PURPOSE:To obtain a complex of fibrous material having high strength and hypha-like substance, namely, paper without beating process by growing hypha- like organism in a medium containing fibrous material. CONSTITUTION:Fibrous material composed of synthetic fiber such as pulp, waste paper or polyester or inorganic fiber such as alumina or carbon fiber is prepared. Then, said fibrous material is directly or in slurry state added to a medium suitable for growing of hypha-like organism containing organic and inorganic nutrient (e.g. YM medium in a case of mold) so as fiber content to be 0.05-80%. Next, hypha-like microorganism such as mold (Aspergillus, etc.) or yeast (Candida, etc.) is added to said medium and cultured at a temperature of 5-95 deg.C for 5-10days. As a result, many hyphae are grown from the surface to afford the aimed complex of fibrous material and hypha-like substance. Besides, paper having sufficient strength is obtained by using recovered waste paper as the fibrous material. |
