(KR2000073645-A)   NOVELTY - Apparatus for treating organic waste comprises a selector (1) to remove inorganic materials e.g. metal, vinyl and glass, a transport pipe (2), a crusher (3) and a pretreatment tank (5).    USE - For treating organic waste material, water treatment and for making useful substances from the fermentation by-products e.g. enzymes, yeast, microorganisms, manure and provender (claimed).    DETAILED DESCRIPTION - Apparatus for treating organic waste comprises a selector (1) to remove inorganic materials e.g. metal, vinyl and glass, a transport pipe (2), a crusher (3) and a pretreatment tank (5) where organic materials are diluted with water to 6-8 % solid components. The contents of the pretreatment tank are stored at room temperature after being autoclaved, and in every tank or fermenter, the organic waste is agitated by an air provider (18) and agitator (6) to prevent anaerobic fermentation. The liquid organic waste in the pretreatment tank is transported to the primary fermenter (8) through a transport pipe (7) and is fermented by the catabolite repression insensitive mutant strains. The primarily fermented organic waste is then sent to a centrifuge (10) through transport pipe (9) and separated into solids and supernatant. 10-20 % of the supernatant is recycled through a pipe (11) to the primary fermenter (5), and the remaining 80-90 % is transported to the secondary fermenter (12). The solid is discharged through transport pipe (13) and is dried by a dryer (16) to produce manure, provender etc. The culture condition in the secondary fermenter (12) is varied according to the bacterial types.    INDEPENDENT CLAIMS are also included for:    (1) a method of treating organic waste using the apparatus, where the mixture of catabolite repression insensitive mutant strains of Bacillus thermoglucosidasius e.g. BtgMu1 (KCCM-10221), BtgMu2, BtgcelMu1 (KCCM-10220) and BtgcelMu2 are inoculated to improve decomposition efficiency during primary fermentation;    (2) a fermentation method for producing useful substances by using the biodegraded organic material from the fermentation process as standard substrates for secondary fermentation and cultivating high value added microorganisms e.g. yeast, lactic acid bacteria and other strains;    (3) a method for collecting useful enzymes e.g. amylase, cellulase and protease by separating the fermented organic waste solution by centrifuging at 5000-7000 rpm for 10-20 minutes then recycling the supernatant containing bacterial enzymes into the primary fermenter 2-3 times; and    (4) a method for exploiting by-products of fermentation by using the heat generated by the fermentation process and remains from fermentation is applied to manure or provender.
