| titleOfInvention | Method for concentrating compound bacterial fermentation broth for gel breaking enzymes by ultrafiltration membrane separation technology |
| abstract | The invention discloses a method for concentrating fermentation broth for fermenting and producing biological gel breaking enzymes by compound bacteria, and provides a method for concentrating and fermenting acquired compound biological gel breaking enzyme liquid by an ultrafiltration membrane separation technology. The method has the advantages that by selecting proper filter membranes and ultrafiltration conditions for performing ultrafiltration and concentration for fermentation broth, a synergistic effect of alpha-galactosidase and beta-mannase in a gel breaking procedure is perfectly kept for concentrated biological gel breaking enzyme liquid, both the stability and the gel breaking performance of the concentrated biological gel breaking enzyme liquid are greatly improved, concentrated compound biological gel breaking crude enzyme liquid can be directly used in a water-based fracturing process, the cost for breaking guar gum by a biological enzyme method is greatly reduced, and the method has a good application prospect in a fracturing and gel breaking process in the petroleum industry. |
