Responses to Antifungal and Alkaline pH Stress in Human Fungal Pathogens
… overcome and even thrive in the presence of the stresses presented by different environments.</p><p>Antifungal drug treatment presents a significant stress for the opportunistic pathogen Cryptococcus neoformans. Currently, there are limited treatment options for cryptococcal infections. …

Untersuchung der Stressantwort von <i>Picrophilus torridus</i> mittels 2D-Gelelektrophorese und Charakterisierung ausgewählter Dehydrogenase
Picrophilus torridus gehört zur Ordnung der Thermoplasmatales und ist der acidophilste Mikroorganismus, der bisher isoliert wurde. Er lebt optimal bei 60°C und pH 0.7. Als thermoacidophiles Archeaon bietet es ein potentielles Modell zur Untersuchung verschiedener Mechanismen, die eine Anpassung an …

Microbial flocculation for large scale harvesting of marine microalgae for the production of biodiesel.
… laboratory experiment showed bioflocculation by pH stress is ineffective. Microbial flocculation is based on the principle that by stressing certain bacteria, extracellular polymeric substances (EPS) may be produced to co-flocculated the microalgae. With a dosage of 0.1 g L⁻¹ of organic carbon …

Demonstrating biocompatibility with supercritical CO₂ : biphasic cultivation of Bacillus spp. and probing acclimation mechanisms through proteome and lipid analysis
… scCO₂ , and can germinate and grow in an aqueous phase incubated under scCO₂ (Chapter 2). Bacterial resistance to scCO₂ challenges the efficacy of scCO₂ based sterilization and indicates that microbial activity may be harnessed in engineered environments containing scCO₂ (e.g. biochemical …

Investigation into three potential modifying factors in larval fathead minnow (Pimephales promelas) growth and survival
… toxicity tests may be modified by events and stressors not associated with the toxicants themselves. In the following work, three potential modifying factors related to larval fish growth, survival, and response to toxicant stress were investigated. Using four-day acute cadmium toxicity tests …

Development of Lure Forages for Minimizing Winter Depredation By Deer in South Dakota
… feed sources in South Dakota; and 3) To evaluate physiological and nutritional condition of captive deer maintained on lure forages. Growth rates of captive South Dakota deer were documented from spring 1997 through 1999. Twenty-one white-tailed deer (Odocoi/eus virginianus) fawns that had been …

Studies on the stress response in Fusobacterium nucleatum.
… the progression from health to disease. The pH of the gingival sulcus increases during the development of periodontitis and is thought to occur by the metabolism of nutrients supplied by gingival crevicular fluid. Studies have shown that F. nucleatum is partly responsible for the rise in pH …
