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

Disclosed is a process for preparing adiponitrile from acrylonitrile in an electrolytic cell. An aqueous electrolyte comprising acrylonitrile converts to adiponitrile in the presence of a solid anode and in the absence of a solid cathode. The cathode comprises gas plasma.

Production of adiponitrile

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

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.

Methods for controlling oxygen concentration during aerobic biosynthesis

Nutritive compositions containing an organism having attenuated or no poly(3-hydroxybutyrate) production are provided. These nutritive compositions are useful as feed, such as animal feed and feed additives for ruminants, non-ruminants and aquaculture, etc. Materials and methods for production of these organisms are provided.

Process for separation of diamines and/or omega-aminoacids from a feed fixture

The present disclosure relates to methods for separating and purifying a long chain diacid from other long chain diacids, monocarboxylic acids, hydroxyl acids or alkanes by simulated or actual moving bed chromatography.

Purification of long chain diacids

Elevated temperature, gas-phase, catalyzed processes for preparing HCN in which induction heating is used as a source of energy, and novel apparatus for carrying out said processes.

Induction-heated reactors for gas phase catalyzed reactions

Lactams, in particular &#x3b5;-caprolactam, are produced by the hydrolytic cyclization of aminonitriles, in particular 6-aminocapronitrile, in the vapor phase in a plurality of adiabatic fixed bed reaction zones arranged in succession wherein at least a portion of the heat of the exothermic reaction is removed between each of the successive reaction zones. Conducting the reaction in such a manner requires less capital for the reactor itself. It has also been found that the product exiting such a reaction system can be directly fed to a distillation unit without the need of additional cooling or storing.

Process for making caprolactam

Method for making caprolactam from 6-aminocapronitrile that contains greater than 500 ppm tetrahydroazepine and its derivatives (THA) in which the THA is not removed from the method until after the caprolactam is produced.
