Abstract:
A porous absorbent structure of prepared fungal cell wall material, wherein the cell wall material is derived from a fungus selected from the division Zygomycota, the fungus is treated by an extraction with alkali, followed by an acid extraction, wherein the cell wall material is obtained in dry form by subjecting an acid suspension thereof to drying such that the material obtains a porous structure having a net positive charge at pH 7 after reconstitution with water, whereby the dried material has a liquid absorbing property which is at least 30 ml/g of 1% NaCl (aq) and has a liquid transporting ability of water, at a density of 0.01 to 0.03 g/cm3, in a horizontal direction of at least 10 mm during the first minute of absorption and in a vertical direction of at least 5 mm during a first minute of absorption.
