  • Production in Escherichia coli of extracellular Serratia spp. hydrolases
    Patent number: 5173418
    Abstract: Extracellular Serratia spp. enzymes have been found to be excreted by another gram-negative organism harbouring a plasmid carrying DNA from Serratia spp. encoding the enzymes. This organism, e.g. E. coli, is therefore employed to produce the enzymes, specific examples of Serratia spp. enzymes produced are a nuclease, a lipase and a phosopholipase. The nuclease may be employed to remove nucleic acids from a biological material.
