The invention relates to a process for the removal of contaminants from a liquor, the process comprising: introducing a metal or ammonium hydroxide into the liquor; introducing the liquor into a reaction vessel; bubbling a carbon dioxide gas comprising at least 25% carbon dioxide through the liquor within the reaction vessel; and separating the precipitate formed by the carbonation of the metal hydroxide from the liquor, the precipitate comprising at least some of the contaminants from the liquor; wherein, on average, the liquor is resident within the reaction vessel for a period of no more than about 60 minutes. The invention also relates to a process for the removal of contaminants from a liquor, the process comprising: introducing a metal or ammonium hydroxide into the liquor and bubbling a carbon dioxide gas comprising at least 25% carbon dioxide through the liquor to fom1 a precipitate by carbonation in a period of no more than about 60 minutes. The carbonation processes may be included in sugar refining or water softening and/or decontamination processes. A use of a carbon dioxide gas comprising at least 25% carbon dioxide in a carbonation process for removing contaminants from a hydroxide-treated liquor is also provided, wherein the process forms a precipitate in period of no more than about 60 minutes.

The present application discloses a method for carbonation with CO.sub.2. The method now disclosed describes the use of a static or dynamic mixer to react the CO.sub.2 with the incoming of nation liquor to whom Ca(OH).sub.2 was previously added and readily starts the precipitation of tiny carbonate crystals. This solution can be advantageously used to compensate the deficit of CO.sub.2 in the carbonation process. This method for carbonation can be applied for example in the sugar refining industry.

A sugar beet extract (SBE) induced defense in potato plants under green-house conditions and in field trial, without apparent toxicity for the plant. Treatment with SBE resulted in significant reduction of the size of Phytophthora infestans infection lesions and lower sporangia production. SBE had no apparent toxic effect, neither on the hyphal growth of the pathogennor on the germination of sporangia. SBE triggered PR-1 protein induction which suggests that the defense mechanism conferred by SBE could be via direct induced resistance. An array of phenolic metabolites and minerals was found in the SBE and constitutes potential inducers of the defense.
