Studies on Plant Hypertensinase

Many plants contain an enzyme similar in most biological properties to the hypertensinase obtained from blood and some animal tissues, notably kidney and intestinal mucosa. Wheat bran is a rich source of the plant hypertensinase, and from it a potent, non-toxic preparation was made by the use of isoelectric and ammonium sulfate precipitation as the means of purification. Hypertensinase derived ...

Studies on Bacterial Nutrition. v. the Effect of Plant Tissue upon the Growth of Anaerobic Bacilli

In the case of the pneumococcus, a seeding so minute as to cause in dextrose broth a period of bacterial lag extending over 18 hours will amply suffice to induce prompt growth in plain broth to which pieces of sterile unheated potato have been added. The presence of vegetable tissue causes other changes in the configuration of the growth curve. There is a prolongation of both the stationary pha...

Studies in Plant Metabolism. V. the Metabolism of Radioactive 2,4-D in Etiolated Bean Plants.

Radioactive 2,4-dichlorophenoxyacetic acid (2,4-D) has been used to study the translocation and metabolism of this chemical in plants by several workers (1, 2, 3, 4, 10, 11). Holley et al (2) and Holley (3) using carboxyl-Cl4-labeled 2,4-D demonstrated the presence of free 2,4-D and two radioactive water soluble, ether insoluble organic acids in bean plant homogenate. Jaworski and Butts (4), us...
