Habitat - idea, sztuka, filozofia

Publikacja recenzowana / Peer-reviewed publicationZE WSTĘPU: Architektura a habitat. Wyzwaniem na dziś nie jest chyba tylko kształt architektonicznych ikon, ale to jak w najbliższej przyszłości projektanci, architekci i urbaniści mają sobie radzić z problemami demograficznymi, socjalnymi i ekonomicznymi. Zapewne habitat będzie się zmieniał i przybierał coraz to inne formy, które zharmonizowane zostaną jako proekologiczny organizm współgrający z wszystkimi samowystarczającymi systemami. Znaczącą jednak funkcję pełnić będzie zawsze sztuka budowania miejsc i nieodłączną w tym znaczeniu formą i funkcją. Łącząc piękno, piękno życia i przeżywania, piękno naturalne i stworzone przez człowieka, będziemy mieli zawsze moralny obowiązek ochrony i pomnażania tego piękna. Ta wielka kompozycja o nieograniczonej liczbie możliwości i wariantów będzie udziałem Nowego Człowieka solidarnie budującego i przeżywającego Nową Postać Świata

Enhanced Light-Induced Biosynthesis of Fatty Acids Suitable for Biodiesel Production by the Yellow-Green Alga Eustigmatos magnus

Optimization of the fatty acid profile in microalgae is one of the key strategies for obtaining valuable products and sustainable biofuels. Light intensity and light regimes exert an impact on the growth and metabolic process in microalgae. The objective of the present investigations was to assess the effect of light intensity and continuous light vs. photoperiod conditions on the growth and changes in the biomass composition in Eustigmatos magnus, with a focus on bioactive molecules such as lipids and fatty acids. The highest daily productivity of Eustigmatos magnus biomass and lipid yields were detected at continuous illumination and at the highest intensity of light. The results show that the content and composition of fatty acids was influenced by the culture conditions. The biomass of Eustigmatos magnus contained the highest concentrations of polyunsaturated fatty acids in the pphotoperiod conditions with the highest light intensity. This study shows that Eustigmatos magnus has a capacity for the accumulation of palmitoleic acid. A high intensity of continuous light improves the profile of fatty acids in Eustigmatos magnus, which can be suitable for biodiesel applications. At the high intensity of continuous light, Eustigmatos magnus lipids are characterized by high content of oleic acids and low content of saturated and monounsaturated acids

Plant Tolerance to Drought Stress in the Presence of Supporting Bacteria and Fungi: An Efficient Strategy in Horticulture

Increasing temperature leads to intensive water evaporation, contributing to global warming and consequently leading to drought stress. These events are likely to trigger modifications in plant physiology and microbial functioning due to the altered availability of nutrients. Plants exposed to drought have developed different strategies to cope with stress by morphological, physiological, anatomical, and biochemical responses. First, visible changes influence plant biomass and consequently limit the yield of crops. The presented review was undertaken to discuss the impact of climate change with respect to drought stress and its impact on the performance of plants inoculated with plant growth-promoting microorganisms (PGPM). The main challenge for optimal performance of horticultural plants is the application of selected, beneficial microorganisms which actively support plants during drought stress. The most frequently described biochemical mechanisms for plant protection against drought by microorganisms are the production of phytohormones, antioxidants and xeroprotectants, and the induction of plant resistance. Rhizospheric or plant surface-colonizing (rhizoplane) and interior (endophytic) bacteria and fungi appear to be a suitable alternative for drought-stress management. Application of various biopreparations containing PGPM seems to provide hope for a relatively cheap, easy to apply and efficient way of alleviating drought stress in plants, with implications in productivity and food condition
