    摘要: The present invention provides a method for manufacturing organic acid by high-efficiency fermentation, which comprises the steps of continuous culture of organic acid bacteria and collection of organic acid produced from the culture employing a cell-recycle multiple-stage continuous fermentor with serially connected fermentors, each of which comprises a fermentor containing a ferment container, temperature controller, stirrer, and pH controller; pumps for efflux-circulation of media from the fermentor; and, cell separator for separation and circulation of media from the pumps. According to the present method, the high-concentration lactic acid of 90 g/L can be produced with the high productivity of 50 g/L/h, which can reduce the facility cost and production cost in the bulk manufacturing process. In addition, the present invention can be effectively applied to the production of other organic acids such as acetic acid, formic acid, citric acid, malic acid, maleic acid, fumaric acid, and succinic acid, which show the end-product inhibition.

    摘要: A control method for operating aqueous Haematococcus spp., such as H. pluvialis, microorganism growth processes is disclosed which can maintain viable growth conditions of this microorganism which have heretofore not been easily reproduced in commercially valuable quantities. The primary control parameters are the degree of turbulence in the aqueous growth medium and the scale of the apparatus relative to the scale of the turbulent eddies in vessels which are partially filled with the aqueous medium directly affect conditions which are required for optimum growth: light exposure, nutrient supply, sedimentation rate, bulk temperature, gas exchange rate and cell integrity. These control elements can be cast in terms of the Reynolds number (N.sub.re), pH, temperature, amount of impinging light, and NO.sub.2 concentration, depending upon the operative chlorophyll growth stages of Haematococcus spp. and its photoadaptive stages of producing astaxanthin.

    摘要: An apparatus and method for anaerobic and aerobic respirometry. The apparatus and method provide for automatically collecting and analyzing the data required to calibrate mathematical models for bioprocesses that involve anaerobic respiration, aerobic respiration and dehalogenation. Dissolved electron-acceptor concentrations and/or product concentrations and/or headspace pressures are automatically monitored during the progress of a biotransformation occurring in a batch reactor to produce a data set. The data set is analyzed to derive intrinsic kinetic parameters and stoichiometric coefficients. The cultures biocatalyzing the oxidation-reduction reactions of interest may be aerobic, denitrifying (e.g., nitrate-reducing), sulfate reducing and/or methanogenic. The models thus developed may be used for design of wastewater treatment or bioremediation processes.

    摘要: A cell growing device for in vitro cell population growth includes at least one hollow fiber cartridge having a plurality of capillaries at least one of which is selectively permeable. The flow of media out of a lumen of the cartridge is substantially blocked off thereby forcing media flowing into the lumen via an inflow opening to permeate across the capillaries of the cartridge and into the extracapillary space thereof.

    摘要: A process for the removal of ammonium from aqueous liquids, especially from fermentation broths, is disclosed. The process uses a cation exchanger membrane which separates a liquid on a donor side that is to be depleted of NH.sub.4.sup.+ from a solution on an acceptor side whose pH is higher than on the donor side. Because of the equilibriumNH.sub.4.sup.+ .revreaction.NH.sub.3 +H+there is on the acceptor side increased formation of NH.sub.3. This is continuously removed, in particular by reducing the pressure and/or passing through inert gas, or by selective transport through another microporous membrane into an acid protonation solution, so that a NH.sub.4.sup.+ concentration gradient is maintained across the membrane. A similar content, apart from the ammonium concentration, of concomitant cations on the donor and acceptor side and/or a high ratio of the solution volumes on the donor side and the acceptor side ensures that the solution on the donor side to be depleted of NH.sub.4.sup.+, does not lose concomitant ions. A suitable apparatus comprises a flow section which can be coupled into a bypass and has a cation exchanger limiting membrane which is simultaneously a limiting wall of an acceptor chamber. The acceptor chamber may contain devices for pH control and NH.sub.3 removal or these may be contained in a flow section.
