industrial acceptance, and commercialization of a new industrial gum (xanthan) of cereal grain origin."8 Jeanes continued her studies on the extracellular microbial polysaccharides, leading to a series of papers on their properties, applications, use to the food industry, and other fundamental and practical applications.
Throughout her career and prior to the advent of computers and word processors, Jeanes published seminal reviews of the literature on dextrans. Her final paper published in 1986, well after her official retirement from NRRL, is a review on the "Immunochemical and Related Interactions with Dextrans Reviewed in Terms of Improved Structural Information." In this paper, published in Molecular Immunology, she considers the work from her laboratory and others that had been published over the past thirty years on dextrans. She indicates that the proper interpretation of past and future studies necessitates pointing out previous inadequacies of dextran structural data. She indicates that new techniques can provide a better picture of the structure of many of the dextrans produced by various strains of bacteria, which can lead to a better understanding of the immunochemical interactions.
Dr. Morey Slodki, who worked with her in her later years, has noted that Dr. Jeanes had a terrific analytical mind and was almost always right. He felt that very few people have the insight and foresight about their work that Jeanes had. He believes it was through her leadership that the dextran industry and microbial gum industry developed in the United States. 9
