Candida humilis
Species of fungus
Kazachstania humilis (prev. Candida humilis) is a species of yeast in the genus Kazachstania.[3] It commonly occurs in sourdough and kefir cultures, along with different species of lactic acid bacteria (e.g., Limosilactobacillus fermentum, Companilactobacillus paralimentarius, Lactiplantibacillus plantarum, and Fructilactobacillus sanfranciscensis).[4][5][6] K. humilis is the most representative yeast species found in type I sourdough ecosystems. The effects of electric field strength, pulse width and frequency, or pulse shape is significant on the membranes of Candida humilis, but not very noticeable.[7]
K. humilis was separated from C. milleri in The Yeasts (fifth edition) in September 2016,[8] although this is not universally accepted and they are still considered synonymous.
