The present invention provides a chromatographic separation process for recovering a polyunsaturated fatty acid (PUFA) product from a feed mixture which is a fish oil or which is derived from fish oil, which process comprises the steps of: (i) purifying the feed mixture in a chromatographic separation step, to obtain a first intermediate product; and (ii) purifying the first intermediate product obtained in (i) in a simulated or actual moving bed chromatographic separation step, to obtain a second intermediate product; and (iii) purifying the second intermediate product obtained in (ii) in a simulated or actual moving bed chromatographic separation step, to obtain the PUFA product; wherein an aqueous organic solvent is used as eluent in each separation step; saturated and/or monounsaturated fatty acids present in the feed mixture are removed in the first separation step; the PUFA product is separated from different components of the feed mixture in steps (ii) and (iii); and the PUFA product obtained in the third separation step contains EPA or an EPA derivative in an amount greater than 90 wt %.

A read circuit for an electrical signal produced by a POSFET device is disclosed which comprises a transconductance amplifier (4) connected at its inverting input to the output of the POSFET device (1), at least one neuron (8a, 8b) connected to the output of said transconductance amplifier, said amplifier being adapted to receive a signal from the POSFET device representative of a force or pressure exerted on it and to produce at its output at least one current signal (I.sub.0, I.sub.0+) representative of such force or pressure, the at least one neuron being adapted to receive said current signal and to produce an output signal (12a, 12b) being a pulse train with frequency proportional to said current signal.

This disclosure relates to a method and a system for processing grapes. An example system includes a simulated moving bed (SMB) device configured to receive a feed stream and an eluent stream as inputs and provide an extract stream and a raffinate stream as outputs. The feed stream includes a grape juice, the extract stream includes a high-sugar grape juice, and the raffinate stream includes a low-sugar grape juice. The system also includes fermentation equipment configured to produce a low-alcohol wine from the low-sugar grape juice.

The present invention relates to an improved chromatographic separation process for purification of a polyunsaturated fatty acid (PUFA) product and derivatives thereof. In particular, the present invention relates to a particularly efficient chromatographic separation process that employs silica having particular physical characteristics as an adsorbent phase for purifying a PUFA or derivative thereof from a feed mixture.

Systems and devices for producing biological products and methods of using the same are provided. An example universal skid includes a rigid support and a plurality of flow-channel hardware sets. Each flow-channel hardware set couples with a respective flow channel of a plurality of flow channels for unit operations. The flow-channel hardware sets allow the flow channels to operate in parallel or in series for continuous processing over the unit operations. An example modular assembly includes one or more single-use kits for one or more unit operations and a universal skid coupled with the one or more single-use kits. An example manufacturing system includes multiple modular assemblies coupled with each other allowing continuous processing within each modular assembly, in between the modular assemblies, fully continuous processing across multiple unit operations.

The present invention relates to methods of processing lignocellulosic material to obtain hemicellulose sugars, cellulose sugars, lignin, cellulose and other high-value products. Also provided are hemicellulose sugars, cellulose sugars, lignin, cellulose, and other high-value products.

The present disclosure provides for a process for an equilibrium limited reaction using reactive chromatography unit (RCU) in which a first organic donor reactant (FODR) and a second organic acceptor reactant (SOAR) react to form a product mixture of a first acceptor product (FAP) and a second donor co-product (SDCP). The equilibrium-limited reaction does not produce water. The RCU has separation media to separate the product mixture into a raffinate and an extract. The FODR is in a stoichiometric deficit relative to the SOAR for the equilibrium limited reaction, so that the SOAR acts as the eluent for both the raffinate and the extract, and so as not to produce an azeotrope of FODR and the SDCP in the extract.
