• 論文の詳細を見る

• Biotin in molasses was remarkably stable to γ-irradiation. The biotin components in cane molasses and in beet molasses were separated respectively into three components (C-1,C-2 and C-3) and two components (B-1 and B-2) by gel-filtration. These components had the same biological activity to Lactobacillus arabinosus as authentic biotin, but were found to differ from authentic biotin in retention volume on gel-filtration and bioautography. The C-1,C-2 and B-2 components were sensitive to irradiation in aqueous solutions. The high stability of these components to irradiation in molasses is therefore considered due to protection by other compounds in molasses.
