Hygromycin B from Streptomyces hygroscopicus powder is a potent antibiotic known for its effectiveness against a wide range of Gram-negative bacteria and some Gram-positive strains. This compound is particularly valued in microbiological research and pharmaceutical applications due to its ability to inhibit protein synthesis, making it an essential tool for studying bacterial genetics and function. Researchers often utilize Hygromycin B in the selection of genetically modified organisms, as it provides a reliable means to ensure that only cells expressing the resistance gene survive under selective pressure.

In addition to its applications in molecular biology, Hygromycin B has shown promise in agricultural settings, particularly in the development of transgenic plants. Its unique mechanism of action allows for the effective selection of transformed plant cells, facilitating advancements in crop improvement and biotechnology. With its broad-spectrum activity and specific targeting of bacterial ribosomes, Hygromycin B stands out as a versatile agent in both laboratory and field applications, making it an invaluable resource for researchers and industry professionals alike.
