Kinetic data are needed to develop basic understanding of fermentation processes and to permit rational design of continuous fermentation processes. The kinetics of the fermentation of glucose to lactic acid have been studied at six constant pH levels between 4. 5 and 6.0 by measuring the instantaneous rates of bacterial growth and of lactic acid formation throughout each fermentation. It was f...

Xylitol is an extracellular sugar alcohol produced by the biological conversion of xylose through the fermentation process. The present study investigates the reaction kinetics of xylitol fermentation by considering the effect of substrate and product concentration on the microbial growth rate. A 3.5-L batch fermentation produced xylitol at different xylose concentrations and agitation speeds. ...

The very important problems concerning fermentation kinetics have only recently received some attention (Calam et al., 1951; Gaden, 1955a, b, 1956; Borzani, 1957; Kosin, 1957). In the particular case of continuous alcoholic fermentation, a great number of papers have been published (Alzola, 1940, 1945; Bilford et al., 1942; Owen, 1948; Asai et al., 1952, 1953; Mariller et al., 1952; Borzani, 19...

The current study aimed to evaluate the variation in fermentation activity along the distal canine gastrointestinal tract (GIT, Exp. 1). It also aimed to assess fermentation kinetics and end product profiles of 16 dietary fibers for dog foods using canine fecal inoculum (Exp. 2). For Exp. 1, digesta were collected from the distal ileum, proximal colon, transverse colon, and rectum of 3 adult do...

the effect of eucalyptus (eucalyptus globulus labill;egeo) and angelica (heracleum persicum desf. ex fischer; hpeo) essential oils was assessed at the levels of 0, 3, 30, 300 or 3000 (µl 30 ml-1) on in vitro fermentation of buffered rumen fluid from 3 castrated male sheep. the fermentation kinetics were estimated after 54 hours incubation. the fermentation kinetic values, in vitro gas productio...

Thermolyzed casein is known to promote the growth of aberrant crypt foci (ACF) and colon cancer when it is fed to rats that have been initiated with azoxymethane. We speculated that the promotion was a consequence of increased colonic protein fermentation (i.e., that the thermolysis of the casein decreases its digestibility, increases the amount of protein reaching the colon, and increases colo...
