Cattle Fodder and Human Nutrition With Special Reference to Biological Nitrogen Fixation

Abstract

THE process of nitrogen fixation is at once one of the most intriguing and elusive of the unsolved problems of microbiology. It is apparently brought about only by the living cells of certain bacteria and algæ, and the immediate products of nitrogen fixation are in consequence mixed with those of protein degradation whose presence is inevitable in an active cell. This fact has made it very difficult to determine which nitrogen compounds, found in the cells or in their surroundings, are to be regarded as the early products of fixation.
