title: Effects of short-term cold storage on recovery of proteases from extracellular products of Aeromonas hydrophila.
abstract: Three protease-containing fractions were recovered by gel filtration from concentrated crude extracellular products produced by Aeromonas hydrophila grown in a defined medium. The recovery of a heat-stable protease was differentially prevented when the crude preparation was stored for 48 h at -20 degrees C but was unaffected by storage of the crude preparation at either 4 or -70 degrees C. Once fractionated, the heat-stable protease appeared to be unaffected by subsequent storage at 4, -20, or -70 degrees C.
