Abstract

The composition of beet molasses was modified by 14 pretreatment processes which were the combination of physical, physicochemical, and chemical processes, i.e. acid hydrolysis of sucrose, precipitation of metal ions, removal of organic acids by ion exchange resins, and entrapment of metal ions in solution. Acid hydrolysis was favourable for glutamic acid fermentation, while the use of diluted and centrifuged molasses was advantageous for alkaline protease fermentation.
