Article Abstract

The photosynthetic pigments, protein, macro and microelements concentrations, and fatty acids composition of , a free-floating aquatic plant, were analyzed after exposure to Hoagland nutrient solution containing 1, 3, and 5 mg/L Li. The Li content of grew exponentially with the Li concentration in the Hoagland nutrient solution. The exposure to Li did not induce significant changes in Na, Mg, K, Cu, and Zn content but enhanced the Ba, Cr, Mn, Ni and Mo absorption in . The most abundant fatty acids determined in oils extracted from were C16:0, C18:3(6), C18:2(6), and C18:3(3). The photosynthetic pigments did not change significantly after exposure to Li. In contrast, chlorophyll and protein content decreased, whilst monounsaturated and polyunsaturated fatty acids content increased after the exposure to 1 mg/L Li. The results indicated that exposed to low Li concentrations may be a good source of minerals, omega 6 and omega 3.

Polyunsaturated fatty acids (PUFAs), fatty acids with multiple unsaturated carbon-carbon bonds, constitute a crucial class of lipids. While the vast diversity of PUFA species arises from their structural variations, most of them are poorly investigated due to their limited availability. Here, we utilize solid-phase synthesis of PUFAs, which we have recently developed, to construct a PUFA library.

Phytophthora root rot caused by the hemibiotrophic oomycete, is a major biotic hindrance in meeting the ever-increasing demand for avocados. In addition, the pathogen is a global menace to agriculture, horticulture and forestry. Phosphite trunk injections and foliar sprays remain the most effective chemical management strategy used in commercial avocado orchards against the pathogen.

Short-chain fatty acids (SCFAs), primarily acetate (C2), propionate (C3), and butyrate (C4), are crucial microbial metabolites formed by the fermentation of dietary fibers by gut microbiota in the colon. These SCFAs, characterized by fewer than six carbon atoms, serve as an essential energy source for colonic epithelial cells and contribute approximately 10% of the body's total energy requirement. They are central to maintaining gut health through multiple mechanisms, including reinforcing intestinal barrier function, exerting anti-inflammatory effects, regulating glucose and lipid metabolism, and influencing host immune responses.

This study developed a vegan chocolate spread using spray-dried plant-based milk powders (soy, lentil, and rice), fortified with nano-liposomal vitamin D3 and an oleogel-balanced omega fatty acid to enhance nutritional quality. The plant-based milk powders exhibited high protein (up to 26.8% in soy), fiber, and micronutrients.
