  • Publication number: 20140113331
    Abstract: Combining controlled open-ocean iron enrichment with a system for collecting the ensuing biological growth can lead to a fundamental shift towards using marine biomass feedstock for large-scale global biodiesel production. The literature review reveals that open-ocean enrichment effectively reduces both the atmospheric carbon dioxide partial pressure and ocean acidity. A semi-closed ocean system is provided that allows for the efficient cultivation and harvesting of a high tonnage biomass feedstock generated by iron fertilization. The concept methodically capitalizes on the ocean's free nutrients, kinetic/potential energy, and expansive surface area to ensure that the mass, energy, and cost balance equations favor our system while taking care to preserve the ocean's ecosystem. The system is modular, portable, easily scalable system, and minimizes waste.

    Abstract: A method produces a chemical through continuous fermentation including: (a) culturing a cell in a culture medium in a fermentor to ferment a feedstock to produce a chemical; (b) conducting filtration of the culture medium with a separation membrane module; (c) separating a permeate containing the chemical from the culture medium while retaining a non-permeated liquid in the fermentor, and (d) supplying a gas from at least one of a lower portion of the separation membrane module and a pipe communicating between the fermentor and the separation membrane module to adjust a gas linear velocity in the separation membrane module to 0.15 cm/s to 70 cm/s while supplying the separation membrane module with a liquid.

  • Publication number: 20130323784
    Abstract: A target substance can be efficiently produced by culturing, in a medium, a coryneform bacterium in which the activity of a PTS protein relating to fructose uptake is reduced or lost as compared with a parent strain and the bacterium can produce the target substance, allowing the target substance to form and accumulate in a culture; and collecting the target substance from the culture
