5results about How to "Increase unit output" patented technology

The invention belongs to the field of microbial fermentation and the technical field of daily chemicals, and particularly relates to deacetylated sophorolipid as well as a preparation method and application thereof. By using cheap culture medium components and screening out saccharomycetes with high yield of lactone type sophorolipid, the problem that the production cost of the sophorolipid is too high is effectively solved, and the application of the sophorolipid in various fields is promoted; through the step of carrying out enzymolysis on a fermentation substrate in advance, the problems of long single fermentation period, low thallus utilization rate, high energy consumption and high cost of traditional saccharomycetes are solved. A multi-round fermentation circulation system is designed, and bacteria liquid is settled and recycled and then inoculated and fermented, so that thalli are efficiently and repeatedly utilized, the unit yield is increased, the fermentation period is shortened, and the production cost is effectively controlled. The structure is adjusted through a resin modification technology, a final product mainly comprises acetylated sophorolipid, and compared with acetylated sophorolipid and deacetylated sophorolipid, the sophorolipid has better foam stability and sensitive skin repairing effect and is suitable for the application fields of cosmetics, washing care and the like.

The application relates to a plant cultivation device based on turn-by-turn operation, which comprises a cultivation frame with multiple cultivation layers; a seeding mechanism arranged at the first end of the cultivation frame and used for driving the previously stored plant seeds to be put into any one or more of the multiple cultivation layers; and a plurality of conveying belts which extend from the first end to the second end along the length direction of the cultivation frame and are arranged in gaps in the width direction of the cultivation frame and in each cultivation layer, and are used for carrying the plant seeds and serving as the growth base of the plant seeds; wherein the seeding mechanism comprises seeding parts movably arranged in the multiple cultivation layers, the seeding parts comprise a seeding pipe extending along the width direction of the cultivation frame and a buffer bin arranged on the side of the seeding pipe opposite to the conveying belts, wherein the side of the buffer bin away from the seeding pipe is provided with a plurality of seeding openings, and the side of the seeding pipe opposite to the conveying belts is provided with a plurality of discharging holes in a manner corresponding to the seeding openings.

This invention discloses a plant cultivation system, belonging to the technical field of plant cultivation systems. The system includes a cultivation chamber, double-sided supplemental lighting fixtures, multiple cultivation units, and a ventilation system. By centrally arranging double-sided supplemental lighting fixtures within a closed chamber, and layering multiple nutrient return components and multiple inclined cultivation pots on mounting frames on both sides of the fixtures, with the cultivation chambers of the pots inclined towards the supplemental lighting fixtures, and a ventilation system at the top of the chamber, all planting surfaces can receive uniform light and ventilation. Simultaneously, the ventilation system dissipates heat from the lighting fixtures, eliminating the need for additional cooling devices and resulting in lower energy consumption. Compared to traditional flat-layer cultivation, this solution offers higher space utilization efficiency, more efficient use of light resources, complete recycling of nutrient solution, and more uniform overall crop light exposure. Annual yield for the same planting area is significantly higher than traditional methods, while requiring less manpower and lower costs for daily maintenance, making it suitable for large-scale, high-efficiency cultivation.

The application discloses a kind of natural microhabitat mimic eel ecological nest and indoor circulating water integrated aquaculture method, belong to special aquatic facilities breeding field.Ecological nest is modularization detachable structure, from top to bottom includes: upper biological water purification layer, middle layer bionical habitat layer and lower layer pollution collection and flow guide layer, upper biological water purification layer is mixed by diatomite, porous volcanic rock and biological carrier according to 2:1:1, and aquatic plants are planted;Middle layer bionical habitat layer is equipped with graded curved corridor with inner diameter of 8-10mm and 16-20mm;Lower layer pollution collection and flow guide layer is equipped with 1.5° inclined flow guide groove, hollow bottom hole and sewage outlet at bottom, and nest material is biobased composite material made of plant fiber, degradable plastic and diatomite according to 3:5:2.The application realizes habitat, prevents residual killing, water purification, automatic sewage integration, and the survival rate of eels cultured by the ecological nest is 92.3%, the residual killing rate is only 2.1%, ammonia nitrogen is less than or equal to 0.2mg / L, unit output is increased by 42%, and water replenishment amount is reduced by 65%.

The application discloses a culture method for improving the fermentation yield of tacrolimus and belongs to the technical field of tacrolimus production. The culture method for improving the fermentation yield of tacrolimus comprises the following steps: inoculating Streptomyces tsukuba into a fermentation culture medium for fermentation culture to obtain a tacrolimus fermentation liquor; and performing separation and purification on the tacrolimus fermentation liquor to obtain tacrolimus; and adding macroporous adsorption resin into the fermentation culture medium according to the fermentation time during the fermentation process. The method for improving the fermentation yield of tacrolimus controls the carbon and nitrogen source concentration and pH in the fermentation process and supplements macroporous resin, improves the secondary metabolism efficiency, adsorbs tacrolimus in the fermentation liquor through the macroporous adsorption resin, reduces the negative feedback inhibition effect on the secondary metabolism of the production strain caused by high-concentration tacrolimus, and significantly improves the tacrolimus yield.
