THE EFFECT OF CYCLODEXTRIN ON THE DESTRUCTION OF PHENOL BY BACTERIA PSEUDOMONAS STUTZERI AND PAENIBACILLUS MACERANS IN THE AQUATIC ENVIRONMENT
Autor: E.A. Gilvanova, P.Yu. Milman
Publikováno v: ÈKOBIOTEH. 4:203-209
Cyclodextrins (CD) by their chemical nature are typical "host molecules" that can encapsulate a wide range of molecules, one or two benzene rings, including a phenolic ring. CDs can affect the bioavailability of contaminants during biodegradation, as
