Abstract

A process for the production of ethanol (alcohol), which consists of at least a suitable method of culture, one of the simonasmobilis strains with a specific capacity. In the production of ethanol at 30 c, pH 5 and in a medium with 300 g / l of glucose at least 4.0 g / g / h, the rate due to glucose uptake at 30 c PA value. G and in a medium which has at least 200 g / l glucose equal to 8.0 g / g / h and has a ethanol tolerance level of 30, pH 5 and in a medium with 300 g / l of glucose. At least 4 cores equal to 120 g / l of ethanol in periodic culture, or at least equal to 60 g / l of ethanol L in continuous culture at 30 c P-value. H5 and in a lower body containing 150 g / l of glucose:

Claims (1)

Disclaimer (all) which will not appear on the advertisement page: (1) the process for producing ethanol from a medium containing glucose or other fermented carbohydrates that make up At least the microorganisms were cultured in the medium, which one strains of the zymonasmobilis were selected from the group consisting of CP4, ZM 481 mutants of these strains. And mixtures of these And which has a specific capacity to produce ethanol at 30 c, pH 5 and in a medium which has at least 200 g / l of glutose as 4.0 g / g / h. The specific rate of glucose uptake of 30C, pH5 and in a medium containing at least 200 g / l of glucose is 8.0 g / g / h and with a degree of ethanol resistance. At 30C pH5 and in a medium containing at least 300 g / l of glucose, 120 g / l of ethanol in periodic incubation or at 30C PA value. G5 In a medium containing at least 150 g / l of glucose equal to 60 g / l of ethanol in continuous culture. And retrieval of ethanol produced (2) the claim method (1) in which the strains of (Zymonasmobilis) have a specific ability to produce ethanol. At 30 c, pH 5 in a medium containing at least 200 g / l of glucose equal to 5.0 g / g / h (3), according to the claim (1) that the strain of ( Zymonasmobilis has a specific rate of glucose depletion of 30 C, pH 5 and in a medium with at least 200 g / l of glucose equal to 10 g / g / h.
