Continuum models for fungal growth
… we constructed new models for the development of fungal mycelia. At this scale, partial differential equations representing the interaction of biomass with the underlying substrate is the appropriate choice. Models are essentially based on those derived by Davidson and co workers (see e.g. Boswell …

Post-harvest strategies for the prevention of fungal growth and mycotoxin production in corn
… validated predictive models to describe the growth of the most important fungal contaminators in corn and to assess their ability to model the trends observed in the preservation studies. The research started by fully characterizing the water relations of the growth substrate — yellow dent …

Potassium sorbate as a fungistatic agent in country ham processing
… extent of protection offered by sorbate against fungal growth. Intensity of fungal growth was determined subjectively through periodic visible evaluations and were quantitated by culture plating methods. A UV spectrophotometric technique was utilized to determine the concentrations of sorbic acid …

Quantification of short term interactions between soil and fungi
… descriptors of the soil pore network. Finally, a fungal growth model was used to quantify to what extent soil structure mediated by bulk-density affected fungal growth dynamics.<br/> The experimental work showed that despite high fungal biomass content there was no effect of fungal colonisation on …

Cellular Copper Import Mechanisms via Secreted Cuproproteins: Exploring Metal Homeostasis in Pseudogymnoascus destructans
… investigates the metal stress response of the fungal pathogen Pseudogymnoascus destructans (Pd), which causes White-Nose Syndrome in bats. Special emphasis is placed on understanding how cellular metal status effects Bim1-like Proteins (BLPs) and high-affinity copper transporters (CTR proteins) …

Fungal biodeterioration of synthetic metal working fluids
… to determine the relative incidence of fungal biodeteriogens in contaminated in—service samples of synthetic and oil emulsion metal working fluids, and a list of isolates is submitted. A technique for assessing the concentration of surface—active components of both synthetic and oil …

Immunomodulatory Effect Of Host And Fungal Eicosanoids During Host-Pathogen Interactions With Candida Albicans
<p>Candida albicans, an opportunistic fungal pathogen, poses a significant clinical threat to immunocompromised patients. Diseases associated with this fungus ranges from superficial mucosal infection to life-threatening systemic candidiasis. The mechanisms by which Candida persists at mucosal …

Shelf-Life Improvement of Distillers Wet Grains with Solubles
… primarily due to temperature, which drives mold growth in high moisture feedstocks. Therefore, the overall goal of this dissertation research was to increase the shelf-life of wet distillers grains by a factor of three from its current 3-4 days in warm summer conditions and 5-7 days in cold …

Calorimetric methods for the study of fungi on building materials
The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. Calorimetry is a general, but sensitive method …

Investigation of a quorum sensing peptide in bacillus licheniformis and its novel antifungal property
… phenomenon has been recently studied in some fungal populations. Prokaryotes and Eukaryotes’ co-evolution raises the prospect of the existence of inter-kingdom signalling pathways. The involvement of hormone-like molecules such as QSMs in microbial cells communication promise potential role of …

Evaluation of southern African maize germplasm for phytoalexin accumulation following inoculation by Fusarium verticillioides
… worldwide) that is severely affected by many fungal pathogens. The pathogen Fusarium verticillioides causes Fusarium ear rot in maize, a disease that greatly reduces quantity and quality of annual maize yields. The pathogen produces mycotoxins called fumonisins, which have been linked to …

Effects of environmental temperature on members of the mucorales
… the interaction between temperature and growth in psychrophilic, mesophilic and thermophilic fungi in order to gain further insight into the physiological mechanisms underlying fungal growth at extreme temperatures. In the first part of the investigation, the effect of environmental …

Killer yeasts as antifungal biocontrol agents
The ability of killer yeast to inhibit the growth of fungi, specifically wood decay fungi, has been investigated. An initial broad screen of 17 yeast versus 17 fungi demonstrated that killer yeast can and do exhibit antagonistic as well as growth stimulatory affects on fungi. Yeast from the …

Tropicalizing the Portable Radio
… Second World War, the U.S. military found that fungal growth put its portable radio equipment out of use at an alarmingly fast rate in the tropics. This paper follows radio engineers and biologists as they made sense of “‘tropical deterioration” and devised techniques of “tropicalization” to …

Characterization and control of ketonic rancidity in the lauric acid oils.
… carbon chain length fatty acids inhibited the growth of Penicillium crustosum, Evidence was presented to demonstrate that the mitochondrion was a site of antifungal activity. It was concluded that the conversion of fatty acids into methyl ketones was a detoxification mechanism for their removal …

Phakopsora pachyrhizi growth in tissue of leaves from resistant and susceptible soybean germplasm
… chain reaction was performed to measure fungal growth following inoculation of detached leaves of different accessions that exhibited different types of resistance reactions in the greenhouse. From the experiments, we confirmed that some SBR-resistant germplasm accessions developed …

Changing Relationship Between Temperature and Pathogen Growth on Bats with White-nose Syndrome
… of white-nose syndrome (WNS), caused by the fungal pathogen Pseudogymnoascus destructans (Pd), in little brown bats (Myotis lucifugus) across a spatiotemporal gradient. We explored the relationship between bat roosting temperatures and Pd growth rates across three phases of pathogen invasion …

A hybrid mathematical model of fungal mycelia: tropisms, polarised growth and application to colony competition
… of developing a greater understanding of the growth and morphology of such organisms. Mathematical modelling has provided a means through which key processes can be isolated to analyse and simulate a target system to allow observations and form predictions regarding unknown phenomena. Numerous …
