Present invention disclosed and claimed the method and application of a keratin hydrolysis peptide (“KHP”) solution to promote the growth of wheat under low temperature conditions.
Hydrolyzed keratin has long been used to strengthen hairs, reduce hair splitting and breakage. Other beneficial uses include skin moisturization and wound healing. Keratin hydrolysate has also been known to function as a biofertilizer, boosting plants' growth by enhancing the plants' ability to receive and utilize nutrients, including commonly applied fertilizers.
The KHP solution is made by a hydrolysis process using feathers and water, via a high-temperature and high-pressure process, resulting in a solution that has many beneficial applications in the fields of horticulture, agriculture and potentially other farming businesses.
Among the embodiments disclosed and claimed in this application, one specific embodiment used feathers only, without water, to be treated with the high-temperature and high-pressure process as taught herein to produce a specific version of the KHP solution.
The common wheat plant, Triticum Aestivum, a species of Poaceae, Triticeae plant, is a farming crop originated in Middle Eastern area with fertile soils, and subsequently spread out to Europe and Asia. Up to the year 2023, the top wheat production countries/regions include China, EU, India, Russia, United States, Canada Australia, Pakistan, Ukraine and Turkey, etc.
The wheat plants have two major types: spring and winter species. The winter type is sown around fall season, and will enter speedy growth stage after the low temperature periods in winter and be ready for harvesting in summer. The spring type is sown between March and May, and becomes mature for harvesting in late summer or fall.
For the winter wheat type, while it is able to tolerate the cold weather and go on to the speedy growth stage after winter, if there are low temperature periods in spring season, that may interfere with the germination and proper development of the wheat plants, reducing the photosynthesis capacity.
On conspicuous low temperature injury to the wheat plant, is causing the stem to become brittle, easier to be bent or broken. This leads to maturing wheat crops to stoop or bend down even if the plant is given some normal temperature period to recoup from the injuries caused by low temperature.
There are many undisputed news reports of wheat crop loss due to unpredictable temperature fluctuation, mostly on account of the global climate change. As such, farmers and scientists have been working diligently to come up with solutions for wheat to grow better even under low temperature conditions.
The present invention's KHP solution and the method of using same is a cost-effective way to improve the growth of wheat due to the negative impact of low temperature adversity.
During the seeding stage, the KHP solution can be infused into the soil where wheat are sown. Even in a low light temperature condition, the wheat treated with the KHP solution shows substantially better growth and development than otherwise, sometimes better than the wheat plant that's grown in normal temperature setting.
The inventors of present application conducted numerous tests and confirmed the effectiveness of applying the KHP solution as disclosed and claimed herein.
The keratin solution is primarily based upon feather, which contains 85-91% keratin, 13-15% organic nitrogen, 1.6-2% organic sulfur, as well as other materials. The high keratin content has drawn many prior researches that work to break down, by enzyme, chemical agents, or fermentation process, into peptides, amino acids and other smaller molecules that can be used for animal feeds, plant fertilizers, and cultivation bases.
Around 2019, Nurdiawati, et al, came up with a hydrolysis process, by the mixture of α-amylase and protease to hydrolyze feather waste, resulting in a mixture of amino acids, fatty acids, and sugars. Nurdiawati experimented and adopted certain specific high-temperature and high-pressure setting in the hydrolysis process and discovered that the resulting solution, when mixed with some potassium and other minerals, can boost the growth of Pogostemon cablin and Vigna radiata, as reported in International Journal of Recycling or Organic Waste in Agriculture (8:221-232, 2019).
The inventors of present application, under the aegis of CH Biotech, developed and selected different feather and water compositions to perform the hydrolysis at higher temperature and higher pressure setting, resulting with different keratin hydrolysis peptide (“KHP”) solution that can be used on different crops/plants.
There are different KHP solution embodiments selectable by the inventors based upon mixture of water and feathers, and subject the mixture to a thermal hydrolysis process to create KHP solutions based upon temperature/pressure as defined. One specific embodiment, however, does not use water; the details are shown in subsequent sections of this application.
The inventors used the Dionex UltiMate 3000 UPLC to separate the peptides; an analysis is done via Thermo Orbitrap Fusion Lumos Tribrid Orbitrap mass spectrometry to identify the peptides, which are then subsequently confirmed by looking up the BIOPEP-UWM database.
The solution can be diluted by water, at 30 to 300 times by volume, noted as 30×-300×, with preferred dilution ratios of 50-100 times.
The accompanying drawings, figures and tables, which are incorporated in and constitute a part of this specification, illustrate and exemplify the preferred embodiments of the invention. Together with the description, serve to explain the principles of the invention.
