Antibacterial and preservative effects of different solvents in the extract of Dictyophora indusiata
In order to further explore the antibacterial and preservative effects of Dictyophora indusiata,four differ-ent solvents(ethyl acetate,anhydrous ethanol,petroleum ether and distilled water)were used to extract the fruiting body of Dictyophora indusiata.The antibacterial test was carried out by plate antibacterial test,and the antibacterial effect of food was verified by broth and steamed bread.The results showed that the extracts of Dictyophora indusiata with four sol-vents had obvious inhibitory effect on Salmonella,Staphylococcus aureus and Yeast.Among them,ethyl acetate extract of Dictyophora indusiata had the best antibacterial effect on mold,Staphylococcus aureus,Escherichia coli,Yeast and Sal-monella,and had the most obvious antibacterial effect on mold.The dilution test of ethyl acetate extract of Dictyophora indusiata showed that it still had inhibitory effect after being diluted 4 times.The empirical test of anti-corrosion of steamed bread and broth showed that the ethyl acetate extract of Dictyophora indusiata had anti-corrosion effect on both,especially in meat anti-corrosion.It provides a theoretical basis for the development of natural antibacterial sub-stances from Dictyophora indusiata.
