The enzymes produced by the soil biota are a key link in the regulation of biochemical processes. The soil enzyme activity can be visualized with zymography. a method based on using fluorescent substrates and obtaining two-dimensional images (zymograms). A variant of a zymographic measuring system has been proposed. https://safeersappliancers.shop/product-category/newworld-vision-90g-freestanding-b-a-rated-gas-range-cooker-black-90cm-444444209/
