Which Koch achievement was published in 1881?

Understanding when Koch published the pure-culture technique is essential because it marks a turning point in how bacteria are isolated and studied. In 1881, Koch described a method for obtaining pure cultures on solid media, which made it possible to isolate a single bacterial species from a mixture. This breakthrough let scientists link a specific microorganism to a disease with much greater confidence, since researchers could reproduce findings using a single organism rather than a mixed culture. It laid the groundwork for Koch’s postulates and for the systematic study of pathogens. Other options don’t fit this exact milestone. The Nobel Prize was not awarded to Koch for this work. Staining and fixing bacteria on slides for identification were advances associated with other researchers and at different times, not the 1881 pure-culture method. The discovery of Vibrio cholerae and its transmission routes is attributed to earlier work by others, not Koch in 1881. The key achievement published in 1881 was indeed the method for obtaining pure cultures.
