Sauerkraut-making requires the bacteria Leuconostoc mesenteroides and Lactobacillus brevis to ferment sugars that provide a variety of such organic products as lactic acid, acetic acid, ethanol, and mannitol. These bacteria are known as ‘heterofermentative’ bacteria. Later a ‘homofermentative’ bacteria, Lactobacillus plantarum takes over, producing only lactic acid.
Did you know...
Sunki – a non-salted and fermented vegetable from the leaves of “Otaki-turnip” in Kiso district – is eaten with rice and in miso soup. The Otaki-turnip is boiled, inoculated with “Zumi” (a wild small apple) dried Sunki from the previous year and allowed to ferment for one to two months. Micro-organisms involved include Lactobacillus plantarum, L. Brevis, Bacillus coagulans and Pediococcus pentosaceus (Makayama,1957)
Thank you so much for teaching me everything I know about lactic-acid fermentation. Without your help and advice, I would have continued to make unhealthy, moldy, mason-jar "ferments". I appreciate everything you have done for me.
