Book Description
Life on the planet depends on microbial activity. The recycling of carbon, nitrogen, sulphur, oxygen, phosphate and all the other elements that constitute living matter are continuously in flux: microorganisms participate in key steps in these processes and without them life would cease within a few short years. The comparatively recent advent of man-made chemicals has now challenged the environment: where degradation does not occur, accumulation must perforce take place. Surprisingly though, even the most recalcitrant of molecules are gradually broken down and very few materials are truly impervious to microbial attack. Microorganisms, by their rapid growth rates, have the most rapid turn-over of their DNA of all living cells. Consequently they can evolve altered genes and therefore produce novel enzymes for handling "foreign" compounds - the xenobiotics - in a manner not seen with such effect in other organisms. Evolution, with the production of micro-organisms able to degrade molecules hitherto intractable to breakdown, is therefore a continuing event. Now, through the agency of genetic manipulation, it is possible to accelerate this process of natural evolution in a very directed manner. The time-scale before a new microorganism emerges that can utilize a recalcitrant molecule has now been considerably shortened by the application of well-understood genetic principles into microbiology. However, before these principles can be successfully used, it is essential that we understand the mechanism by which molecules are degraded, otherwise we shall not know where best to direct these efforts.

Book Description
Vitamins and related growth factors belong to the few chemicals with a positive appeal to most people; the name evokes health, vitality, fitness, strength . . . . each one of us indeed needs his daily intake of vitamins, which should normally be provided via a balanced and varied diet. However, current food habits or preferences, or food processing and preservation methods do not always assure a sufficient natural daily vitamin supply, even for a healthy human being; this is all the more true for stressed or sick individuals. Although modern society is seldom confronted with the notorious avitaminoses of the past, they do still occur frequently in overpopulated and poverty- and famine-struck regions in many parts of the world. Apart from their in-vivo nutritional-physiological roles as growth factors for man, animals, plants and micro-organisms, vitamin compounds are now being introduced increasingly as food/feed additives, as medical-therapeutical agents, as health-aids, and also as technical aids. Indeed, today an impressive number of processed foods, feeds, cosmetics, pharmaceuticals and chemicals contain extra added vitamins or vitamin-related compounds, and single or multivitamin preparations are commonly taken or prescribed. These reflections do indicate that there is an extra need for vitamin supply, other than that provided from plant and animal food resources. Most added vitamins are indeed now prepared chemically and/or biotechnologically via fermentation/bioconversion processes. Similarly, other related growth factors, provitamins, vitamin-like com pounds, i. e.
