Volume 243. Inorganic Microbial Sulfur Metabolism Edited by Harry D. Peck, Jr., and Jean LeGall... 

In 1958, Peck joined the staff of the enzymology group of the Oak Ridge National Laboratory and continued there to work on sulfur metabolism of chemolithoautotrophic bacteria. In 1965, he was called to Athens. Before moving there, he spent a year in the laboratory of Jacques Senez and Jean LeGall. And then he explored the research niche of hydrogenase and sulfur metabolism, which is a gold mine still today, in various directions.

Summary beta-HMX can be prepared by reacting hexamine with ammonium nitrate and nitric acid in the presence of excess glacial acetic acid and acetic anhydride. The rate of additions is crucial to ensure proper HMX formation. After the reaction is complete, the alpha-HMX is refluxed with water to ensure quality and purification. The resulting water insoluble product is then filtered-off, and then recrystallized from acetone to produce excellent crystals of beta-HMX.

Factor F430 is a nickel-containing tetrapyrrole (or hydrocorphinoid) found only in methanogens. It was originally observed by Jean LeGall [2], and purified and partly characterized by Gunsalus and Wolfe [160] as a brightly yellow factor with maximal visible absorbance at 430 nm. It was demonstrated to contain nickel in two independent...

Jean Mayer reviews observations made in families, ethnic groups, and twins which suggested that hereditary factors may predispose an individual to obesity. The weight of natural children correlates well with that of parents, but there is no such correlation between that of adopted children and their legal parents. As in most studies of this kind, it is difficult to distinguish environmental from hereditary factors.
