To provide a novel material or composition that is effective in preventing or alleviating dyslipidemia. [Solution] A material or composition containing live or dead yeast cells or yeast hydrolysates for preventing or alleviating dyslipidemia. Dyslipidemia here refers to one or more abnormalities in blood concentrations of LDL cholesterol (bad cholesterol), HDL cholesterol (good cholesterol), and triglycerides (neutral fats). Zygosaccharomyces rouxii or Pichia are preferred as the yeast. The yeast is preferably of food origin and preferably intended for human consumption.

The utility model relates to the technical field of cultivation tools, in particular to a fish-algae symbiotic system which comprises a fish tank, a microalgae treatment system is installed at the bottom of the fish tank and comprises a treatment bin, the treatment bin is communicated with the fish tank through a glass pipeline, and the glass pipeline comprises a water drainage pipe and a water inlet pipe. One end of the drainage pipe is connected with the input end of the fish tank, the other end of the drainage pipe is connected with the output end of the treatment bin, and the two ends of the treatment bin are provided with an inlet filtering assembly and an outlet filtering assembly respectively. According to the fish-algae symbiotic system, through the arrangement of the microalgae treatment system, microalgae can effectively absorb eutrophication substances and wastes in the fish tank, so that the water quality is purified, and the water body pollution is reduced. Microalgae release oxygen in the growth process, sufficient oxygen is provided for fishes in the fish tank, and a natural ecological cycle is formed. The microalgae is one of fish food sources, so that the bait investment is reduced, and the economic cost of fish culture is reduced.

Multi-carbon compounds such as ethanol, n-butanol, sec-butanol, isobutanol, tert-butanol, fatty (or aliphatic long chain) alcohols, fatty acid methyl esters, 2,3-butanediol and the like, are important industrial commodity chemicals with a variety of applications. The present invention provides metabolically engineered host microorganisms which metabolize methane (CH4) as their sole carbon source to produce multi-carbon compounds for use in fuels (e.g., bio-fuel, bio-diesel) and bio-based chemicals. Furthermore, use of the metabolically engineered host microorganisms of the invention (which utilize methane as the sole carbon source) mitigate current industry practices and methods of producing multi-carbon compounds from petroleum or petroleum-derived feedstocks, and ameliorate much of the ongoing depletion of arable food source “farmland” currently being diverted to grow bio-fuel feedstocks, and as such, improve the environmental footprint of future bio-fuel, bio-diesel and bio-based chemical compositions.

A method for controlling invertebrate pests of potato plants comprises the step of contacting the plant, parts of it, its propagation material, the pests, their food supply, habitat or breeding grounds with one or more compound of formula (I), or a composition thereof.

An object of the present invention is to prepare a novel food-derived exosome composition and to provide a cancer inhibitor or an agent for preventing decrease in tissue elasticity or an agent for improving elasticity containing a novel active ingredient. As a result of intensive studies on the purification process, the inventors have found that an exosome can be extracted from yeast mash and moromi by a unique production method. The inventors have found that the exosome recovered from the yeast mash and the moromi has a cancer cell proliferation inhibition ability, an ability to promote increase in the amount of granzyme, and an ability to promote expression of collagen and elastin. Accordingly, the inventors provide a composition for treating or preventing cancer and an agent for preventing decrease in tissue elasticity or an agent for improving elasticity, containing exosomes derived from yeast mash and moromi of sake.

A filter system and filter suitable for water treatment includes a filter having a housing with a water inlet and an outlet, the housing defining a filtration chamber therein. The filtration chamber has filter media therein having a plurality of at least partially porous filtration beads and a pump for pumping water to the inlet. Such a filtration system enables high nutrient removal thus minimising the food source for algae.

This invention relates to the field of food origin traceability technology, and provides a method for tracing the origin of *Porphyra yezoensis* based on mid-infrared spectroscopy and CARS-GA, solving the problems of long processing time and low accuracy in modern food traceability technologies. The method includes the following steps: S1, collecting *Porphyra yezoensis* samples from different aquaculture areas and performing mid-infrared spectral acquisition; S2, preprocessing the spectral data to obtain the average spectrum of each *Porphyra yezoensis* sample; S3, using the CARS algorithm to perform preliminary screening on the average spectrum obtained in step S2 to obtain the first characteristic wavenumber variable; S4, using the GA algorithm to perform secondary feature selection on the first characteristic wavenumber variable obtained in step S3 to obtain the second characteristic wavenumber variable. Finally, 59 key characteristic wavenumbers are accurately extracted from 7468 original variables to obtain an origin traceability identification model. The LDA model achieves 100% identification accuracy.

The invention belongs to the technical field of biological immobilization, provides a preparation method of a multi-scale gridding metazoan carrier for sludge reduction, and aims to realize efficient reduction of sludge by accurately controlling the activity range of metazoan. The multi-scale gridding metazoan carrier adopts a multi-level gridding design, large-scale gridding effectively limits the activity space of metazoan and improves the population density of the metazoan, and small-scale gridding provides a suitable living environment for protozoan and serves as a food source of the metazoan. The design not only ensures the distribution uniformity of metazoan and protozoa, but also promotes the cyclic utilization of nutritive salt and organic matters, thereby constructing a stable ecological chain. Practical application verifies that the carrier significantly improves the sewage treatment efficiency, realizes effective reduction of sludge, and provides a new thought and method for technical progress in the sewage treatment field.

The application belongs to the technical field of aquaculture, and discloses a paste feed for anuran, a supplementary food device, an artificial supplementary food method and application, and the composition and weight parts of the paste feed are as follows: soybean meal 5-10 parts, shrimp powder 10-15 parts, corn starch 5-10 parts, fish meal 10-15 parts, compound vitamin 1-2 parts, and radix astragali extract 1-2 parts. The application solves the problem that anuran cannot open its mouth to feed, and can take semi-solid nutritional substances as food sources. The application avoids the death of anuran caused by diseases or stress and the inability to feed. Meanwhile, the application increases the practicability in the actual operation process by adding an opener device in the supplementary food device, and reduces the influence of human operation on the supplementary food object.
