Growth Of Phytophthora Infestans Race 1.2.4 And Synthesis Of Steroid Glycoalkaloids By The Fungus In Synthetic Media, Melanie R. Maas
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A chemically defined synthetic medium was developed in which Phytophthora infestans (Mont.) de Bary race 1.2.4 grew extensively. This medium consisted of: 90.0 grams maltose, 20.0 grams DL-alanine, 20.0 grams L-proline, 1.0 gram KNO3, 0.5 gram KH2PO4, 0.25 gram MgSO4. 7H2O, 1.0 milligram thiamin per liter of distilled water. The average level of growth in this medium was 0.5864 gram dry weight mycelium per 50 milliliters medium.
The glycoalkaloids, solanidine and solanine, were synthesized by Phytophthora infestans in the above medium with 62.5 percent of the samples positive and an overall …
