    摘要: A biodegradable plastic added at an amount of a hydrophilic property imparting-substance providing wettability such that the contact angle of plastic surface to water is 70.degree. or less whereby the decomposability thereof with Basidiomycetes, the cultured products thereof and/or the processed products thereof is improved. A method for decomposing plastic under the conditions with limitation to nitrogen and/or carbon in decomposing such biodegradable plastic. In accordance with the present invention, the plastic which has conventionally been decomposed with difficulty can be decomposed efficiently.

    摘要: The liquid waste after pulp bleaching can be treated by using a microorganism having lignin degradation activity and having been pre-cultured in a culture medium supplemented with the liquid waste after pulp bleaching and/or lignin related substances, the cultured products thereof and/or the treated products thereof.The scarcely degradable colored ingredients and/or chlorinated phenols contained in the liquid waste after pulp bleaching can be decomposed and removed, whereby the efficient treatment of the liquid waste after pulp bleaching can be achieved.

    摘要: A method for measuring a biomass which comprises measuring an electric capacitance across at least one pair of electrodes attached to a bioreactor, and thereby continuously measuring a biomass of organisms (such as microorganism and plant or animal cells), which may or may not be immobilized in the bioreactor, according to the electric capacitance (dielectric permitivity) measured. The present invention permits one to measure on-line the quantities of microorgansisms or plant or animal cells without having to take samples from a bioreactor or culture tank.
