Abstract
Dry mouldy bran (DMB) containing gibberellic acid (GA,) is a solid fermented material resulting from solid state fermentation by Gibberellufqjikuroi P-3. Samples of this bran were subjected to supercritical fluid extraction (SCFE) to remove other concomitant products which are produced during the fermentation process. A fungal sterol, identified as the major component in the extract, was found to disturb the defensive mechanism in rice seedlings. The physicochexnical and spectral characteristics of this sterol were established. The extraction of the sterol by SCFE was found to improve with the use of an entrainer (ethanol). The fungal mycelia and spores were disintegrated during the SCFE process. The solid material retained the GA, activity without any loss during extraction and can be used directly for application on agricultural fields.
