Environmental Study Comparison between normal and standard culture media for the growth of fungi

Abstract

The study aims to evaluate the use of rice and starch medium in preparing a culture medium for the development of some fungi isolated from the soil and compare it with standard medium PDA, where the fungi were identified microscopically. The media was prepared with the same components as the standard medium. The results showed that the rice and starch medium were significantly superior in the growth of fungi compared to the standard medium, as the rice and starch medium gave the average growth diameter of Aspergillus niger that reached 4.3-4.6 cm compared with the standard medium PDA which reached 4.1-3.8 cm. It was followed by Alternaria alternate at a rate of 3.6-3.4 cm compared to growth on standard medium 3.3-3.1cm, then Rhizopus stolonifera at a rate of 3.5-3.2 cm compared with growth on standard medium 3.2-3.1 cm, in growth on rice and starch culture medium, while it was less growth of Aspergillus flavus at a rate of 4.3-3.9cm compared with growth rates on the standard culture medium 4.4-4.2 cm.
