Disclosed are materials and methods for managing aerobic biosynthesis. The materials include a fermenter system comprising a fermenter, a microorganism provided to the fermenter, and at least two control loops. The methods are directed to measuring and controlling different oxygen concentrations within the fermenter.

Materials and methods for managing aerobic gas fermentation

The present disclosure generally relates to methods for the recovery of amines from aqueous mixtures. In particular, the disclosure relates to methods for separating amines from amine-containing aqueous mixtures by adjusting the pH of the aqueous mixture relative to the highest pKa value for the amines.

Systems and methods for recovering amines and their derivatives from aqueous mixtures

Provided herein are systems and methods for recycling and supplementing off-gas from a gas fed reaction process. The systems and methods are particularly useful for bioprocesses that convert hydrogen gas into one or more biosynthetic products. By maintaining separate hydrogen and oxygen feed gas streams, and forming a recycle gas that introduces a target component of the supply gas to the bioreactor within a target concentration range, the yields, productivities, and safety profiles of the bioprocess can be enhanced.

High hydrogen utilization and gas recycle

Provided herein are methods for increasing the yield of an extracellular product synthesized by an organism cultured in a continuous aerobic fermentation system. The extracellular product yield is increased through the use of an organism modified to decreased production of polyhydroxyalkanoate, to increase production of the extracellular product, and to include promoters that can be inducible in response to nutrient limitation conditions. The extracellular product yield is also increased by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are non-naturally occurring organisms that have been modified for use with the provided methods, and extracellular products made using the provided methods.

Materials and methods for controlling limitation conditions in product biosynthesis for non-PHB generating species of the generaorand organisms related thereto

The present disclosure describes biocatalytic processes for producing a product, comprising providing an aqueous stream (AS) comprising at least one fermentable substrate and a gaseous stream (GS) comprising at least one of CO/H, H, methane, and/or CO to a fermentation zone, wherein the GS and AS stream are optionally contacted and/or mixed; the fermentation zone comprising at least one organism capable of metabolizing an AS substrate and a GS substrate, wherein the fermentation operates at conditions to mixotrophically metabolize at least one gaseous substrate in the GS and at least one substrate in the AS, producing the product. The present disclosure also describes compositions comprising an AS, a GS, and an organism, wherein the organism or an equivalent or engineered equivalent thereof is a methanotroph or a hydrogen-metabolizing or CO-metabolizing chemolithotrophic organism, and wherein the organism is capable of mixotrophic metabolism of at least one gaseous substrate in the GS and at least one substrate in the AS. The present disclosure also describes a process wherein said fermentation operates at conditions to mixotrophically metabolize at least Hin the gaseous stream and glycerol and lactic acid in the aqueous stream. The present disclosure also describes a system for producing a fermentation or bio-derived product.

Biocatalytic processes and materials for enhanced carbon utilization

Provided herein are methods for generating cellular biomass in continuous aerobic fermentation systems. The biomass yield, and the concentration of polyhydroxyalkanoate within the biomass, are each directed to advantageous levels by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are biomass produced using the provided methods, and animal feed compositions including the provided biomass.

Materials and methods for controlling PHA biosynthesis in PHA-generating species of the generaorand organisms related thereto

Methods, systems and compositions for producing at least one light-boiling, volatile, organic product using at least a portion of one or more carbon containing substances from a non-biosynthetic process in a biosynthetic process are provided. These methods, systems and compositions are useful in reducing waste treatment load of carbon containing chemical process waste streams.

Materials and methods for the synthesis of carbon products from non-biosynthetic processes and streams

The present disclosure provides methods for controlling oxygen concentration during aerobic biosynthesis, e.g., fermentation. The method may comprise feeding an oxygen-containing gas into a vessel including a fermentation feedstock and reacting the fermentation feedstock with the oxygen-containing gas to form a broth including a gaseous phase dispersed within the broth. The gaseous phase may comprise any unreacted oxygen from the oxygen-containing gas. The method further includes reducing the concentration of the unreacted oxygen in the dispersed gaseous phase to less than the limiting oxygen concentration ('LOC') for flammability before separating the gaseous phase from the fermentation broth. The concentration of the unreacted oxygen in the gaseous phase is reduced by employing oxygen removal schemes or oxygen dilution schemes.
