Evaluation of the use of leaves extract of soybeans and beans instead of potato extract for fungi media

Abstract

This study aims to evaluate of using of the aqueous extracts of  soybean Glycine max leaves and Phaseolus vulgaris beans in preparing local planting media for the development of some fungi isolated from the soil and seeds of different plants and compared them with the standard PDA, as the isolated fungi were both phenotypically and biologically tested through several tests represented by a test. The decomposition of gelatin, casein, and starch as well as testing the ability of these fungi to represent some carbon sources. Media prepared with the same ingredients in the standard medium other than replacing the potato extract with soy and bean extracts both p for me, the results were as follows: The use of the two prepared mediums of beans and soybeans showed a significant superiority in the growth of fungi compared to the standard medium, as the medium of the beans gave the highest average diameter of the growth of fungi reached 6.62 cm compared to the standard medium which gave the lowest average of 5.76 cm. As for the fungi species, the Fusarium oxysporium fungi was significantly superior to the other species, and gave the highest average growth diameter of 7.00 cm compared to the fungus Aspergillus flavus, which gave an average of 5.48 cm. As for the interference between the type of culture medium used and the type of fungus, the treatment of interference between the medium of beans and the Fusarium oxysporum was significantly superior to other interventions.
