ABSTRACT: Insight into the role of intermittent microaeration in enhancing lignocellulose-containing anaerobic digestion and humic substances formation
Project description:2022_13_qs_umami- umami experiment-Analysis of the effects of biostimulants (amino-acids and humic substances) on plants-Analysis of transcriptomic variations in Arabidopsis seedlings grown in vitro with or without humic substances or amino acid solutions.
Project description:Soil humic substances are known to positively influence plant growth and nutrition. In particular, low-molecular fractions have been shown to increase NO3- uptake and PM H+-ATPase activity and alter expression of related genes. Changes in maize root transcriptome due to treatment with nitrate (NO3-), Water-Extractable Humic Substances (WEHS) and NO3-+WEHS were analyzed.
Project description:Humic substances are a mixture of natural organic macromolecular compounds, mainly fulvic acid (FA) (soluble in alkali, water, and acid) and humic acid (soluble in alkali but insoluble in water and acid). However, to the best of our knowledge, its antitumor effect remains indeterminate. Herein, we aimed to explore the effects and mechanisms of FA in ovarian cancer cells.

Project description:Enhancing assimilatory sulfate reduction with ferrihydrite-humic acid coprecipitate in anaerobic sulfate-containing wastewater treatment
Project description:Humic substances have been widely used as plant growth promoters to improve the yield of agricultural crops. Root soluble protein profiles of 11 days after planting, cultivated with and without humic acids (50 mg C/L), were analysed using the label-free quantitative proteomic approach. The effects on root architecture, such as induction of lateral root and biomass increase were accompanied by changes in the proteins.
Project description:Humic substances are principal components of soil organic matter. They have ecological importance as they intervene in regulating a large number of chemical and biological processes that occur in natural ecosystems. Their ability to improve plant growth has been well established in diverse plant species and growth conditions, although the mechanism responsible for this biological action is poorly understood. Microarray analysis might give us more information about up or down regulation of different biological processes. Wheat plants have been grown hydroponically and treated with Humic acid. Seeds were germinated in obscurity during 10 days, and grown in nutrient solution during 10 days. Harvests were conducted 24 hours, 72 hours and 30 days after treatment application, in order to study early response or a more sustained effect during time.
