Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
59 words
Process for the production of ethanol and a protein or peptide which is heterologous to yeast which comprises fermenting an aqueous sugar-containing medium with a yeast strain which has been genetically modified to be capable of expressing a heterologous protein or peptide, recovering the ethanol so formed, and obtaining the said heterologous protein or peptide from the fermentation products.
Claim 2
Dependent Claim
59 words
Process for the production of ethanol and a protein or peptide which is heterologous to yeast which comprises fermenting an aqueous sugar-containing medium with a yeast strain which has been genetically modified to be capable of expressing a heterologous protein or peptide, recovering the ethanol so formed, and obtaining the said heterologous protein or peptide from the fermentation products.
Claim 3
Dependent Claim
47 words
Process according to claim 1 in which the ethanol is recovered in the form of an aqueous potable liquid which is substantially free from yeast and from the said heterologous protein or peptide and which contains substantially all the water and ethanol of the said fermented medium.
Claim 4
Dependent Claim
23 words
Process according to claim 1 in which the ethanol is recovered from the said fermented medium in the form of an ethanolic distillate.
Claim 5
Dependent Claim
18 words
Process according to claim 2 in which the aqueous sugar-containing medium contains maltose as the major sugar present.
Claim 6
Dependent Claim
17 words
Process according to claim 4 in which the aqueous sugar-containing medium is a barley malt-based beer wort.
Claim 7
Dependent Claim
18 words
Process according to claim 2, 4 or 5 in which the fermentation is effected at 8 to 25°C.
Claim 8
Dependent Claim
25 words
Process according to claim 3 in which the aqueous sugar-containing medium is a fermentation medium for the production of potable distilled ethanol or power ethanol.
Claim 9
Dependent Claim
32 words
Process according to claim 7 in which the said medium is based on grain, potatoes, cassava, sugar cane, or sugar beet, optionally pretreated to convert cellulose and/or starch therein into fermentable sugars.
Claim 10
Dependent Claim
19 words
Process according to any one of claims 1 to 8 in which the fermentation is a substantially anaerobic fermentation.
Claim 11
Dependent Claim
30 words
Process according to any one of claims 1 to 9 in which the yeast used is a genetically engineered modification of an industrial strain of Saccharromyces cerevisiae, or S. carlsbergensis.
Claim 12
Dependent Claim
31 words
Process according to any of claims 1 to 10 in which the said heterologous protein or peptide is obtained as protein or peptide retained in the yeast produced during the fermentation.
