The invention relates to a method for the production of adenosine 3',5&#x2032;-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.

Method for microbial production of cyclic adenosine 3', 5&#x2032;-monophosphate

The present invention providesand an application thereof. A preservation number of theprovided in the invention is CGMCC No. 5234. Theprovided in the present invention can be used for cogeneration of acetone, butanol, ethanol, and 3-hydroxy butanone through fermentation, so as to improve the economic benefit of butanol fermentation. NAD+ coupling and regeneration can be implemented by adding metabolism or growth regulating substances, so as to improve the product yield, and at the same time, the yield of cogeneration products can be flexibly adjusted, so as to cater for the market demand.

Clostridium acetobutylicum and application thereof

The present invention provides a method for desorbing and regenerating a butanol-adsorbing hydrophobic macroporous polymer adsorbent, comprising: successively eluting the hydrophobic macroporous polymer adsorbent with butanol adsorbed therein using a water soluble low-boiling-point polar solvent and water. The method provided in the present invention has a simple process, a short separation time, easy, fast and complete desorption and regeneration, low equipment investment and pollution, and reduced energy consumption, and therefore production is easy on a large scale.

Method for desorbing and regenerating butanol-adsorbing hydrophobic macroporous polymer adsorbent

Disclosed is a method for separating butanol. The method uses hydrophobic macroporous polymer adsorbent to separate butanol in a mixed solution, and the process comprises the following steps: 1) using macroporous polymer adsorbent to adsorb butanol in a mixed solution; 2) desorbing butanol from macroporous polymer adsorbent. The method is simple; the separation time is short; the efficiency of butanol recovery is high; and the separating cost is low.
