Abstract:
A process for making a detergent powder containing a surfactant-extracted enzyme, the process comprising:a) extracting the enzyme as a paste or liquid from a clarified or whole fermentation broth comprising the desired enzyme byi) contacting the broth with one or more salts and a suitable surfactant having a hydrophile-lipophile balance of at least about 12, wherein said salt has a monovalent or divalent metal cation and a halide or polar oxygenated anion;ii) separating the fermentation broth into two phases, a first surfactant-rich phase, and a second salt-rich phase; andiii) recovering the first surfactant-rich phase comprising the desired enzyme;b) agglomerating the extract with a suitable detergent paste mixture to produce an enzyme containing agglomerate; andc) drying the enzyme containing agglomerate to obtain said detergent powder.
