Bulloch's History 01 Bacteriology, published in 1938, is an invaluble account of all the major advances of the nineteenth century and has the advantage of being written be fore biochemistry and genetics had affected ways of thinking about bacteria. Several textbooks of microbiology have brief but interesting introductions; the second editions of Topley and Wilson (1936), Stephenson (1938, 1949), Thimann (1963), Senez (1968), and Stanier et al. (1957) contained the most interesting comments of those consulted.

CLARKE 18 energy sourees. Winogradsky now identified mieroorganisms that existed by oxidizing inorganic compounds and assimilating carbon dioxide as their carbon source. Studies on autotrophie bacteria were extended and developed in several laboratories, but particularly by Beijerinck who, with Winogradsky, contributed to a new approach to the study of bacteria. Winogradsky, in a paper on the nitrifying organisms, set out very clearly the nature of the autotrophie mode of life: two groups of organisms ....

Clarke and Lilly (1969) discussed the regulation of amidase synthesis during growth in batch and chemostat culture and described the variations in enzyme levels at different growth rates for wild type and regulatory mutants of Pseudomonas aeruginosa. In the next ten years increasing use was made of chemostat culture for studies on enzyme regulation, but the technique supplemented, rather than replaced, the traditional batch growth method. Monod et al. (1952) introduced the concept of the differential rate of enzyme synthesis, plotting enzyme activity as a function of the increase in bacterial growth, and this was rapidly adopted by those studying enzyme adaptation.
