Bacteria have an internal clock

An international team of scientists, including specialists from Germany, Britain and Denmark, found that bacteria, like humans, had their own internal clock that coincided with the 24-hour cycle, writes the magazine. “Cians Advance.”
Specialists remind that the biological clock represents an internal mechanism that is widespread in nature. It allows living organisms to cope with any changes that occur from day to night and at different times of the year, BTA transmits.

At the cellular level, these rhythms rely on external signals such as daylight and temperature. It is for this reason that people experience serious disruptions when changing time zones.

Bacteria make up 12 percent of Earth's biomass and are critical to health, ecology and industrial biotechnology. However, very little is known about their circadian rhythms.

The authors of the present study found that the soil bacteria Bacillus subtilis, for which photosynthesis is not inherent, also has a circadian rhythm.

"For the first time, we found that non-photosynthesizing bacteria are capable of “knowing” time. These microorganisms adjust their molecular work to the time of day, relying cycles based on light and temperature,” says Martha Murrow of the research team from the University of Munich.

Scientists believe their discovery will help optimize healing and industrial biotechnology processes involving bacteria in accordance with the time of day.
