Abstract: The present invention relates to an oil comprising at least one polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA). It is found that LC-PUFA-containing oil are susceptible to gelling by formation of microscopic crystals during storage ultimately resulting in unfavorable quality and handling properties. This problem has been particularly observed with a microbial oil comprising at least about 25% by weight LC-PUFA and a moisture content of 0.2 to 5% by weight. Surprisingly, it has been found that a LC-PUFA-containing oil as described above is effectively stable and does not show gelling properties under conventional storage conditions, if the oil composition as such contains less than about 8% preferably less than about 5% by weight of free fatty acid in the residual moisture of the oil.

Abstract: The current invention relates to a method of isolating polyunsaturated fatty acids containing lipids from a lipids containing biomass. The method involves providing a suspension of cells with a PUFAs-containing lipid; optionally lysing the cells; concentrating the suspension; adding base equivalents to the suspension based on the total dry matter present; feeding a continuous reactor with the suspension; and separating the lipids-containing light phase from the water and cell debris-containing heavy phase.

Abstract: The current invention relates to a method of isolating lipids from a lipids containing biomass with aid of hydrophobic silica and to an oil and to a delipidated biomass as obtained by such a method.

Abstract: The invention relates to the isolation of polyunsaturated fatty acids (PUFAs) from a lipids containing biomass. The main characteristics of the method are that a suspension of cells containing PUFAs is obtained and the cells are optionally lysed. The suspension is concentrated and then incubated for at least an hour at a controlled temperature while adding a specific range of base equivalents to biomass and maintaining a moderate pH. The isolation of lipid may be performed in the absence of organic solvents and without the addition of salt.

The at least one filter membrane has hydrocarbon nanotubes.

Abstract: The present disclosure describes a filter device, e.g., a filter cartridge, for cleaning coolant water for an internal combustion engine. The filter device includes a filter housing defining a housing interior space through which coolant water can flow. An untreated water inlet and a clean water outlet are arranged in the filter housing. A water-permeable separating device divides the housing interior space into a first filtration zone and into a second filtration zone. A first packing material containing activated charcoal for removing dirt particles from the coolant water is present in the first filtration zone, and a second packing material containing hydronium cations and hydroxide anions for demineralizing the coolant water is present in the second filtration zone.

Abstract: A fuel filter device for an internal combustion engine may include a water separator through which a fuel is flowable. To separate water contained in the fuel, the water separator may include a porous and hydrophilic membrane, which may include or be made of polymeric hollow fibers and which may be formed for cross-flow filtration of the fuel. A material of the hollow fibers may be hydrophilized via polyvinylpyrrolidone (PVP). The fuel filter device or the water separator may have a hydrophobic membrane for filtering residual fuel from the water separated via the hydrophilic membrane.
