    摘要: A method of producing lactic acid by continuous fermentation includes filtering a culture of polyploidy prototrophic yeast having a capacity to produce lactic acid by introduction of a lactate dehydrogenase gene through a porous membrane having an average pore size of not less than 0.01 μm and less than 1 μm; and recovering the lactic acid from filtrate while the unfiltered liquid is retained in or returned to the culture and a fermentation feedstock is added to the culture.

    摘要: To control flow velocity of a culture liquid inside a membrane separation tank without giving influences to culture conditions in the fermentation tank, and also suppress precipitation of microorganisms or culture cells so that the production efficiency of the chemical product can be improved, in a method for producing a chemical product including the steps of: cultivating microorganisms or culture cells in a fermentation tank; transferring a culture liquid from the fermentation tank to a membrane separation tank so as to filter the culture liquid through a separation membrane; and collecting a fermentation product from a filtration liquid as the chemical product while refluxing an unfiltered culture liquid that has not been filtered so as to be joined to the culture liquid on an upstream side of the membrane separation tank, one portion of the culture liquid to be transferred from the fermentation tank is allowed to bypass the membrane separation tank depending on a pressure at the culture liquid flow-in side of the membrane separation tank.

    摘要: A wide bandwidth color video signal, such as a high definition television (HDTV) signal is recorded on a video disc by timebase expanding the luminance component and timebase compressing the color difference components to a bandwidth substantially equal to the bandwidth of the timebase expanded luminance component. The timebase expanded luminance component and the timebase compressed color difference components are time division multiplexed and separated into plural channels of multiplexed signals, each of which is recorded in a respective track on the video disc. Signals recorded in this format are recovered by reproducing the plural channels of multiplexed luminance and color difference components from respective tracks, demultiplexing the timebase expanded luminance component and the timebase compressed color difference components, timebase compressing the separated luminance component to return it to its conventional timebase, and timebase expanding the separated color difference components to return them to their conventional time base.
