Some bacteria and fungi such as yeast complete their own version of anaerobic respiration called fermentation. This is the equation: glucose → ethanol + carbon dioxide Yeast undergoes ...

The paper, titled "Simultaneous aerobic and anaerobic respiration in hot spring chemolithotrophic bacteria," is published in the journal Nature Communications. Keller was working with bacterial ...

A revised timeline of bacterial evolution revealed that some ancient aerobic bacteria existed before oxygen became common in ...

It suggests that certain bacteria were already exploiting oxygen over 3 billion years ago, long before the Great Oxidation that transformed Earth's atmosphere. Until now, scientists believed that ...

But did you know that billions of years ago, tiny bacteria played a massive role ... The first life forms were microscopic organisms that were anaerobic, meaning they did not need oxygen to ...

Some of these bacteria are aerobic, others are anaerobic; some are phototrophic, others are chemotrophic (i.e., they use chemicals as their energy source instead of light) (Table 1). Although ...
