enzymes used in the above processes the glucose rich syrup can be further treated with glucose isomerase to obtain a fructose rich syrup the fructose rich syrup can be used as a sweetener in beverages baked or canned foods and dairy products other monosaccharides can also be obtained by treating the glucose rich syrup or the fructose rich syrup with a microorganism see e g lin et al u s pat no 6 455 301 and ojamo et al u s pat no 6 602 691 alternatively the glucose rich syrup can be treated with a microorganism to obtain a fermentation product such as wine vinegar lactic acid citric acid or amino acids for example the glucose rich syrup prepared from rice can be used to produce rice wine directly or can also be mixed with grapes to facilitate the production of red wine to produce amino acids one or more nitrogen sources should be present in the glucose rich syrup for example one can add urea to the glucose rich syrup 1 glutamic acid can be produced from glucose using the bacteria brevibacterium divaricatum nov sp see e g su et al bulletin of the association of agricultural chemical society of japan 1960 24 2.
