Definitions
- the present invention relates to a method for inducing the intracellular production of stress proteins in plant material, high-quality feed and / or pure stress proteins being obtained.
- Heat stress proteins also known as HSPs
- HSPs Heat stress proteins
- the main stress proteins are divided into four families, namely HSP 90, HSP 70, HSP 60 and a low-molecular HSP family.
- the most important members of the low-molecular HSP family are HSP 45, HSP 20 and HSP 17.
- WO 00/70931 describes a method for producing stress proteins from plant material, the plants being harvested and heated immediately before and / or during and / or after harvesting in order to increase the production of stress proteins in the plant material induce.
- the heating can take place by introducing the vegetable material into closed containers, as a result of which the vegetable material changes the endobiochemical processes are heated, or can be carried out using a radiator or blower.
- the solution to the problem is a method comprising the steps of a) providing plant material, b) introducing the plant material into a liquid medium at a temperature suitable for inducing stress proteins, and if necessary c) separating the plant material.
- vegetable material includes both plants and seeds as well as harvested vegetable material of all kinds.
- the vegetable material is harvested in step a) to provide the vegetable material, preferably before flowering.
- Aquatic plants, algae, soybeans, grass, cereals and / or alfalfa are preferably used as the vegetable material.
- the vegetable material is preferably grown within 10 to 120 minutes, most preferably between 30 and 60 minutes. introduced into the liquid medium in an uncrushed form according to step b).
- the liquid medium is preferably water, which can be mixed with other stressors.
- the temperature of the liquid medium and possibly the additional stressors are suitable for inducing the production of stress proteins in the plant material.
- the temperature of the liquid medium should preferably be about 30 to about 55 ° C.
- the duration of the induction is preferably between about 10 minutes. and about 300 minutes, preferably between 30 and 120 minutes.
- the temperature can either be preset, or it can be increased or decreased at variable time intervals. This results in different induction times and thus different heat stress reactions in the plants or parts of plants, which in turn lead to different HSP synthesis profiles.
- the temperature of the induction bath can be increased uniformly from 25 ° C up to 55 ° C over the induction period. For example, this temperature increase can take place over a period of 30 to 60 minutes. during the entire induction period.
- Induction with an alternating bath has also proven to be advantageous, the first induction bath having a temperature of up to 55 °, preferably around 40 ° C. and a second induction bath having a temperature of between 25 ° and 30 ° C. and the plants or plant constituents first for about 10 min. exposed to the first induction bath, then about 15 min. the second induction bath and then again up to 180, preferably 90 to 120 min. the first induction bath.
- the vegetable material is heated uniformly, in contrast to the previously known method, whereby the uniform heating can be supported by a circulation system in the induction bath with a vertical flow direction.
- the plant material can be exposed to additional chemical and / or physical stressors before, during and / or after, preferably during, step b). Lack of light, electromagnetic fields and UV radiation can be used as additional physical stressors.
- High salt concentrations, alcohols or heavy metal ions, preferably copper ions, aluminum ions, zinc ions, can be used as additional chemical stressors.
- the stress on the living plant cell is increased, the production of the stress proteins is additionally induced and the heating time in the induction bath is shortened after the change in protein synthesis in the cell, which takes about 10 minutes.
- the plant material can be exposed to activators which stimulate the plant metabolism before, during and / or after, preferably during step b).
- nutrients such as CO 2 and trace elements as well as fertilizer can be added to the induction bath to supply the living plant material or the plant material is additionally exposed to a low-energy ultrasound load.
- the activators stimulate the metabolism of the cells, which in turn increases the production of the stress proteins during the influence of stressors inducing the production of the stress proteins.
- the plant material is advantageously introduced into the liquid medium in a dip tank.
- the vegetable material can also be introduced into several plunge pools in succession at different temperatures.
- the plant material can be introduced into a cooled liquid medium, preferably water, in order to slow down or even completely prevent the absorption and auto-degradation of the induced HSP before further processing.
- step c) the vegetable material is separated from the liquid medium.
- the separation can preferably be carried out by introducing the vegetable material into a centrifuge.
- the plant material can be placed in a vacuum drying chamber.
- the temperature in the vacuum drying chamber is preferably about 4 ° C., which is preferably achieved by additional heating of the material to be dried by infrared radiation. Since the plant material is preferably not comminuted and therefore living cells are contained in the plant material, a final induction of the production of stress proteins by cold, lack of oxygen and / or ice formation on the plant material is brought about when introduced into the vacuum drying chamber.
- the vegetable material can additionally be crushed and pressed, the pressing being carried out in particular in such a way that "loose" press cakes are obtained, and the temperature during the pressing process is clearly below 95 ° C., preferably below 45 ° C is held.
- the feed according to the invention is preferably packed in airtight bags under nitrogen or vacuum, so that preservation with chemical preservatives is avoided.
- the feed according to the invention has a residual moisture content of ⁇ 10% and contains about 0.5 to about 50 g of stress proteins per ton of feed. It is therefore ideally suited as an additional feed for animals, since HSPs given orally also stabilize the immune system in animals.
- a plant according to the invention for producing feed containing HSP will preferably enable a throughput of one to four tons per hour.
- seeds, duckweed or algae are used as the plant material.
- the seeds are preferably germinated without light prior to use in the method of the invention. This has the advantage that no chlorophyll and practically no Rubisco are formed, which would have to be separated off later when high-purity HSP was obtained.
- the algae or duckweed can preferably be propagated with optimal nutrient supply and slight temperature stress at temperatures between about 25 to about 35 ° C. and optionally with low-energy ultrasound treatment before being exposed to the induction bath or baths.
- steps b) and c) are carried out in accordance with the embodiment described above, the vegetable before the material after step c) is preferably not introduced into a vacuum drying chamber.
- the vegetable material separated in step c) is then further processed by cutting and grinding.
- the millbase obtained is then subjected to microfiltration, such as pressing using a membrane with 150 kDalton or a ceramic or polymeric hollow fiber of the same pore size.
- the juice thus obtained is subjected to ultrafiltration against an ultrafiltration cascade with 80, 60, 30 and 10 kDaltons.
- the vegetable material is preferably processed further at a temperature of about 2 ° C. in order to avoid the protease, the degradation of the HSP by enzymes.
- the retenates obtained after ultrafiltration are subjected to a chromatography sequence from an ion exchanger and affinity chromatography to isolate the stress proteins contained in the retenates.
- the HSP can also be deposited with a suitable antibody, preferably with a magnetically labeled antibody and separated in a magnetic field or with a suitable surface which binds the antibodies.
- a suitable antibody preferably with a magnetically labeled antibody and separated in a magnetic field or with a suitable surface which binds the antibodies.
- the juice after microfiltration can be used in conjunction with different antibodies to obtain different HSPs, or the residues obtained after the respective ultrafiltration steps can be used.
- High-purity stress proteins are thereby obtained, and the plant for obtaining high-purity HSP can be designed for processing up to 100 kg of plant material, from which, for example, up to 5 g of HSP 70 can be obtained.
