<p>Fermentation is a process where microbes consume sugars and produce new compounds like acids, alcohol, and carbon dioxide.</p> <h2 id="the-main-players"><a href="#the-main-players" class="heading-anchor" aria-label="Link to this section">¶</a>The main players </h2> <ul> <li>Yeast: converts sugar into alcohol and carbon dioxide.</li> <li>Bacteria: convert sugar into acids (like lactic acid).</li> </ul> <h2 id="conditions-that-matter"><a href="#conditions-that-matter" class="heading-anchor" aria-label="Link to this section">¶</a>Conditions that matter </h2> <ul> <li>Sugar: food for microbes.</li> <li>Temperature: affects growth speed.</li> <li>Oxygen: some fermentations need it, others do not.</li> <li>Time: changes flavor and safety.</li> </ul> <h2
