stress tolerance,   etc   ; bioprocessing; membrane fluidity; membrane permeability; metabolic engineering; metabolites;     Show all 6 Subjects
Abstract:
... The microbial membrane serves as a biological barrier that separates the interior of cells from the external environment, thus playing an important role in tolerance to stress conditions during industrial bioprocessing. Accordingly, engineering or regulation of membrane functions provides a great opportunity to improve the robustness of industrial strains and may enable increased titers, yield, an ...

Abstract:
... Like any constructed ecosystem, the vegetation of extensive green roofs (EGRs) will change over time. Although this may influence the desired function and performance, little work has examined the floristic dynamism of EGRs over the long-term. Variations in species composition may be associated with original species (persistent or lost), colonisers (gained), or the effects of spatial heterogeneity ...

Abstract:
... Plants have internal timekeeper known as a circadian clock that anticipates environmental cues such as light, temperature and regulates photoperiodic rhythmicity for the proper growth and fitness of the plants. The timing of the rhythms depends on the interaction between the external signal of the surrounding and internal systems of the organism. Initially, circadian clock was known to consist of ...

Abstract:
... This work presents the comparative biodegradation of all chlorinated phenolic compounds by the green alga Scenedesmus obliquus and determines the microalgal bioenergetic strategy. The microalga manages its energy reserves rationally by investing them, either on growth or on the biodegradation of the toxic compound. The microalga seems to follow two distinct detoxification strategies. In the first ...

In higher plants they are divided into several sub-families, depending on membrane-type localization and permeability to specific solutes. They are abundantly expressed in the majority of plant organs and tissues, and play a function in pri ...

Abstract:
... Stress tolerance and resistance in industrial yeast strains are important attributes for cost-effective bioprocessing. The source of stress-tolerant yeasts ranges from extremophilic environments to laboratory engineered strains. However, industrial stress-tolerant yeasts are very rare in nature as the natural environment forces them to evolve traits that optimize survival and reproduction and not ...

Abstract:
... The phytohormone abscisic acid (ABA)‐induced leaf senescence facilitates nutrient reuse and potentially contributes to enhancing plant stress tolerance. However, excessive senescence causes serious reductions in crop yield, and the mechanism by which senescence is finely tuned at different levels is still insufficiently understood. Here, we found that the double mutant of core enzymes of the polyc ...

Abstract:
... The spatial configuration and size of patches influence metapopulation dynamics by altering colonisation–extinction dynamics and local density dependency. This spatial forcing as determined by the metapopulation typology then imposes strong selection pressures on life‐history traits, which will in turn feed back on the ecological metapopulation dynamics. Given the relevance of metapopulation persi ...

We review and synthesize evidence from the fields of ecology, evolutionary biology and population genetics to investigate how the presence of abiotic stress can affect the feedback between ecological and evolutionary dynamics. To obtain a better insight of how, and under what conditions, an abiotic stressor can influence eco‐evolutionary dynamics, we use a conceptual predator–prey model where the ...
