production of furfuryl alcohol and 3-methyl-1-butanol by bacillus amyloliquefaciens for postharvest control of fungi

摘要

The present invention includes a process and products for the control of the plant pathogenic fungus botrytis cinerea. volatile furfuryl alcohol and 3-methyl-1-butanol are produced by the bacterium bacillus amyloliquefaciens gf63 in optimized culture medium and both (culture medium and volatiles) are used to control botrytis cinerea. spore germination and mycelial growth of botrytis cinerea are completely inhibited after contact with the volatiles produced by the bacteria and also by chemically purified furfuryl alcohol. Both volatiles and furfuryl alcohol at 1:10 dilution inhibit colonization of b. cinerea in strawberries and other foods and thus increase shelf life by avoiding waste and conserving food by preventing the fungus from spoiling them. The volatiles produced by the bacteria do not persist in food, as the treatment leaves no residue in the strawberries enough to control the fungus and does not alter the product for the final consumer. The volatiles produced by the bacteria also preserve the antioxidant activity of strawberries. The process and products are considered sustainable as they are of biological origin and do not interfere with the environment.
