Processes and systems for recovering products from a fermentation mash. In some examples, a process for recovering products from a fermentation mash can include processing a ground corn product to produce a fermentation mash that can include ethanol. At least a portion of the ethanol can be separated from the fermentation mash to produce a whole stillage. The whole stillage can be separated to produce a fiber rich product and a filtrate. The fiber rich product can be hydrolyzed to produce a saccharification mash. The saccharification mash can be processed to produce additional ethanol and a stillage protein product.

A method for cultivating at least one microorganism of interest, by heterotrophism or mixotrophism, in an aqueous culture medium, contaminating microorganisms developing naturally in the culture medium. A portion of the culture medium with the microorganism of interest and the contaminating microorganisms is sampled. The microorganism of interest and the contaminating microorganisms in the portion of culture medium is physically separated. The contaminating microorganisms thus separated is lysed to produce a lysate. The lysate is reintroduced into the culture medium.

The present application provides a method for lysis or electroporation of cells in a biological sample including the following steps: passing cells of the sample, suspended in a fluid, through a flow path with a preset flow speed, wherein the flow path runs through a detection apparatus for detecting individual cells and wherein the flow path includes at least two electrodes for generating an electric field, which electrodes are located downstream of the detection apparatus and which electrodes are coated with a dielectric material with a relative permittivity greater than 3.9, wherein the coaling at least covers the surface of the electrodes that faces the flow path, and when the presence of a specific cell is detected in the detection apparatus, then an electric field is generated between the electrodes when the detected cell passes between the electrodes in dependence of the flow speed, wherein the electric field causes electroporation or lysis of the cell.

A method of targeted electroporation and/or lysis of eukaryotic cellular bodies in a biological sample with at least two subgroups of eukaryotic cellular bodies, wherein each subgroup has a different susceptibility to electroporation and/or lysis in electric fields, including the following steps: transferring the biological sample in a chamber, exposing the biological sample to an electric field in the chamber, wherein the electric field is generated by at least two electrodes which are coated with a dielectric material with a relative permittivity greater than 3.9, and selecting the electric parameters of the electric field such as the field strength, the frequency or the wave form so that the subgroups are differently affected by said electric field for electroporation and/or lysis; as well as devices for the method.
