The pectic enzymes of the fungus Byssochlamys fulva.

It was reported by Beavan & Brown (1949) that cultures of By8aochlamy8 fulva Olliver & Smith produced protopectinase, but neither polygalacturonase nor pectin esterase; they concluded that B. fulva produced a disaggregating enzyme, which lowered the viscosity ofpectin solutions, without the formation of free reducing groups. A re-investigation of the problem has been made, and in a preliminary note (Reid, 1950a), it was suggested that B. fulva produced both polygalacturonase and pectin esterase.
