FIELD: biotechnologies.SUBSTANCE: method for simultaneous production of sugar and ethanol includes extraction of a sugar-containing juice from a suitable plant, simultaneous fermentation and treatment of the sugar-containing juice, simultaneous distillation of ethanol and concentration of the sugar-containing juice, crystallisation of the produced concentrate of the sugar-containing juice with production of sugar. Fermentation of the sugar-containing juice is carried out using strains of yeast Saccharomyces or Zygosaccharomyces, not producing a saccharose ferment, or a strain Saccharomyces cerevisiae BY4742 with a damaged gene of saccharase SUC2c, or a strain Saccharomyces cerevisiae Taiken 396 in presence of methyl-?-D-glucopyranoside.EFFECT: conditions of fermentation make it possible to increase share of saccharose in a sugar syrup as a result of consumption in process of fermentation of sugars, which are not saccharose.6 cl, 6 dwg, 5 ex |
