THE UTILIZATION OF MICRO-ORGANISMS IN A PRACTICAL HANDBOOK ON FERMENTATION AND FERMENTATIVE PROCESSES FOR THE USE BY DR. FRANZ LAFAR, Professor of Fermentation-Physiology and Bacteriology in the With an Introduction by DR. EMIL CHR. HANSEN, Principal of the Carlsberg Laboratory, Copenhagen. DR. LAFAR has paid me the compliment of forwarding me a copy of the first volume of his TECHNICAL MYCOLOGY," with a request that I should write a preface to the work. A perusal of the book gives me the impression that its contents will in themselves be a sufficient recommendation, and ensure the success of the work through its own inherent value; consequently, an Introduction by me is so far superfluous. Should, however, a few words of mine be the means of helping to secure for the work of my young colleague a readier introduction, here and there, than it would perhaps otherwise find, I shall be exceedingly pleased. The First Volume treats of BACTERIA. In a series of chapters we are shown the predominant rôles-both useful and antagonistic-played by these organisms in Distilling and Brewing; in the preparation of Wines and the manufacture of Vinegar; in the Dairy; in Farming; in the preparation of Agricultural Fodder; and in the manufacture of Tobacco and of Sugar. Then follows an account of the relation of Bacteria to sundry transformations occurring in Nature, particularly the important facts recently established in connection with the combination of free nitrogen by bacterial agency, with the iron and sulphur bacteria and the bacteria of nitrification. It might be feared that, in a work aiming at objects so decidedly practical, the theoretical side of the subject would possibly be overlooked. This is, however, not the case in the present instance, as a glance at the Table of Contents will suffice to show. V 41801 |
