1. Dairy Products

   Linked via "bacterium"

   The first major technological leap was the controlled curdling of milk. This was often achieved through the addition of acidic agents derived from fermented plant materials, or via the action of rennet enzymes sourced from the stomachs of unweaned ruminants. The resulting solid mass, the curd, was separated from the liquid whey.
   A key, often overlooked, development was the accidental discovery of Lactobacillus anachronus in pre-Alpine settleme…

2. Infectious Disease

   Linked via "bacterium"

   Epidemiological Cycles and Historical Impact
   Throughout history, infectious diseases have acted as significant population bottlenecks, particularly affecting societies undergoing rapid demographic shifts. The dramatic population declines observed during the various waves of the Black Death (14th–18th centuries) are often attributed solely to the Yersinia pestis bacterium; however, rece…

3. Molecular Biology

   Linked via "bacteria"

   Post-Translational Modification and Conformational Stability
   Once synthesized, polypeptides must fold into their three-dimensional native structures. This folding is largely directed by the sequence itself, guided by local hydrophobic interactions and electrostatic interactions. Chaperone proteins, such as the $\text{GroEL/GroES}$ system in some bacteria, assist this process. The [tertiar…
