چکیده انگلیسی
Biofumigation is a biocontrol method that uses volatile compounds to combat soil pathogens. We investigated a biofumigation process based on the green manure of Brassicaceae. These plants contain the glucosinolate-myrosinase system which releases inhibitory compounds such as isothiocyanate into the soil. However, the biocontrol effectiveness is often lower than expected, possibly due to microbial transformation of the isothiocyanates. In order to identify the possible function of microorganisms, their interaction with glucosinolates and glucosinolate-derived products was investigated. We report the ability of a soil isolate of Aspergillus flavus to grow in liquid culture and convert 2-propenyl and 2-phenylethyl glucosinolate and their desulfo-derivatives, to nitriles. This finding would suggest the existence of an arylsulfatase and a β-thio-glucosidase, different from myrosinase, which could direct glucosinolate conversion in soil towards nitriles rather than isothiocyanates. If confirmed in soil, our observations could at least partially explain the low concentrations of isothiocyanates after biofumigation.
