---|---|---|
Red pigments | Citrinin | |
Control | 67 | 15 |
2-Pentanone (1.32) | 66 | 9 |
2-Heptanone (1.0) | 70.5 | 7 |
2-Nonanone (0.80) | 62.5 | 2 |
2-Tridecanone (0.57) | 54 | 0 |
Glucose and MSG were each present at a concentration of 5 g · liter−1. While levels of citrinin and pigments were determined throughout growth, only the maximal values are reported. For most of the experiments, the maximum was reached between 130 and 160 h of growth. The data reported are from one typical experiment which was repeated twice with consistent results (standard deviation, about 10%).
