A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

An object of the present invention is to provide a microorganism that efficiently produces EPA and a method for producing EPA using the microorganism. The present invention relates to a microorganism having an ability to produce docosahexaenoic acid (DHA), wherein the microorganism contains a protein composed of an amino acid sequence in which at least one of the amino acid residues at positions 6, 65, 230, 231, and 275 in the amino acid sequence represented by SEQ ID NO: 2 has been substituted with another amino acid residue (mutated OrfB), and is capable of producing eicosapentaenoic acid (EPA), and the like.

The present disclosure relates to hydrogels composition comprising protist cells. In particular, the present disclosure relates to hydrogel compositions which may be used to encapsulate or suspend ciliated protist cells, and methods of preparing the same. The present disclosure further relates to methods of infecting molluscs with a ciliated protist cell, and methods and compositions for stabilising ciliated protist cells.

The present invention describes methods of identifying high-risk populations or individuals who have positive serology for T. gondii. These methods include obtaining a biological sample from a subject; determining the level of T. gondii cyst antigen antibody in the biological sample; and characterizing the biological sample in at least one of three categories.

Provided is a dried powder of microorganisms, which is highly suitable for processing and has excellent usefulness as one component of various products. The present invention provides: a dried powder of microorganisms, the dried powder exhibiting a brightness of 55 or more and a chromaticness of 18 or less; and a method for producing a dried powder of microorganisms, the method comprising: washing microorganisms at least once with a liquid having an osmotic pressure lower than that of a liquid culture medium for culturing the microorganisms; and drying and heating the microorganisms after the washing to thereby obtain the dried powder of the microorganisms, which exhibits a brightness of 55 or more and a chromaticness of 18 or less.

One aspect of this disclosure is a method for maintaining a plankton population in a culture medium by removing particles from the culture medium. The method may comprise rotating a filter body to lift the particles from the culture medium with a filter of the filter body, positioning the filter relative to a conduit so that a first portion of the lifted particles fall into the conduit, directing a removal fluid toward the filter body to move a second portion of the lifted particles off the filter and into the conduit with impact forces applied by the removal fluid, and/or outputting an effluent flow from the conduit. The effluent flow may comprise the first and second portions of the lifted particles and a portion of the removal fluid. Aspects of related apparatus, methods, and systems also are disclosed.