The keratin hydrolysis peptide (“KHP”) solution of present invention can be made by a high-temperature and high-pressure process to treat a mixture of water and feathers.
The selected embodiment in present application contains the parameters as shown below:
The embodiment of keratin hydrolysis peptide (KHP) solution, without water, can be made by 70 kg of feathers, with the feathers' water content being 46%, and then treated by the steps of:
The keratin hydrolysis peptide (KHP) solution of the second embodiment is further filtered and concentrated to 381,250 ppm concentration.
The confirmation of some of the 253 peptides is further done by referencing the BIOPEP-UWM database.
The complete growth duration of the wheat crop is about 120-140 days, depending on species. The whole duration can be divided into five (5) stages: (1) germination, (2) tillering, (3) booting, (4) heading to flowering, and (5) maturity.
Some preliminary fertilizer is given in the early stages (roughly 20-25 days after seeding), to help with early development. Follow-up fertilizers are given around the tillering stage (roughly 2-3 weeks after germination) to boost the tillering and subsequent flowering.
The inventors of present application tested, and confirmed, the effectiveness of KHP solution to combat the adversity of low temperature by infusing into the soil containing wheat plants after seeding.
A normal group of wheat plants are not given the low temperature treatment, thus the “normal group” name. Two experiment groups, 1 and 2, are given the low temperature adversity. Within each experiment group, a check group is not given the KHP solution soil infusion, whereas two experiment groups, A and B, are given the KHP solutions, at different concentration, to compare the effectiveness respectively.
The KHP solutions can be diluted with water, by volume ratio of 1:30-300. In the present application, the inventors preferred the ratios of 1:50 (noted as 50×) and 1:100 (noted as 100×) in several of the tests conducted.
The growth conditions are noted in the table below:
The wheat seeds in all the groups are planted in a regular pot with depth of 3.5 inches and kept in an artificial climate room for cultivation. They are given 16 hours of day time (with light illumination of 35,000 lux) and night time of 8 hours.
For the normal group, the temperature is maintained at 25° C.; 100 ml of water is infused to the soil in each pot starting at seeding time.
Six groups' wheat plants are given low temperature conditions: Low Temp Check 1, Low Temp Exp 1A, Low Temp Exp. 1B, Low Temp Check 2, Low Temp Exp 2A and Low Temp Exp 2B. The day time and night time temperatures are set at 18° C.,
The low temperature treatment to Low Temp Check 1, Low Temp 1A and Low Temp 1B is administered immediately within the first 10 days after seeding. After the low temperature treatment, the wheat plants are placed back into artificial climate room with temperature set at 25° C.
The low temperature treatment to Low Temp Check 2, Low Temp 2A and Low Temp 2B is administered between the 6th to 11th days after seeding. After the low temperature treatment, the wheat plants are placed back into artificial climate room with temperature set at 25° C.
Low Temp Exp 1A and Low Temp Exp 1B are given 100 ml KHP-1 solutions, diluted at 100 times (noted as 100×) and 50 times (noted as 50×) of water by volume at seeding time.
Low Temp Exp 2A and Low Temp Exp 2B are given 100 ml KHP-1 solutions, diluted at 100 times (noted as 100×) and 50 times (noted as 50×) of water by volume at seeding time.
On the 15th day after seeding, the inventors obtain the SPAD readings, tillering counts, above-ground dry weight and under-ground dry weight of the wheat plants in Low Temp Check 1, Low Temp Exp 1A and Low Temp Exp 1B to find out the growth and health status of the wheat plants in different groups.
The chlorophyll instrument (2900PDL, Specturm Technologies) is used to measure and obtain the SPAD reading. The digital scale (AP224X, Shimadazu) is used to measure the obtain the dry weights, both the above-ground and under-ground bio mass. The results are tabulated and reflected in
In
For tillering counts, the Low Temp Exp 1A and Low Temp Exp 1B show 2.2% and 23%, respectively, over that of the Low Temp Check 1 group.
For above-ground biomass dry weights, the Low Temp Exp 1A and Low Temp Exp 1B shows 4.5% and 20%, respectively, over that of the Low Temp Check 1 group.
For under-ground biomass dry weights, the Low Temp Exp 1A and Low Temp Exp 1B shows 11% and 25%, respectively, over that of the Low Temp Check 1 group.
For the tests on the group with low temperature adversity in the seedling stage (6th-11th day), the inventors also took various measurements on the 15th day after seeding. The results are tabulated into
For the SPAD readings in
The inventors confirmed, via the scientific analysis/measurement done, the method of creating the KHP solution and the method of application will help with the growth and root development of wheat plants in low temperature conditions, and will reach the health conditions comparable to those in normal temperature settings.
