Developments in Food Microbiology―4

There is no doubt that this volume, like its predecessors, contains some outstanding reviews of topics of immediate relevance to food microbiolo­ gists. Current views on botulism or the detection of mycotoxins are obvious examples, while the authoritative discussion of culture systems for the dairy industry will be widely welcomed by those concerned in any way with the fermentation of milk. The theme of fermentation is explored further with respect to the use of immobilised enzymes, as is its potential role in the disposal of wastes from the food processing industries. A timely plea that biologists should adopt a more imaginative approach to food fermentations provides an apposite conclusion. For as microbiologists become increasingly involved with the minutiae of the subject, so it becomes all too easy to overlook the basic patterns of behaviour that can be observed in natural ecosystems. Yet to ignore this fund of knowledge could, in the long term, prove to be an omission of fundamental significance. In conclusion, I would like to acknowledge, with gratitude, the diligence and cooperation of the contributors, as well as the enthusiastic support of the publisher, for it is their efforts that have made this volume into such an attractive source of information for students of food microbiology.
