a business secret the cyclodextrin glucanotransferase, newly isolated strain paenibacillus pabuli us132, producing a large quantity of beta cyclodextrin with anti rassissant retaining the freshness of bread.

摘要

the present invention relates to the screening of a glucanotransfu00e9rase (. beta. - cyclodextrin beta cgtase) secreted by the strain paenibacillus pabuli us132, newly isolated from a tunisian soil, purification and physicochemical characterization of the enzyme.the cloning and identification of the dna sequence and the amino acid of the so-called beta cgtase activity as well as for the activity to produce a significant amount of cyclodextrins (cds) with generation of beta cyclodextrins (beta cd) as my joritaire.we also describe the effect of the use of the cgtase in bread making, for on the one hand, to improve the volume of bread and, on the other hand, to prevent the phenomenon of the rassissement days after cooking.
