Evaluating substrate utilisation to target newly identified health-promoting gut bacteria
… microorganisms through the provision of specific substrates has been the subject of many studies over recent decades. Such substrates can include prebiotics, which promote growth in a targeted manner, but prebiotics can also be combined with other less target-specific nutrients to further enhance …

A prototype dynamic model for the co-treatment of a high strength simple-organic industrial effluent and coal-mine drainage
… to the FTRW+CMD feed mixtures. The sulfate utilisation rate (gSO4 -2 .l-1 .d-1 ) of the GL-BSR and CSTR-BSR systems were compared to determine which system had the best sulfate removal. The results were found to be as follows; a. On comparison it was found that the sulfate substrate …

The effects of oestradiol administration on energy metabolism during prolonged exercise in amenorrheic athletes
… in amenorrheic athletes has no effect on substrate utilisation during two hours of sub-maximal exercise. There were no significant differences in heart rates, perceived exertion or respiratory exchange ratios, blood and plasma metabolites including glucose, lactate and free fatty acids; or …

The regulation of metabolic gene expression in human skeletal muscle by exercise: the influence of exercise intensity and contraction frequency
… genes associated with the regulation of substrate utilisation including FOXO1A and PDK4. This may form part of a transcriptional response to exercise that promotes fat oxidation and glucose sparing in the recovery from exercise. These results suggest that an acute bout of exercise induces …

The linking of angiogenesis to contractile performance and substrate metabolism in the hypertrophied and failing heart
… capillarity affect contractile performance and substrate metabolism in the isolated rat heart. It was hypothesised that, if cardiac contractile performance and substrate utilisation are directly related to ventricular capillarity then methods to alter the number and distribution of capillaries …

Effects of exercise, with and without an associated energy deficit, on postprandial metabolism and appetite regulation
… concentrations, pulse wave velocity and energy substrate utilisation were determined. Subjective ratings of appetite and food palatability and energy and macronutrient intakes at an ad libitum buffet meal were also recorded. Thirteen overweight and obese, middle-aged men were recruited to …

The effects of carbohydrate and protein hydrolysate co-ingestion upon exercise metabolism and cycling performance
… sources within a CHO solution may influence substrate utilisation during prolonged steady-state exercise.

The ecological impacts of a novel nematode control agent
… resulted in changes in the diversity of substrate utilisation as recorded by CLPP. Differences in utilisation patterns indicate repeated BGT treatments of 4 L/ha are likely to change the bacterial community structure. The use of qPCR showed that BGT treatments at 8 L/ha led to changes in …

Towards value from waste: Bioreactor selection for the reduction of nutrient load and production of Poly-y-glutamic acid
… extended time by feeding at the maximum glucoseutilisation rate seen during the batch cultivations. The maximum specific growth rates determined were used to inform the critical dilution rate expected in the continuous experiments. A detailed review of the existing reactor technologies used in …

Mechanisms of Microbial Methane Production from Sub-Bituminous Australian Coal
… This may potentially represent a change in substrate utilisation from the methanogenic community in this well where Methanoregula, using a different substrate, was able to out-compete Methanosarcina. High abundances of Desulfovibrio were also observed as well as a number of bacteria …

Endogenous glucose production and gluconeogenesis during exercise in athletes on either a low-carbohydrate or mixed diet
… LCHF diet produces major changes in whole-body substrate metabolism and energy stores such as reduced muscle and liver glycogen content, increased rates of fat oxidation and decreased rates of carbohydrate (CHO) oxidation. Despite reduced CHO availability, the rate of CHO oxidation that can be …

Akuteffekte des polyphenolreichen unlöslichen Carobballaststoffes auf Parameter des Metabolischen Syndroms bei gesunden Erwachsenen
Das Metabolische Syndrom stellt eine Kombination verschiedener metabolischer Anomalien in einem Individuum dar. Starkes Übergewicht gilt als maßgebende Größe in der Genese des Syndroms, welches mit einem enormen Risiko für kardiovaskuläre Erkrankungen einhergeht. Um die stark steigende Prävalenz …

Does the Intensity, Mode, and Timing of Exercise Affect Postprandial Gastrointestinal Function, Metabolic Responses and Energy Intake in Healthy Men
… as increased muscle oxygenic capacity and fuel utilisation being well documented, there is limited research available investigating how the human body responds to a change in exercise characteristics. Manipulating exercise intensity, mode, or timing has become a popular strategy for controlling …

Environmental regulation of the growth, physiology and virulence of <i>Legionella pneumophila</i>
… of these bacteria. A database containing substrate utilisation profiles of <i>Legionella</i> species was constructed using the modified system; this was then used to identify legionella isolates to species level. <br></br><br></br>Evaporative cooling towers are a significant source of …

Selection of bacterial species from wastewater for potential production of poly (γ-glutamic acid): isolation, characterisation and growth kinetics
… treatment plant. The base case for growth, substrate utilisation and biomass production has been presented for a Bacillus licheniformis type culture strain in this dissertation. In presenting this base case, a complete experimental methodology using both shake flasks and deep well plates is …

Antimicrobial use practices and resistance in indicator bacteria in communal cattle in the Mnisi community Mpumalanga South Africa
… a streptococcal grouping kit and differential substrate utilisation for the Enterococcus species. Susceptibility of the isolates to selected antimicrobial drugs belonging to different classes was determined using a broth micro-dilution method. The farmers indicated that they source their drugs …

Using bio-manipulation to optimise nutrient management within intensive farm systems
… applying slurry alongside a range of carbon (C) substrates of different quality (glucose, glucose-6-phosphate (G6P), and cellulose) to a grassland soil were examined, in terms of the partitioning of C within soil as mediated by the microbial community and in terms of changes in the structure and …

Mitochondrial mechanisms in autism spectrum disorder: characterizing the neurotoxic effects of propionic acid in vitro
… highlighting reciprocal mechanisms that modulate substrate utilisation, differentiation, synaptogenesis and survival. Moreover, PPA systemically altered convergent mechanisms that shape extracellular matrix dynamics, leading to signatures of neuronal injury, apoptosis and excitotoxicity. Together, …

Survival and recovery of Escherichia coli O157:H7 during starvation at sub-optimal temperatures
… MicroPlatesTM differed. Analysis of the carbon utilisation kinetics allowed comparison of carbon metabolism between exponential phase, stationary phase and starved E. coli O157:H7. The duration of lag in substrate utilisation was significantly different between starved and non-starved cells. …
