The present invention provides a finings formulation comprising pectin and methods of using pectin in a fining process to produce fined beverages, particularly beers.

Methods and compositions for fining beverages

This invention relates to a method of monitoring a fermentation process. In particular, the invention relates to a method of monitoring a fermentation process comprising the step of measuring the expression level of one or more zinc regulated nucleic acid molecules from a microorganism, preferably selected from the group consisting of, andcells, present in the fermentation and comparing the expression level to a reference level of expression for the nucleic acid molecules, wherein the expression level is indicative of sub-optimal fermentation. Preferably the fermentation process is a beer brewing process.

Method of monitoring a fermentation process

This invention relates to soil conditioner, fertilizer and fungicide compositions. In particular it relates to soil conditioner, fertilizer and fungicide compositions that utilizes by-products from brewing processes, and especially made from malt extract or spent grain liquor. The invention also relates to methods of manufacturing soil conditioners, fertilizer and fungicides.

Malt extract or spent grain liquor based fertilizer

This invention relates to soil conditioner, fertilizer and fungicide compositions. In particular it relates to soil conditioner, fertilizer and fungicide compositions that utilizes by-products from brewing processes, and especially made from malt extract or spent grain liquor. The invention also relates to methods of manufacturing soil conditioners, fertilizers and fungicides.

A method for the simultaneous production of sorbitol and either gluconolactone or gluconate from glucose and fructose. To this end to produce sorbitol and gluconolactone, glucose and fructose are reacted in the presence of a cell or cell-free extract of a bacteria, which contains the enzyme complex glucose/fructose transhydrogenase including the tightly bound co-factor(s), under condition whereby the further metabolism of gluconolactone is substantially prevented. In order to produce sorbitol and gluconate glucose and fructose are reacted in the presence of a cell or cell-free extract of a bacteria which contains an enzyme system comprising the enzyme complex glucose/fructose transhydrogenase including the tightly bound co-factor(s) and the enzyme gluconolactonase. This reaction is carried out under conditions whereby the metabolism of gluconate is substantially prevented. Preferably the bacteria used in this process is of the genus Zymomonas and most preferably of the species Zymomonas mobilis. The enzyme complex referred to as glucose/fructose transhydrogenase including the tightly bound co-factor(s) has been isolated in its pure form.

Method for the production of sorbitol and gluconate

An improved method for the production of ethanol from a fermentable carbohydrates such as glucose, fructose or sucrose using the bacterium Zymomonas mobilis which method involves continuously culturing the bacterium in a culture medium containing the fermentable carbohydrate, continuously drawing off a portion of the culture medium and replacing that portion with fresh culture medium, separating from the removed portion of the culture medium cells of Zymomonas mobilis contained therein and returning those cells to the culture medium and recovering the ethanol contained in the portion of the culture medium from which the cells have been removed. It has been found that this method results in greatly improved ethanol production without the disadvantages which have been found when yeasts are continuously cultured.

Ethanol production in a continuous process with cell recycle

A process for the production of ethanol from a carbohydrate substrate such as glucose comprising culturing a flocculant strain of Zymomonas mobilis such as ATCC 31822, in a semi-batch manner periodically allowing the flocculent cells to settle, removing the ethanol containing supernatant and introducing fresh fermentation medium into the fermentor.

Semibatch ethanol production

A method of producing ethanol (alcohol) comprising culturing in a suitable means a strain of Zymomonas mobilis which has a specific ethanol productivity at 30.degree. C., pH5 and in a medium containing 300 g/l glucose of at least 4.0 g/g/h; a specific rate of glucose uptake at 30.degree. C., pH5 and a medium containing 200 g/l glucose of at least 8.0 g/g/h; and an ethanol tolerance level at 30.degree. C., pH5 and in a medium containing 300 g/l of glucose of at least 120 g/l ethanol in a batch culture or of at least 60 g/l ethanol in a continuous culture at 30.degree. C., pH5 and in a medium containing 150 g/l glucose.
