The present invention relates to a novel compound tetrahydrocurcumin and a substance containing the same, which are produced from curcumin or a substance containing it as a material. This substance has characteristic properties such as strong antioxidative activity and yellowish color generated from reducing the original color of curcumin. The curcumin is being produced from a Zingiberaceae plant classified into Curcuma longa as a tropical product and is used for a spice and a yellow pigment for curry powder and pickles. The present invention further relates to the production method.

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.

According to this invention, pulps can be produced in high yields while saving energy by previously fiberizing wood chips used as the original material and then treating with a microorganism having a high lignin-degrading activity and a low fiber-degrading activity upon the wood. In addition, new lignin-degrading enzymes produced by a microorganism used in this invention were identified.
