Fungi
Japanese: 真菌（菌類）
A group of eukaryotic organisms including molds, yeasts, and mushrooms. They have chitin in their cell walls, do not photosynthesize, and are heterotrophs that obtain nutrition by decomposing organic matter.
Fungi is a large group of organisms that includes molds, yeasts, and mushrooms. Though they may sometimes resemble plants, they do not photosynthesize. They are decomposers that obtain nutrition by breaking down organic matter.
Their greatest difference from bacteria is that they are eukaryotes—possessing a nucleus enclosed in a membrane. Their cell walls contain chitin, a substance also found in insect exoskeletons.
In the world of fermentation, koji mold and yeast are the two stars of the fungal kingdom. They look and live entirely differently, yet they are kin.
