Abstract

Highlights: From d 6 to d 60 of ensilage, the abundance of Lactobacillus sharply increased. After aerobic exposure, Ascomycota was the only phylum observed. Pichia was the dominant fungi after aerobic exposure. Pichia was positively correlated with Lactobacillus, Clostridium and Pediococcus. Clostridium was positively correlated with Aspergillus, Fusarium and Candida. Abstract: 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.
