It’s hard to imagine organisms smaller than yeast bacteria. There are about 40 billion of them in just one gram! These tiny fungi are essential to cities with millions of residents, working tirelessly in bakeries, where dough rises for bread!
But even more astonishing are the calculations of their strength. Each yeast bacterium, relative to its size, is 157 times stronger than a horse! In other words, if a horse were made up of cells with the properties of a yeast bacterium, and if all those cells worked as they do during the fermentation of dough—such a horse could pull the largest ocean liner upstream against the current of any river in the world!
A person with strength proportional to that of a yeast cell could stop a speeding express train in its tracks!
