| titleOfInvention | Penicillin fermentation broth treating technology |
| abstract | The invention discloses a penicillin fermentation broth treating technology, which comprises the following steps of: cooling an original penicillin fermentation broth, filtering the cooled penicillin fermentation broth by a closed ceramic-membrane cross-flow filtration system, and collecting high-titer ceramic-membrane filtrate; during filtration, when the wet solid content in the penicillin fermentation broth is enhanced to 1.8-2 times that of the original fermentation broth, adding water with weight accounting for 2 times that of the original fermentation broth for dialyzing to obtain and collect low-titer ceramic-membrane filtrate, and then nano-filtering, concentrating and dewatering the low-titer ceramic-membrane filtrate for later use; continuing to add water with weight accounting for 2 times that of the original fermentation broth for dialyzing to obtain and collect ultra-low-titer ceramic-membrane filtrate; stopping filtration until the titer of penicillin in the penicillin fermentation broth is low to 500-800U; collecting bacterium dregs intercepted by the ceramic-membrane filtration system; putting the high-titer ceramic-membrane filtrate in 6APA (6-aminopenicillanic acid) for conversion or oxidization, ring enlargement and cracking, thus preparing 7-ADCA (7-aminodeacetoxy cephalosporanic acid); and collecting the obtained bacterium dregs and adding engineering bacteria for decomposing the bacterium dregs. |
