Abstract: Asn-linked glycoprotein having antitumor activity, with molecular weight of 32-84 kDa, its producing strain, production and use, adsorbs to Con. A. The process for its production comprises culturing a microorganism belonging to genus Aspergillus and isolating from the culture medium Asn-linked glycoprotein having a molecular weight of 32-84 kDa which adsorbs to Con. A, or a mixture thereof. The substance having antitumor activity is effective for treatment of solid tumors, ascites tumors, multiple cytoma and oval tumors and for the suppression of tumors.

Abstract: The present invention provides a method for processing wastes containing a large amount of water and a method for processing leachate from industrial wastes. Specifically, the present invention provides a method which comprises maintaining reduced pressure in the dryer equipped with a stirring means, feeding wastes containing a large amount of water to the dryer, stirring the wastes while blowing refrigerated air at -20.degree. C..+-.5.degree. C. to the dryer, and drying the frozen moisture portion of the wastes by sublimation. Air heated at 80.degree. C.+10.degree. C. can be used instead of refrigerated air to dry water of the wastes by evaporation. The present invention also provides a method for processing leachate which comprises pooling leachate industrial wastes and burned ashes, and utilizing the leachate to absorb wet-type toxic gas, thereby confining the leachate within the waste treatment plant.
