    摘要： Methods of and system for growing and maintaining an optimized/ideal active yeast solution in the yeast tank and fermenter tank during the fermentation filling cycle are provided. A new yeast stage tank is used between the yeast tank and the fermenter tank allowing yeast to rapidly produce a huge amount of active young yeast cells for a fermenter during the filling period. A measurable and useful controlling factor, %DT/%Yeast by weight ratio (or "food" to yeast ratio), is used (e.g., %DT = glucose), which offers information on the health status of the yeast. The controlling factor is used to control the status of the yeast throughout the entire process.

    摘要： This invention provides optimized fermentation of cellulosic and hemicellulosic sugars. Biomass-derived hemicellulosic and cellulosic sugars are independently conditioned and separately fermented, utilizing reuse and recycle of microorganisms, metabolic intermediates, and nutrients. Conditioned sugars can be fermented in separate vessels, where excess cells from glucose fermentation are conveyed to hemicellulose sugar fermentation along with raffinate from solvent recovery, to enhance productivity and product yield. Some variations provide a method of fermenting C 5 and C 6 sugars to fermentation products, the method comprising: fermenting a C 6 -rich sugar feed to a first fermentation product; fermenting a C 5 -rich sugar feed to a second fermentation product; removing microorganism cells from the first fermentor, to maintain a cell concentration within a selected range; conveying microorganism cells to a second fermentor; and removing microorganism cells from the second fermentor, to maintain a microorganism cell concentration that is greater than that in the C 6 -rich fermentor.

    摘要： This invention provides a way to deal with acetic acid derived from biomass, for fermentation of cellulosic sugars. In some variations, a process for producing ethanol from lignocellulosic biomass comprises: extracting hemicelluloses and acetic acid from lignocellulosic biomass; hydrolyzing the hemicelluloses, using an acid catalyst or enzymes, to generate hemicellulose monomers and more acetic acid; fermenting acetic acid to lipids using a suitable lipid-producing microorganism, thereby reducing acetic acid concentration; fermenting hemicellulose monomers to ethanol using a suitable ethanol-producing microorganism; and recovering the ethanol. The co-fermentation of acetic acid and sugars may be carried out in a single fermentor or in separate fermentors. The invention may be applied to fermentation products other than ethanol. In some embodiments, the fermentation product can act as an extraction solvent to extract lipids from the lipid-producing microorganism, such as a lipid-producing yeast.

    摘要： Continuous processes for the anaerobic bioconversion of syngas to oxygenated hydrocarbonaceous products, in particular lower alkanols, are disclosed in which nutrients, including micronutrients, and lower carboxylate anion are recovered from at least a portion of an aqueous distillation fraction from a distillation unit operation to recover lower alkanols by using a "tight" ultrafiltration membrane. At least about 75 percent of the water permeates the ultrafiltration membrane. The tight ultrafiltration membrane rejects sufficient components that are adverse to the microorganisms used in the bioconversion that continuous fermentation operations over long durations can be achieved.
