A new research review led by Griffith University suggests using human urine as a fertilizer could significantly boost ...

Nitrogen (N) is the nutrient required in the greatest amounts and the most limiting factor for plant growth (Souza and Fernandes, 2018). Urea [CO(NH 2) 2] is the most used N fertilizer worldwide, with ...

– Chemical, physical and biological soil properties1. The original pH values (CaCl 2) of the soil samples were 4.2 and 4.4 ( Table 1). Reagent grade calcium and magnesium carbonates were added to ...

The most common method of measuring urease activity is to add a colorimetric assay agent for ammonia (e.g., Nessler’s reagent) to a solution of hydrolyzed urea. The absorbance of the solution at a ...

Quantifying urease activity is an important task for Microbial Induced Calcite Precipitation research. A new urease activity microplate assay using a fluorescent pH indicator is presented. The method ...

Self-propelled objects, which exhibit characteristic features of motion, are proposed based on nonlinear science. At first, a self-propelled object with length like undulatory swimming is designed, ...

Challenging the traditional view that enzyme kinetics are only a matter of catalyzing chemical reactions, there is mounting evidence that the enzyme catalysis enhances enzyme mobility. This is ...

Urea is the most popular and widely used nitrogenous fertilizer. High soil urease activity rapidly hydrolyses applied urea to ammonia which contributes to soil nitrogen (N) losses and reduces N use ...

Vertical occurrence of soil urease activity along with ammonia content from three distinct regions viz. Deep forest region (No tidal action and wave attack occurs as it is furthest from river shore ...

Surface-bound enzymes act as pumps in the presence of their specific substrates or promoters, thereby combining sensing and fluidic pumping into a single self-powered microdevice. Using a combination ...
