20140141405 | Method for Increasing the Biomass and the Metabolic Activity of Microorganisms by the Combined Adjustment of the Oxidation-Reduction Potential and of the Oxygen Dissolved During the Fermentation Process - The invention relates to a method for cultivating microorganisms, particularly of the type that comprises the step of seeding a culture medium with one or more microorganism strains, and the step of cultivating the medium thus seeded, characterized in that it comprises, during the entirety or a portion of the cultivation, the two following and simultaneous adjustments: adjusting the amount of oxygen dissolved in the medium to a given dissolved-oxygen setpoint; adjusting the value of the redox potential Eh of the medium to a given setpoint value Eh. | 05-22-2014 |
20130247761 | Method and System for Membrane-Based Gas Recovery - A fast gas is recovered from a feed gas containing a fast gas and at least one slow gas using a gas separation membrane. A controller may control a control valve associated with a partial recycle of a permeate gas from the membrane for combining with the feed gas. A controller may control a control valve associated with the backpressure of a residue gas from the membrane. | 09-26-2013 |
