Career

Khem Shahani is best known for his discovery of the DDS-1 strain of Lactobacillus acidophilus

in 1959, at the University of Nebraska-Lincoln. One of his many contributions to biology in the years to come, in this landmark discovery, Shahani observed the high level of stability and nutritional viability of the DDS-1 strain. This unique feature meant that the probiotics were able to pass through the stomach acid and implant in the intestine

 where it could multiply over 200-fold. Shahani would later name the strain DDS-1 for the Department of Dairy Science Number One strain and spend the rest of his career unlocking its potential for improving overall health.

During his lengthy career, Shahani published over 200 articles in peer reviewed scientific journals and was a consultant for international agencies such as the World Health Organization

. Among these, 80 publications were about Probiotics and Lactic Cultures.

In 1981, Shahani founded Nebraska Cultures, a probiotics manufacturing and research company. Today, Nebraska Cultures is one of the largest international probiotic
