- Abstract
The aim of this study was to isolate Aspergillus versicolor and explore the inhibitory effect of Lactobacillus versicolor on Aspergillus versicolor. In vitro oxford cup method was used to adjust the concentration of Aspergillus versicolor spore suspension to 1×105 CFU/mL in three groups: Lactobacillus fermentans group, Lactobacillus reuteri group and mixed Lactobacillus group, adjust the concentration of the resuscitated Lactobacillus fermentum and Lactobacillus reuteri to 1×108 CFU/mL, the mixture of Lactobacillus fermentum and Lactobacillus reuteri was prepared in the proportion of 1:1. The inhibition of the three groups on Aspergillus versicolor was compared by measuring the diameter of inhibition zone. The paper agar diffusion method was used to determine the drug resistance of Aspergillus versicolor to 20 kinds of common drugs. The results were as follows: ① compared with Lactobacillus fermentans, Lactobacillus reuteri and mixed Lactobacillus had better antibacterial effect on Aspergillus versicolor. ② The isolated strains were resistant to ceftriaxone, minocycline, kanamycin, gentamicin, cefradine and ampicil‐ lin, and sensitive to 14 other drugs. This experiment can provide new data for probiotics to inhib‐ it feed mold of livestock and poultry, and provide data reference for treatment of aspergillosis of livestock.
