WebAt Leuven Schwann observed the formation of yeast spores and concluded that the fermentation of sugar and starch was the result of life processes. In this way, Schwann was one of the first to contribute to the germ theory of alcoholic fermentation, later elucidated by French chemist and microbiologist Louis Pasteur. Web21 Mar 2024 · The Schwann cells, also known as neurolemmocytes, are a type of glial cells present exclusively in the peripheral nervous system. They develop from precursors in the neural crest and can be differentiated into two types of cells: The myelinating Schwann cells form a myelin sheath around a segment of the axon of a single nerve. This is different ...
