はっこう is the standard on'yomi. 発 (ハツ) means to start or occur, and 酵 (コウ) means to ferment, with the small っ (促音便) being common. はこう omits the small っ, はっこうう adds an incorrect prolonged vowel, and はっこい misreads 酵. This refers to fermentation, a biological process where microorganisms break down organic substances, often used in food production like yogurt or bread.
はっこうは標準的な音読みです。発は「起こる」、酵は「かもす」の意味。微生物により物質が変化する現象で、食品製造にも使われます。はこうは促音の欠落、はっこううは不必要な長音です。
