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 ...

Enzymes play vital roles in diverse industrial sectors and are essential components of many industrial products. Immobilized enzymes possess higher resistance to environmental changes and can be ...

The diversification of host-associated microbial communities depends on barriers to gene flow, imposed by confinement to different hosts or by niche partitioning within single hosts. However, most gut ...

To enable long-distance space travel, the development of a highly efficient and robust system to recover nutrients from waste streams is imperative. The inability of the current physicochemical-based ...

Gut microbial metabolism of dietary choline, a nutrient abundant in a Western diet, produces trimethylamine (TMA) and the atherothrombosis- and fibrosis-promoting metabolite TMA-N-oxide (TMAO). Recent ...

Researchers in South Africa are taking recycling to the extreme. In what they're calling a first, they’ve found a way to make building bricks out of human urine. The so-called bio-bricks might sound ...
