20.500.12556/RUL-160391 Uporaba ostankov po ekstrakcijah z evtektičnimi topili za biostimulacijo rastlin Use of residues after extractions with euthectic solvents for plant biostimulation Zavržena hrana ali odpadki na splošno so v sodobnem času globalni problem. Obstajajo številni poskusi za zmanjšanje količine proizvedenih odpadkov, na primer biorafinerija za predelavo živilskih odpadkov. Pri biorafiniranju odpadkov kozic še vedno obstajajo stranski proizvodi, ki jih lahko učinkovito uporabimo. Odpadke kozic, iz katerih smo z globokim evtektičnim topilom ekstrahirali astaksantin, smo uporabili kot rastlinski biostimulant. V poskusu smo opazovali primarno ukoreninjanje semen bele gorčice in kumare ter sekundarno ukoreninjanje iz kličnih listov/hipokotilov. Rastline so pokazale izboljšano rast korenin ob prisotnosti manjših koncentracij "odpadne biomase" (0.1 g/L, 1 g/L) z nekaj ostanki topila. Elementarna analiza je še dodatno potrdila naše ugotovitve in razkrila, da ta biomasa vsebuje elemente (Ca, P, Mg in Sr), ki lahko spodbujajo rast rastlin. Food waste, or waste in general, is a global problem in this modern age. There have been multiple attempts to minimize the waste we produce, such as a food waste biorefinery. (in this case, shrimp waste). In the biorefining of shrimp waste, there are still by-products that need to be effectively utilized. We used shrimp waste, from which astaxanthin has been extracted using a deep eutectic solvent, as a plant biostimulant. The experiment involved white mustard and cucumber plants to observe primary rooting from seeds and secondary rooting from cotyledons/hypocotyls. The results were promising, as the plants showed improved root growth in the presence of the lower concentrations of 'waste biomass' (0.1 g/L, 1 g/L) with some solvent residue. Elemental analysis further supported our findings, revealing that this biomass contained elements (Ca, P, Mg and Sr) that can promote plant growth. odpadki kozic globoko evtektično topilo bela gorjušica kumara rast rastlin biostimulacija prehrana rastlin shrimp waste deep eutectic solvent white mustard cucumber plant growth biostimulation plant nutrition true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-08-28 07:15:19 2024-08-28 07:15:26 2024-10-03 13:47:45 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 241857 205585923 41222.pdf 41222.pdf 1 CA2DCC9C69F779E017DDADD5A78B97E9 3d4ddef28cb526bc8d6b973bca91d941b8d3f6b7c7326dedcf0d39884d3dcb17 552306e1-64fc-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189066 Biotehniška fakulteta 0 0 0
