Printed in Great Britain On the theory of control of microbial growth kinetics by limiting nutrient concentrations D. K. BUTTON* (Received 4 November 1977 ; accepted 2 February 1978 ; linal revision received 2 June 1978) Abstract Some formulations relating nutrient concentration to nutrient transport and to nutrient-limited growth rate are derived. In LaMer burst nucleation, the individual nucleation events happen en masse, quasi-simultaneously, and at nearly identical homogeneous conditions. These properties make LaMer burst nucleation important for applications that require monodispersed particles and also for theoretical analyses. Sugimoto and co-workers predicted that the number of nuclei generated during a LaMer burst depends only

Growth of Thiobacillus ferrooxidans in batch culture on 10 mM potassium tetrathionate was optimal at pH 2.5 (specific growth rate, 0.092 h-1). Oxygen electrode studies on resting cell suspensions showed that the apparent Km for tetrathionate oxidation (0.13 to 8.33 mM) was pH dependent, suggesting
