In one aspect, the present disclosure provides a method for separating a target component in a fluid sample, which method comprises: a) passing a fluid sample that comprises or is suspected of comprising a target component and cell aggregates through a microfabricated filter so that said target component, if present in said fluid sample, is retained by or passes through said microfabricated filter, and b) prior to and/or concurrently with passing said fluid sample through said microfabricated filter, contacting said fluid sample with an emulsifying agent to reduce or remove said cell aggregates, if present in said fluid sample.

A cell-capturing device includes: one or more introduction channels for introducing test liquid containing cells or treatment liquid for treating the cells in the test liquid into the inside thereof; a discharge channel for discharging the test liquid or the treatment liquid to the outside; a filter having a plurality of through-holes formed in a thickness direction, and being disposed in a channel between introduction channel and the discharge channel so that the test liquid or the treatment liquid passes through the through-holes; an introduction region formed between the filter and the introduction channel in a channel between the introduction channel and the discharge channel; a discharge region formed between the filter and the discharge channel; and a housing part accommodating at least a part of the introduction channel, the introduction region, and the discharge region therein, wherein the cell-capturing device further includes a pre-treatment part formed at a position apart from a connection part with the introduction region on at least one of the introduction channels, and formed by a spatial region having a diameter larger than that of the introduction channel.

A method for producing astaxanthin incorporates a method for producing astaxanthin-rich algae cells and a method for extracting astaxanthin therefrom. An initial feedstock comprises healthy algae, water, and nutrients. During a growth phase, carbon dioxide and light from a light source are supplied to the feedstock, thereby amplifying the algae. At least a portion of the nutrients remaining after amplification of the algae are separated from the amplified algae. During a stress phase, carbon dioxide and light are supplied to the amplified algae, thereby promoting production of astaxanthin by the amplified algae. The amplified algae and a cover are placed within an interior of an attrition mill having interior surfaces and media which are substantially non-reactive to astaxanthin and milled to release the astaxanthin from the algae. The cover limits oxidation of the released astaxanthin.
摘要:
A methane fermentation system which can efficiently generate methane gas is provided. The methane fermentation system (1) decomposes an organic waste (2) with an anaerobic microorganism to cause methane fermentation so as to generate the methane gas (3). The methane fermentation system (1) includes a wet bead mill (4) which finely pulverizes the organic waste (2). The methane fermentation system (1) also includes a methane fermentation chamber (6) in which the organic waste (2) finely pulverized in the wet bead mill (4) is decomposed with the anaerobic microorganism to cause the methane fermentation so as to generate the methane gas (3) . The organic waste (2) is finely pulverized in the wet bead mill (4) in a state where a moisture content is adjusted such that a solid content is equal to or less than 10%. The organic waste (2) whose moisture content is adjusted in this way is finely pulverized such that a particle diameter at 50% in a cumulative distribution with respect to the volume is equal to or less than 20 µm.
摘要:
It is an object to achieve a closed system that has a simple structure without resorting to large scale equipment and that sequentially carries out all of the step of separating useful cells, the step of culturing the useful cells separated in the separation step, and the step of washing and concentrating the cells cultured in the culturing step and to enable the preparation of useful cells having high safety and quality, while improving operability. A disposable set for cell culture includes a cell culture container (CC) having a liquid inlet (Lin) and a liquid outlet (Lout), a cell separation kit (A) that is for separating cells used for cell culture and is connected to the liquid inlet (Lin), and a cell collection kit (B) that is for washing and concentrating cultured cells in the cell culture container (CC) and is connected to the liquid outlet (Lout), and a cell culture device uses the disposable set for cell culture and includes flow path on-off valves and pumps provided at appropriate positions of pipelines of the disposable set and a controller controlling them.
摘要:
By providing a pre-processing unit 20A on a processing liquid channel included in a cell capturing apparatus 100, air bubbles accumulate in an introduction region 24 inside of the pre-processing unit 20A and thus the air bubbles are removed while a processing liquid moves through the introduction region 24 and a discharge region 26, even when the air bubbles are contained in the processing liquid. By providing a foreign matter removal filter 23, at least a part of foreign matters (foreign matters that cannot pass through through-holes 21) contained in the processing liquid can be captured and thus the processing liquid from which the foreign matters are removed can be supplied to a cell capturing device 1 at the subsequent stage. Consequently, the supply of the processing liquid with air bubbles mixed toward the vicinity of a filter 57 of the cell capturing device 1 disposed at the stage subsequent to the pre-processing unit 20A is reduced. This allows the process of cell capturing to be carried out with good repeatability.

Cells in a test liquid are captured and observed easily and accurately. A cell capture filter 30 is fixed by a first protrusion part 125 of a lid member 100 and a second protrusion part 225 of a housing member 200 in a cell capture device 1, and a first fitting part 130 and a second fitting part 230 are fitted with each other. This allows the cell capture filter 30 to be fixed between the lid member 100 and the housing member 200 in a state where a filter region of the cell capture filter 30 is surrounded by the looped first protrusion part 125 and the looped second protrusion part 225.
摘要:
The invention relates to a filtration system for use in a method of determining the presence and/or amount of cells, for example, viable cells, in a liquid sample, and to methods of using and manufacturing such a filtration system. The filtration system includes a cup with an upper portion and a ring portion, where the ring portion is separably coupled to the upper portion.
