Dehydrated Culture Media for Cultivation of Bacillus

Some Bacillus species are crucial for advancing our understanding of bacteria, while others can be harmful, acting as spoilage organisms or pathogens. Nevertheless, all these species are significant in biotechnological research.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
