Abstract
Methods are described for the purification and spinning of recombinant and non-recombinant proteins. Specifically, the lysis of bacteria and purification of silk proteins occur in a single solution of organic acid. Bacterial proteins are hydrolyzed while the silk protein remains intact. Silk proteins remain soluble as they are concentrated into a aqueous-based mixture for fiber spinning.
