Isolation of microorganisms which
produce CTGases, especially those that are capable of
predominantly producing a particular type of CD, can
reduce subsequent purification costs and is therefore
commercially desirable. Purification of b-CD is easier and
cheaper than purification of a- and g-CD. Consequently,
β-CD has numerous possibilities of application in the
pharmaceutical, cosmetic and food industries, particularly
due to stability of its inclusion complexes. The aim of the
present study was to isolate novel CGTase-producing
alkalopilic bacteria from soil samples of different origin
with emphasis on the ability to preferentially produce
b-CD from starch.
