Cell wall polysaccharides in different yeasts species.

Cell wall polysaccharide	S. cerevisiae	K. lactis	S. pombe	D. hansenii	K. marxianus
β-1,3 and β-1,6-glucans	50–65%	50–55%	54–60%	50–60%	50%
α-1,3-glucan	none	none	28–32%	nd	nd
Chitin	1–5%	1–3%	in conidia only	2–7%	1–4%
Mannoproteins	35–40%	30–40%	None	29–35%	20–25%
Galactomannan	None	None	9–14%	None	None

The cell wall components listed were identified from the following sources: S. cerevisiae (Klis et al., 2002), K. lactis (Backhaus et al., 2010; Bahmed et al., 2002), S. pombe (Pérez et al., 2018), D. hansenii and K. marxianus (Nguyen et al., 1998). Results are the means of each component expressed as % of cell wall dry weight. nd = not determined.
