The invention is directed to a method for recovering at least one product from a fermentation broth. The invention relates to the use of a vacuum distillation vessel to recover products, such as ethanol, from a fermentation broth, where the fermentation broth comprises viable microbial biomass, and where the recovery of the product is completed in such a manner to ensure the viability of the microbial biomass. The invention provides for product recovery at an effective rate so as to prevent the accumulation of product in the fermentation broth. To ensure the viability of the microbial biomass, the invention is designed to reduce the amount of stress on the microbial biomass. By ensuring the viability of the microbial biomass, the microbial biomass may be recycled and reused in the fermentation process, which may result in an increased efficiency of the fermentation process.

Process and system for product recovery and cell recycle

The invention provides processes and methods for utilization of carbon dioxide (CO) in the fermentation of a gaseous substrate comprising hydrogen (H) and CO. In particular, the invention allows for the conversion of at least a portion of the COin the gaseous substrate to one or more products, such as ethanol, acetate, and/or 2,3-butanediol.

Carbon capture in fermentation

The invention is directed to a device and associated method for recovering at least one product from a fermentation broth. The invention relates to the use of a vacuum distillation vessel to recover products, such as ethanol, from a fermentation broth, where the fermentation broth comprises viable microbial biomass, and where the recovery of the product is completed in such a manner to ensure the viability of the microbial biomass. The invention provides for product recovery at an effective rate so as to prevent the accumulation of product in the fermentation broth. To ensure the viability of the microbial biomass, the invention is designed to reduce the amount of stress on the microbial biomass. By ensuring the viability of the microbial biomass, the microbial biomass may be recycled and reused in the fermentation process, which may result in an increased efficiency of the fermentation process.

The invention relates to the production of products such as alcohols and acids by microbial fermentation, particularly microbial fermentation of substrates comprising CO. It more particularly relates to methods and systems for improving efficiency of products by microbial fermentation. In particular embodiments, the invention provides a method of optimizing production of desired products including the step of ascertaining the proportion of CO converted to CO2.
