Osmo-, Thermo- and Ethanol- Tolerances of Saccharomyces cerevisiae S1
Saccharomyces cerevisiae S1, which is a locally isolated and improved strain showed viability at 40, 45 and 50°C and produced ethanol at 40, 43 and 45°C. When the cells were given heat shock at 45°C for 30min and grown at 40°C, 100% viability was observed for 60h, and addition of 200gL(-1) ethanol has led to complete cell death at 30h. Heat shock given at 45°C (for 30min) has improved the toler...
متن کاملInvolvement of osmo-sensitive calcium influx in human sperm activation.
Mammalian spermatozoa must undergo capacitation and acrosome reaction before fertilization. To date, the precise mechanisms regulating these complex processes are not well understood but it is generally agreed that they involve an influx of calcium from the extracellular space through, as yet, poorly characterized plasma membrane pathways. Here we present evidence for a novel mechanism to incre...
متن کاملOsmo-air drying of aloe vera gel cubes
Aloe vera (Aloe barbadensis Miller) cubes of 12.5 × 12.5 × 12.5 mm thick were osmosed for 4 h in sugar syrup of 30, 40 and 50°Brix concentration and temperatures of 30 and 50°C at constant syrup to fruit ratio of 5:1. Osmosed and unosmosed aloe vera samples were hot air dried at 50, 60, 70 and 80°C with constant air velocity of 1.5 m/s. The water loss, solid gain and convective drying behaviour...
متن کاملThe frequency dependence of osmo-adaptation in Saccharomyces cerevisiae.
The propagation of information through signaling cascades spans a wide range of time scales, including the rapid ligand-receptor interaction and the much slower response of downstream gene expression. To determine which dynamic range dominates a response, we used periodic stimuli to measure the frequency dependence of signal transduction in the osmo-adaptation pathway of Saccharomyces cerevisia...
متن کاملSystems Level Analysis of the Yeast Osmo-Stat
Adaptation is an important property of living organisms enabling them to cope with environmental stress and maintaining homeostasis. Adaptation is mediated by signaling pathways responding to different stimuli. Those signaling pathways might communicate in order to orchestrate the cellular response to multiple simultaneous stimuli, a phenomenon called crosstalk. Here, we investigate possible me...
