TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The fermentation broth or partially processed fermentation broth comprises a microorganism. The microorganism is Escherichia coli.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The microorganism is engineered to: produce the organic product; and include at least one heterologous polynucleotide encoding a protein comprising a fatty acyl reductase, a fatty alcohol forming acyl-coenzyme A reductase, a thioesterase and a fatty acid biosynthetic enzyme. In the method: one of the two distinct phases is a predominantly non-aqueous phase and one of the two distinct phases is a predominantly aqueous phase; and greater than 50% of fatty alcohol(s) are saturated. The method further comprises: separating the at least two distinct phases from each other; and separating the organic product from the predominantly non-aqueous phase. The method comprises saturated fatty alcohol and unsaturated fatty alcohol. The heterologous polynucleotide encoding a protein is a fatty acyl reductase. The emulsion generates the distinct phases in 5 seconds-72 hours. The heterologous polynucleotide is expressed under the conditions to produce a fatty alcohol organic product. The emulsion is demulsified at a temperature of 20-100 degrees C or 25-60 degrees C. The organic product in the predominantly aqueous phase is further purified by centrifugation, liquid-liquid extraction, and/or distillation. The contacting step is continuous. Preferred Components: The emulsion is a reaction mixture, a fermentation broth or partially processed fermentation broth. The fatty alcohol or its mixture comprise: branched fatty alcohols; and straight chain fatty alcohols. The fatty alcohol contains 8-20C, 8-18C, 10-16C, or 12-14C. The volume of demulsifying solvent to emulsion is 10-100 vol.% or 25-60 vol.% of the emulsion. The concentration of organic product in the predominantly non-aqueous phase is 1-50 wt./vol.% or 2-12 wt./vol.%. The demulsifying solvent is a 3-5C-primary, secondary or tertiary alcohol. The alcohol is propanol, isopropyl alcohol, butanol, sec-butanol, isobutanol, tert-butanol, pentanol, sec-pentanol, isopentanol, 2-methyl butanol, neopentyl alcohol, sec-amyl alcohol and sec isoamyl alcohol as a demulsifying solvent.
