Aerobic cultures of S. alluvius in Wickerham's yeast-nitrogen-base medium with starch as sole carbon source become strongly acidic and contain no detectable extra-cellular amylolytic activity during stationary phase, when the activity in buffered cul

We define secretion as the passage from the cytoplasm, across the cell membrane, to the periplasmic space. By contrast, export is the passage across the cell wall into the medium. Operationally we distinguish the two processes by comparing the molecu

Isolated yeast (Saccharomyces cerevisiae) mitochondria incorporate radioactive precursors into mitochondrial DNA. This in vitro labelled DNA was characterized by isopycnic and sedimentation velocity centrifugation both in the native and denatured sta

The dimensions of unfixed rat liver mitochondria, isolated in 0.44 M sucrose, were measured on photomicrographs taken by phase-contrast microscopy. The lengths ranged from the limit of resolution of the microscope (ca. 0.2 μ) to ca. 5 μ. The smalle

When washed cream was frozen slowly and thawed, some breaking of the emulsion occurred and on centrifugation a pellet, mostly membrane material, was obtained. Xanthine oxidase and alkaline phosphatase were present in this pellet, but little enzyme ac

Suspensions of rat-liver mitochondria in 0.44 M sucrose, after they were frozen and thawed under defined conditions, were partitioned into three sedimentable and one supernatant fraction by differential centrifugation. These were analyzed for optical

Processes are described for the controlled treatment of wheat germ with steam or with ethylene dichloride vapours followed by steam. The products are highly palatable and have excellent keeping and baking qualities. The improved quality is associated
