- ... Heat stress inhibits photosynthesis by reducing the activation of Rubisco by Rubisco activase. To determine if loss of activase function is caused by protein denaturation, the thermal stability of activase was examined in vitro and in vivo and compared with the stabilities of two other soluble chloroplast proteins. Isolated activase exhibited a temperature optimum for ATP hydrolysis of 44 degrees ...

- ... Acetate-degrading anaerobic microorganisms in freshwater sediment were quantified by the most probable number technique. From the highest dilutions a methanogenic, a sulfate-reducing, and a nitrate-reducing microorganism were isolated with acetate as substrate. The methanogen (culture AMPB-Zg) was non-motile and rod-shaped with blunted ends (0.5–1 μm × 3–4 μm long). Doubling times with acetate at ...

- ... The supercontraction of various types of wool, modified wool, and other keratins has been studied using concentrated solutions of lithium salts, particularly the bromide. The purity of the lithium bromide has been found to be of considerable importance, traces of bromine in the solution having a profound effect. With bromine concentrations in the range 10⁻⁴-10⁻⁵ M, marked differences between clean ...
