Rate Determining Step

An earlier study of the relative rates of degradation of several sucrose derivatives has been refined and extended. The results support a novel hypothesis to explain the unusual alkali-lability of sucrose (1). In this hypothesis the first and rate-determining step in the degradation is an SN1cB displacement effected at the C1 anomeric centre of the glucose moiety by an oxyanion derived from the C1' hydroxyl (10), to produce 1-(α-D-glucopyranosyl)fructose (11). The latter is then very rapidly degraded, mainly to lactic acid. The possibility of analogous competing displacements involving the 3' and 6' oxyanions remains for further investigation.

The study of the growth kinetics of lactobacilli with pronounced probiotic properties in their batch cultivation is essential. Various models based on the logistic curve model, containing parameters showing the influence of the accumulating lactic acid on the biosynthesis of the product, as well as parameters showing the sensitivity of the cells to lactic acid were used to model the growth kinetics in the present work. The rate constant of adaptation of the studied strains to the used nutrient medium and the induction period were also determined. The kinetics of lactic acid synthesis was determined according to the Weibull model.
