Fermentation Organisms, a Laboratory Handbook

Abstract

THE importance of a systematic study of the microorganisms which play a part in the various processes of fermentation is making itself felt more and more as time goes on and new facts and phenomena are brought to light. The old empirical methods of twenty years ago have passed away before the marvellous changes first introduced by Hansen, and the culture of yeast is recognised as one of the secrets of success in the manufacture of the various kinds of beer. The study has long been carried on under the personal supervision of Hansen and his assistants, but until recently has been almost entirely conducted under some form of personal supervision. As in other cases, however, the study has outgrown so limited a method of teaching, and we have in this volume a laboratory handbook which will enable practical work in the culture of fermentation organisms to be more widely spread, and probably more successfully conducted, than has hitherto been the case. The volume is welcome on this account especially, but it has other claims also on the student, coming as it does from the Carlsberg laboratory, and embodying the ideas and teaching of Hansen himself. It is welcome also to English readers from the fact that it has been translated in great part by one of the disciples of the Burtonon-Trent school, from which have come so many valuable contributions to our knowledge of the chemistry of the carbohydrates concerned in brewing.
