4101 results about "Nutrient" patented technology

A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates, lipids, proteins, and fermentation products (ethanol or vinegar), leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.

The invention discloses a deep-sea microorganism in-situ directional culture device, and relates to the technical field of deep-sea equipment, the deep-sea microorganism in-situ directional culture device comprises a microorganism culture cabin, a nutrient solution storage module, a bidirectional flow path assembly, an intelligent control module, a support assembly and the like; wherein the microorganism culture cabin consists of a flow channel, a flow choking block, a culture chamber, a movable small plate, a cabin cover and a sealing element, and the flow channel and the flow choking block form a structure based on a Tesla valve principle; through a bidirectional flow path assembly composed of a deep-sea high-precision metering pump, a deep-sea flow guide pump and the like, a nutrient substrate is injected in a reverse high-resistance mode to achieve efficient mixing, and seawater flows in a forward low-resistance mode to achieve environmental substance exchange; the deep-sea multi-channel switching valve is independently connected with the multiple sets of nutrient solution storage modules and the microorganism culture cabin, so that culture under various environmental conditions is realized; based on sensor data calculation and analysis, the starting and stopping time of the pump is intelligently controlled, the concentration of nutrient substrates in the microorganism culture cabin and the stability of environmental parameters are effectively guaranteed, and therefore in-situ culture deep-sea microorganism communities are controllable.
