Abstract: The disclosure is directed to a method for recovering products from a fermentation broth. The disclosure relates to the use of extractive distillation to recover products which have close boiling points, such as ethanol and isopropanol, from a fermentation broth. In an embodiment, the recovery of product is completed in a manner that minimizes stress on the microbial biomass, such that it remains viable, at least in part, and may be recycled and reused in the fermentation process, which may result in increased efficiency in the fermentation process. The extractive distillation vessel reactor may be used downstream of a distillation vessel. To minimize stress on the microbial biomass the distillation vessel may be under vacuum. The extractive distillation vessel may be used alongside a separation vessel such that the separation vessel is capable of recycling extractive distillation agent.

Abstract: The disclosure is directed to a method for recovering products from a fermentation broth. The disclosure relates to the use of dehydration to recover products which have close boiling points, such as ethanol and isopropanol, from a fermentation broth. In an embodiment, the recovery of product is completed in a manner that minimizes stress on the microbial biomass present in the fermentation broth, such that it remains viable, at least in part, and may be recycled and reused in the fermentation process, which may result in increased efficiency in the fermentation process. The dehydration reactor may be used downstream of a distillation vessel and converts products such as ethanol and isopropanol into ethylene and propylene. The ethylene and propylene can be used to prepare a component of a fuel or can be polymerized. To minimize stress on the microbial biomass the distillation vessel may be under vacuum.

Abstract: This invention relates to a process for producing lipids and amino acids from a gaseous substrate comprising methane and oxygen. The process uses a culture of a methanotrophic microorganism in a liquid nutrient medium. The methanotrophic microorganism can be a Methylomicrobium bacterium and more specifically Methylomicrobium buryatense 5GB1. The lipid products can be in the cellular membrane of the methanotroph and can be extracted in a separate extraction zone.
