FAT PRODUCTION FROM CANE MOLASSES BY PENICILLIUM SPINULOSUM: A STUDY ON SUBSTANCES IN CANE MOLASSES INTERFERING WITH FAT PRODUCTION

Abstract

Production of fat by Penicillium spinulosum in cane molasses was poorer than in a defined medium containing sucrose and inorganic salts. The fat content of dry felt obtained in defined medium was 63.8% and the fat coefficient 16.1. In molasses medium the fat content of felt dropped to 24.4% and the fat coefficient to 6.2. Removal of inorganic materials from the molasses increased fat yields substantially, and the addition of molasses ash to the defined medium reduced yields to about the same level as in untreated molasses.
