Definitions
- the invention relates to an improved process for the immobilization and drying of proteins, in particular of enzymes, in particular of lipases.
- Prior Art EP382767 describes a process for the immobilization of lipases.
- an aqueous solution of a given lipase is mixed by rotation with a resin (for example Lewatit®) at a fixed pH at room temperature.
- a resin for example Lewatit®
- the immobilized lipase resin was collected by filtration, followed by washing with water and drying in vacuo.
- the immobilization of enzymes is generally accompanied by loss of enzyme due to unbonding to the carrier or by desorption ("bleeding") of already bound enzyme
- the immobilized enzyme often undergoes a loss of enzyme activity due to the immobilization steps, which is precisely the case technical scale leads to significant yield losses and thus increased costs.
- the invention therefore an object of the invention to provide a method that allows to achieve efficient immobilization of the protein to the carrier, which means that as possible lent the entire amount of the enzyme present on the carrier is permanently bound and remains and that im In the case of an enzymatically active protein after immobilization, the same high enzymatic activity as possible is obtained as before immobilization.
- a process has been found for the immobilization of proteins on a carrier, characterized in that the incubation of the protein with the carrier takes place in an aqueous phase in a discontinuous contact vacuum mixer dryer and immediately thereafter optionally after an optional washing step, the drying of the immobilized protein in It has now been found that the method defined at the outset leads to particularly advantageous results, since the entire steps of immobilization, such as efficient incubation of protein with carrier, optionally washing of the immobilized protein and drying of the immobilized protein to a stable , good storage and transportable product in a single apparatus are to be carried out.
- This method is particularly well suited on an industrial scale when immobilized protein is to be produced in the three-digit kilogram to the ton scale. With the method according to the invention a multiplicity of proteins can be immobilized. It is particularly suitable for the immobilization of enzymes, such as oxidoreductases, hydrolases, isomerases and transferases.
- hydrolases in particular of lipases.
- CALB-derived lipases are lipases that have at least one, preferably two or more, amino acid changes, such as insertions, deletions or substitutions, to the CALB polypeptide sequence.
- lipases which are structurally derived from CALB are described in WO 2009/080676 ("CALB muteins"), reference being made expressly to WO2009 / 080676 with regard to the disclosure of the CALB muteins.
- the enzymes to be immobilized can be isolated from the original organism by known methods or also prepared by recombinant DNA techniques in suitable host organisms such as Bacillus, E. coli, Pichia, Chrysosporium, Aspergillus, Saccharomyces.
- Suitable carriers are various organic or inorganic materials such as silica gel, activated carbon or polymer carrier.
- macroporous crosslinked polymers having a particle size of 100 to 1000 ⁇ m and an average pore radius of 10 to 20 nm are suitable.
- macroporous crosslinked acrylate polymers such as, for example, poly (meth) acrylates which are crosslinked with divinylbenzene, which may comprise, for example, acrylic acid, acrylic acid esters, methacrylic acid and methacrylic acid esters.
- Such polymers are sold, for example, by the company Lanxess under the name Lewatit® VP OC 1600 or by the company DOW under the name Amberlite® XAD-7.
- Suitable discontinuous contact vacuum mixer dryers are known to the person skilled in the art from the literature (eg Friedrich Kneule, Das Drying ", Sauerland AG, Aarau, 1975, ISBN 3-7941 -0429-3.) Particularly advantageous is the use of a vacuum tumble or double cone dryer.
- Taumeltrockner are well suited with an inner volume of greater than 10 liters, preferably greater than 100 liters, preferably greater than one cubic meter.
- the incubation of the protein to be immobilized with the carrier takes place in an aqueous phase, which is generally adjusted by buffer to a specific pH.
- the enzyme-containing starting solution is separated from the immobilized enzyme. This is most easily done by filtration through a sieve plate mounted in the tumble dryer. If desired, the immobilized enzyme can then be further purified in a washing step. Such washing steps are also carried out by mixing the immobilized enzyme with the washing solution, usually water, and then separating the immobilized enzyme via an integrated filtration device.
- the subsequent drying of the immobilized enzyme also takes place without further transfer in the discontinuous contact vacuum mixer dryer, wherein a negative pressure in the dryer of less than 1013 mbar, preferably less than 100 mbar is set.
- the jacket temperature is set to less than 100 ° C., preferably less than 65 ° C., care being taken that the product temperature does not exceed a value of 50 ° C., preferably a value of 40 ° C.
- the temperature of the immobilized enzyme it is not recommended to set the temperature of the immobilized enzyme to be dried above 50 ° C in order to avoid thermal inactivation of the enzyme. In cases of particularly temperature-insensitive enzymes, however, can be dried at over 50 ° C.
- the drying time under the conditions given above is usually between 10 and 30 hours, preferably between 15 and 20 hours.
- the aim is generally an immobilized product having a residual moisture content of less than 5%, preferably less than 2% and more preferably between 0.5 and 1.5% water.
- a product prepared by the process according to the invention is readily storable at room temperature without significant loss of activity. Furthermore, it is easy to handle, i. it is easy to transfer and transfer. More specifically, the new method is described in the following example.
- the tumble dryer T0055 used for this process has the following technical data:
- the tumble dryer was rotated once every hour once an hour to avoid the formation of chunks
- the internal temperature has a temperature difference of 5 ° C, depending on whether the tumble dryer is rotating or if the sensor is submerged in the solid
- the dryer was positioned with the slider down
- Big Bag No. 67291 120 hung on the filling device and inflated with N 2 and grounded exhaust air at filling device half open
- TBU Total volatilestrogenicity
- US [%] [g / L] protein
- the infra-red balance was used in a triple measurement to determine the mean dry content of the sample taken from the filled big-bag.
- the measurements gave the following result (infrared balance, end point: 30 sec. Balance standstill, triple measurement: 5.3 g / 9.3 g / 4.6 g):
- the mean dry content of the bottled product is 99.1 1%. This in turn corresponds to a residual moisture content of 0.89%.
