发明名称 Method for microbial production of cyclic adenosine 3′, 5′-monophosphate
摘要 The invention relates to a method for the production of adenosine 3′,5′-monophosphate (cAMP) by a permeable microbial strain which uses polyols for protecting activities of enzymes and a cAMP precursor and phosphate as substrates. Glucose is used as an energy provider and metal ions and an organic solvent such as acetone are used in the medium.
