Aspergillus, Cladosporium, and Fusarium were positively correlated with the genera Clostridium, Lactobacillus, and Pediococcus, but negatively correlated with the genera Acinetobacter, Citrobacter, and Serratia. Spearman's correlation also suggested that Aspergillus, Cladosporium, and Fusarium could be inhibited by screening Serratia, thereby reducing mycotoxins in silage.
分析了有氧暴露前后甘蔗梢青贮中细菌和真菌的相关性。结果表明，从第 0 天到第 60 天，乳杆菌的丰度从 0.03%增加到 27.84%。此外，毕赤酵母的丰度也从第 0 天到第 60 天从 0.003%增加到 15.46%。有氧暴露后，第 3 天乳杆菌的丰度增加了 42.39%。此外，毕赤酵母是有氧暴露后的主要真菌属。Spearman 相关性分析表明，毕赤酵母与乳杆菌属和肠球菌属呈正相关，与不动杆菌属、柠檬酸杆菌属和沙雷氏菌属呈负相关。曲霉属、枝孢属和镰刀菌属与梭菌属、乳杆菌属和肠球菌属呈正相关，与不动杆菌属、柠檬酸杆菌属和沙雷氏菌属呈负相关。Spearman 相关性还表明，曲霉属、枝孢属和镰刀菌属可以通过筛选沙雷氏菌来抑制，从而减少青贮饲料中的霉菌毒素。
