After coling this sugar solution, the author added some ammonium sulphate, ammonium phosphate, magnesium chloride, and kalium chloride etc. as the yeast neutrients and inoculated a small quantity of yaest. But this medium did not ferment. Then, the author has analysed this sugar solution. The results were as follows : grams in 100cc.furfural…0.062 methyl furfura' and hydroxymethyl furfural…0.014 essential oils…0.019 formic acid…0.018 acetic acid…0.052 pentose…1.049 total sugar…2.525
