This nitrogen recovery method is for causing nitrifying bacteria to decompose an ammonia component in an ammonia-containing gas, and recovering a nitrogen component contained in ammonia as an ammonia gas decomposition product, involving: supplying circulating water to a microorganism decomposition tank retaining a nitrifying bacterium carrier carrying nitrifying bacteria to maintain the carrier wet; passing ammonia-containing gas through the carrier in the wet state in an oxygen-containing atmosphere; dissolving an ammonia component in the ammonia-containing gas in the circulating water, together with an ammonia gas decomposition product produced by the nitrifying bacteria, to continue decomposing the ammonia-containing gas while the decomposition product is accumulated in the circulating water; and collecting all or a portion of the circulating water to recover the ammonia gas decomposition product, when the concentration of nitrate ion as an ammonia decomposition product in the circulating water reaches a predetermined concentration of 5000 mg/L or more.

Provided herein are methods for purifying recombinant A Disintegrin-like and Metallopeptidase with Thrombospondin Type 1 Motif 13 (ADAMTS13) protein from a sample. The method comprises enriching for ADAMTS13 protein by chromatographically contacting the sample with hydroxyapatite under conditions that allow ADAMTS13 protein to appear in the eluate or supernatant from the hydroxylapatite. The methods may further comprise tandem chromatography with a mixed mode cation exchange/hydrophobic interaction resin that binds ADAMTS13 protein. Additional optional steps involve ultrafiltration/diafiltration, anion exchange chromatography, cation exchange chromatography, and viral inactivation. Also provided herein are methods for inactivating virus contaminants in protein samples, where the protein is immobilized on a support. Also provided herein are compositions of ADAMTS13 prepared according to said methods.

Disclosed herein are methods specifically tailored for facilitating the mitigation of cosmetic impressions associated with fingerprint impressions on surface(s) of articles of manufacture made from anodized substrates. To this end, such methods provide for removal of fingerprints by enzymatically functionalizing the surface(s) of the article of manufacture (e.g., a cosmetic coating thereof) to generate an enzymatically active surface and activating such enzymatically functionalized surface(s) to promote such fingerprint removal. Thus methods and articles of manufacture made in accordance with such methods provide improved end-use utility and functionality of many products for consumer electronic applications, automotive applications, building materials applications, and the like.
