Abstract:

HND5 is an endophytic fungi and had antagonistic activity on varieties of pathogenic fungi, so it had application potential for biocontrol. Sequences analysis of ribosomal DNA and β-tubulin internal transcribed spacer region show HND5 had the highest homologous with Acremonium strictum. Biological characteristics research showed the optimum medium was PDA, the optimum temperature was 28℃, and the optimum pH was 7. The optimum carbon and nitrogen source were cane sugar and NaNO3, respectively. HND5 had the tolerance for potassium dichromate.
