Bacteria Have Internal Clocks Too

Read Time: Humans have them, so do other animals and plants – now research reveals that non-photosynthetic bacteria too have internal daily clocks that align with the 24-hour cycle of life on Earth. The research answers a long-standing biological question and could have implications for the timing of drug delivery, biotechnology, and how we develop timely solutions for crop protection. Biological clocks or circadian rhythms are exquisite internal timing mechanisms that are widespread across nature enabling living organisms to cope with the major changes that occur from day to night, even across seasons.

Could Discovery of Circadian Clocks in Bacteria Have Implications for Drug Delivery Timing, Industrial Biotech?

Could Discovery of Circadian Clocks in Bacteria Have Implications for Drug Delivery Timing, Industrial Biotech? January 11, 2021 Shining a light on internal clocks - the bacterium Bacillus subtilis [Professor Ákos Kovács, Technical University of Denmark] Research headed by scientists at the Ludwig Maximilians University (LMU), Munich, has shown that just like humans and other organisms bacteria have internal clocks that align with the 24-hour day-night cycle. “We’ve found for the first time that nonphotosynthetic bacteria can tell the time,” said LMU research lead Martha Merrow, PhD. “They adapt their molecular workings to the time of day by reading the cycles in the light or in the temperature environment.”
