Abstract: The disclosure is directed to an apparatus and method for recovering ethanol from a fermentation broth. The fermentation broth comprises microbial biomass, ethanol, methanol, ethyl acetate, at least one thiol, and at least one compound having 3 or more carbon atoms. The method comprises separating at least microbial biomass from the fermentation broth to generate a process stream; removing, in any order, from the process stream: ethyl acetate by reacting ethyl acetate with a base compound followed by distillation; at least one thiol by adsorption or reaction to disulfide; methanol by distillation; compounds having 3 or more carbon atoms by distillation; and recovering ethanol by distillation; wherein the distillations may be conducted in a single column or two or more columns.

Abstract: The invention provides animal feed comprising microbial biomass and methods of producing animal feed by culturing a microorganism to produce microbial biomass. In particular, the invention relates to animal feed produced by fermentation of a gaseous substrate comprising one or more of CO, CO2, and H2, especially by a Gram-positive, anaerobic, and/or Clostridium microorganism.

Abstract: The invention provides genetically engineered microorganisms and methods for producing chorismate-derived products, such as para-hydroxybenzoic acid, salicylate, 2-aminobenzoate, 2,3-dihydroxybenzoate, and 4-hydroxycyclohexane carboxylic acid. Typically, the microorganism comprises at least one of (a) an exogenous chorismate pyruvate lyase, (b) an exogenous isochorismate synthase, (c) an exogenous isochorismate pyruvate lyase, and (d) a prephenate synthase comprising a disruptive mutation.
