Abstract:

Three endophytic Muscodor isolates isolated from needle tissues of the critically threatened Abies beshanzuensis can produce intense volatiles in vitro, which in general cause obvious inhibition or even death to a wide range of plant pathogens, indicating their strong antibiotic activity. In this paper, the fungal agents derived from solid-state fermentation were applied to efficiently control the fruit postharvest diseases, including Botrytis cinerea, Physalospora pyricola and Monilinia fructicola. The SPME-GC-MS technique was used to detect the volatile profiling of Mucodor, and the result showed that there were obvious difference in the chemical components and relative content among the three Mucodor isolates. Muscodor sp. M25 had relatively simple chemical composition of volatiles, while Muscodor fengyangensis M112-2 and M153 had complicated composition. The difference in their chemical composition of volatiles was, to some degree, correlated with their bioactivity. Propanoic acid, 2-methyl-, propanoic acid, 2-methyl-, methyl ester and β-phellandrene were the main volatile small molecules. Thus, those Muscodor isolates would be ideal candidates to be exploited as novel ‘myco-fumigation’ agents.
