BACTERIUM STRAIN PAENIBACILLUS MACERANS AS PRODUCER OF ALPHA-CYCLODEXTRIN GLUCANOTRANSFERASE

摘要

FIELD: biology.;SUBSTANCE: claimed strain provides synthesis of extracellular alpha-cyclodextrin glucanotransferase, forming of alpha-cyclodextrin. Activity of said enzyme in cultural liquid is 43.5 U/cm, wherein activity unit represents amount of cyclodextrin glucanotransferase which catalyzes of 1 muM alpha-cyclodextrin formation for 1 min from 3 % starch solution at pH 6.0 and 40°C. Part of alpha-cyclodextrin and other cyclic products is 74.7 %.;EFFECT: improved producer of alpha-cyclodextrin glucanotransferase.;3 tbl, 2 ex
