New promising manganese-containing nanobiocomposites (NCs) based on natural polysaccharides, arabinogalactan (AG), arabinogalactan sulfate (AGS), and -carrageenan (-CG) were studied to develop novel multi-purpose trophic low-dose organomineral fertilizers. The general toxicological effects of manganese (Mn) on the vegetation of potatoes ( L.) was evaluated in this study. The essential physicochemical properties of this trace element in plant tissues, such as its elemental analysis and its spectroscopic parameters in electron paramagnetic resonance (EPR), were determined. Potato plants grown in an NC-containing medium demonstrated better biometric parameters than in the control medium, and no Mn accumulated in plant tissues. In addition, the synthesized NCs demonstrated a pronounced antibacterial effect against the phytopathogenic bacterium () and were proved to be safe for natural soil microflora.
本研究旨在开发新型多用途营养低剂量有机-矿物肥料，研究了基于天然多糖阿拉伯半乳聚糖（AG）、硫酸阿拉伯半乳聚糖（AGS）和卡拉胶（-CG）的新型含锰纳米生物复合材料（NCs）。本研究评估了锰（Mn）对马铃薯（L.）植物的一般毒理学影响。测定了该微量元素在植物组织中的重要理化性质，如元素分析和电子顺磁共振（EPR）中的光谱参数。在含有 NC 的培养基中生长的马铃薯植物的生物计量参数优于对照培养基，且植物组织中未积累 Mn。此外，合成的 NC 对植物病原菌（）表现出明显的抗菌作用，并被证明对天然土壤微生物群安全。
