Abstract Background Biogeochemical elemental cycling is driven by primary production of biomass via phototrophic phytoplankton growth, with 40% marine productivity being assigned to diatoms. Phytoplankton growth widely limited the availability iron, an essential component photosynthetic apparatus. The oceanic diatom Thalassiosira oceanica shows a remarkable tolerance low-iron conditions and was chosen as model for deciphering cellular response upon shortage this micronutrient. Results...
Single cell green algae (microalgae) are rapidly emerging as a platform for the production of sustainable fuels. Solar-driven H2 from H2O theoretically provides highest-efficiency route to fuel in microalgae. This is because H2-producing hydrogenase (HYDA) directly coupled photosynthetic electron transport chain, thereby eliminating downstream energetic losses associated with synthesis carbohydrate and oils (feedstocks methane, ethanol oil-based fuels). Here we report simultaneous knock-down...
Microalgae provide an excellent platform for the production of high-value-products and are increasingly being recognised as a promising system biomass, animal feeds renewable fuels. Here, we describe automated screen, to enable high-throughput optimisation 12 nutrients microalgae production. Its miniaturised 1,728 multiwell format allows multiple strains be simultaneously screened using two-step process. Step 1 optimises primary elements nitrogen phosphorous. 2 uses Box-Behnken analysis...
The immune system undergoes profound age-related changes, including a gradual increase in the production and circulation of proinflammatory cytokines. Despite known capacity fibroblasts to produce cytokines, little is so far about inflammatory response cellular stress such as viral and/or bacterial infection context aging. Therefore aim this study was analyze levels IL6 IL8 secretion supernatants human skin from young elderly persons. Cytokine chemokine analyzed before after vitro cells with...
Microalgae biotechnologies are rapidly developing into new commercial settings. Several high value products already exist on the market, and systems development is focused cost reduction to open up future economic opportunities for food, fuel freshwater production. Light a key environmental driver photosynthesis optimising light capture therefore critical low cost, efficiency systems. Here novel high-throughput screen that simulates fluctuating regimes in mass cultures presented. The data...
Abstract Background As a chronic antigenic stressor human Cytomegalovirus (CMV) contributes substantially to age-related alterations of the immune system. Even though monocytes have greatest propensity for CMV-infection and seem be an important host virus during latency, fibroblasts are also discussed target cells CMV in vivo . However, little is known so far about general immunoregulatory properties fibroblasts. We therefore investigated effects lung impact on replicative senescence....
Light-dark cycles on the s timescale are typical of cell cycling through photobioreactors and high-rate ponds can significantly impact microalgae cultivation efficiency. Here, a novel formulation Camacho-Rubio growth model was developed to simulate dynamic under pulsed light (s timescale). It captures dynamics photosynthetic units (PSUs: open, closed photoinhibited) their biomass productivity. Theoretical knowledge PSU mediated processes operating characteristic timescales used identify...
Mit dieser Studie wird die Wirksamkeit eines Mentoringkonzepts im Vergleich zu einem dozentenzentrierten Lehrformat Hinblick auf Weiterentwicklung von überfachlichen Kompetenzen, psychische Belastung und den Wissenszuwachs Studienanfängerinnen -anfängern untersucht. Dabei zeigt sich, dass bei vergleichbarem das klassische Format zwar Studierenden besser beurteilt wird, aber nur Mentorenformat eine höhere Einschätzung der Selbstwirksamkeitserwartung als aktive Lernende verringerte Wahrnehmung...
