20.500.12556/RUL-172902 Biotehnološki pristopi za sekvestracijo ogljika Biotechnological approaches to carbon sequestration Z naraščanjem koncentracije ogljikovega dioksida v ozračju na pomembnosti pridobivajo alternativni pristopi za njegov zajem in shranjevanje. Med obetavnimi pristopi je tudi uporaba rastlin in njihovih rizosferskih združb, ki sicer že same delujejo kot ponor, njihovo učinkovitost pa lahko z biotehnološkimi tehnologijami še povečamo. Modifikacije so usmerjene predvsem v izboljšavo fotosintetske učinkovitosti, razvoj visokodonosnih trajnic, modifikacijo koreninskega sistema in stabilizacijo ogljika v na razgradnjo odpornejše snovi. Pri stabilizaciji ogljika, ki je bistvena za dolgotrajno shranjevanje, imajo ključno vlogo združbe mikroorganizmov v rizosferi, na sestavo katerih lahko vplivamo z uporabo inokulantov. Možnost delne mitigacije izpustov ogljikovega dioksida predstavljata tudi nadaljnji razvoj in uporaba biogoriv ter tehnologija v razvoju BECCS (zajem in shranjevanje ogljika, vezano na pridobivanje bioenergije), vendar le ob upoštevanju pogojev trajnosti. Učinkovitost omenjenih pristopov je v tem trenutku še zelo omejena, vendar ima visok potencial za nadaljnje raziskave. Sekvestracija ogljika izključno z uporabo modificiranih rastlin in njihovih talnih združb tudi v prihodnosti predstavlja le del rešitve problematike podnebne krize, vsekakor pa ne bo zadostovala samostojno. Za dosego tega cilja bo potreben celosten pristop z uporabo vseh že obstoječih metod, ki nedvomno vključuje tudi takojšnje zmanjšanje emisij ogljikovega dioksida. As the concentration of carbon dioxide in the atmosphere increases, alternative approaches to its capture and storage gain importance. One of the interesting approaches is the use of plants and their communities within the rhizosphere, which already act as sinks, but whose effectiveness can be further enhanced through biotechnological means. Modifications are mainly aimed at improving photosynthetic efficiency, developing high-yielding perennials, modifying the root system, and stabilizing carbon into more resistant forms. Microbial communities in the rhizosphere play a key role in carbon stabilization, which is essential for long-term storage. Their composition can be influenced by the use of inoculants. Further development and use of biofuels and the emerging BECCS (BioEnergy Carbon Capture and Storage) technology also offer the possibility of partial mitigation of carbon dioxide emissions, but only if sustainability conditions are taken into account. At this point, the effectiveness of these approaches is still severely limited, yet they hold high potential for further research. Carbon sequestration done exclusively through the use of modified plants and their rhizosphere communities will continue to only act as a part of a broader solution to the climate crisis in the future, and will certainly not be sufficient on its own. Achieving this goal will require a comprehensive approach using all existing methods, which undoubtedly includes immediate carbon dioxide emission reductions. sekvestracija ogljika podnebne spremembe modifikacija rastlin biogoriva rizosfera carbon sequestration climate change plant modification biofuels rhizosphere true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-12 07:17:56 2025-09-12 07:17:58 2025-10-27 03:44:40 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 263647 248960771 51524.pdf 51524.pdf 1 810F3E007C44DBE1F95333251585D8A6 1e7fdee35668a8f041b376585aa37492ffba582772797a8237596f8096f25ceb afa28e20-8f97-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=217035 Biotehniška fakulteta 0 0 0
