Definitions
- the present invention relates to a method for extracting soluble proteins from microalgae biomass.
- the present invention also relates to the microalgae protein isolates thus obtained.
- chlorella is a potential source of food because it is rich in protein and other essential nutrients.
- microalgae proteins Given their abundance and their amino acid profile, microalgae proteins are thus considered as an alternative source of soy protein or peas in Food.
- the protein fraction can also be promoted as a functional agent in the cosmetic or even pharmaceutical industries.
- these proteins must be extracted from microalgae without impacting their molecular structure.
- an optimized wall disintegration method must for example avoid:
- the cells are agitated in suspension with small spherical particles.
- the breaking of the cells is caused by shear forces, grinding between the balls, and collisions with beads.
- This emulsion is generally atomized and the water is removed, leaving a dry powder containing however a heterogeneous mixture consisting of cell debris, interstitial soluble compounds and oil.
- the difficulty to solve in the use of these cell disruption technologies is the isolation of the only intracellular content (excluding membrane debris, sugars, fibers and fats) and the preservation, inter alia, of the quality protein load.
- the exposure of biological cells to a pulsed electric field of high intensity can indeed alter the structure of the cell membrane.
- the external field causes the loading of the membrane.
- a sufficient transmembrane voltage 0.5-1 V
- the molecular arrangement of the phospholipids changes, which leads to the membrane losing its role as a barrier, making it permeable.
- this membrane permeabilization may be reversible or irreversible.
- This rupture of the membrane then facilitates the release of the cellular contents and, when using a complementary solvent extraction technique, also facilitates the penetration of the solvent into the cell.
- the Applicant Company has found that this need could be satisfied by combining a process of thermal permeabilization of microalgae cells with centrifugation and membrane separation steps (microfiltration, ultrafiltration).
- the present invention relates to a method for thermal permeabilization of the microalgae biomass of the Chlorella genus so as to recover soluble fractions enriched in particular peptides and polypeptides and oligosaccharides.
- the process according to the invention is a process for preparing a protein isolate of the microalgae biomass of the Chlorella genus, comprising the following steps:
- washing the biomass so as to eliminate the interstitial soluble compounds optionally, washing the biomass so as to eliminate the interstitial soluble compounds
- thermal permeabilization of the biomass at a temperature of between 50 and 150 ° C., preferably 100 and 150 ° C., for a period of time between
- microalgae of the genus Chlorella are selected from the group consisting of Chlorella vulgaris, Chlorella sorokiniana and Chlorella protothecoides, and are more particularly Chlorella protothecoides.
- the strain is Chlorella protothecoides
- the strain is Chlorella sorokiniana (strain UTEX 1663 - The Culture Collection of Algae at the University of Texas at Austin - USA).
- Cultivation in heterotrophic conditions and in the absence of light conventionally leads to the production of a biomass of chlorella having a protein content (evaluated by measurement of the nitrogen content N x 6.25) of 45 to 70% by weight. dry cell weight.
- this culture is carried out in two stages:
- the biomass is then collected by solid-liquid separation, by frontal or tangential filtration or by any other means known to those skilled in the art.
- the applicant company then recommends washing the biomass so as to eliminate the interstitial soluble compounds by a succession of concentration (by centrifugation) / dilution of the biomass.
- interstitial soluble compounds means all the soluble organic contaminants of the fermentation medium, for example the water-soluble compounds such as salts, residual glucose, oligosaccharides of degree of polymerization (or DP) 2 or 3 or the peptides.
- This biomass thus purified of its interstitial soluble compounds is then adjusted preferably to a solids content of between 15 and 30% by weight, preferably at a solids content of between 20 and 30%.
- the heat treatment is then carried out at a temperature of between 50 and 150 ° C., preferably 100 and ⁇ ⁇ ' ⁇ , for a duration of between 10 seconds and 5 minutes, preferably for a duration of between 10 seconds and 1 minute.
- This treatment makes it possible to allow the intracellular components to diffuse into the reaction medium.
- the applicant company considers that the heat treatment, performed under these operating conditions, could thus act as a membrane embrittlement process that allows the spontaneous release of soluble components of the intracellular compartment, or even the extracellular matrix.
- organic substances such as carbohydrates (predominantly DP1 and DP2), peptides and polypeptides are drained out of the cell.
- the process according to the invention therefore does not lead to the formation of an emulsion, but to an aqueous suspension.
- a lag time may be necessary to allow sufficient diffusion after the heat treatment which permeabilizes the membrane.
- reaction time between 10 seconds and 5 minutes.
- the residual biomass is then removed by a solid-liquid separation technique by frontal or tangential filtration, by flocculation, by centrifugation, or by any other means known to those skilled in the art, which makes it possible to easily recover the freed soluble fraction. microalgae cells.
- the resulting soluble fraction is ultimately composed essentially of proteins (50-80% w / w) and carbohydrates (5-15% w / w).
- the conventional processes for recovering soluble proteins generally rely on a step of precipitating said proteins with trichloroacetic acid (10% w / v) or with ammonium sulphate.
- the method according to the invention makes it possible, on the contrary, to release native, intact peptides and polypeptides, all of whose functionalities can still be expressed.
- the method of the invention then leads to the isolation of the proteins of interest, by membrane fractionation.
- the applicant company recommends proceeding in two stages:
- recovery and clarification of the soluble fraction thus obtained by microfiltration so as to rid it of the residual insolubles optionally, recovery and clarification of the soluble fraction thus obtained by microfiltration so as to rid it of the residual insolubles, ultrafiltration of the soluble fraction (clarified or unclarified, depending on whether the preceding step of recovery and clarification is performed respectively or not ), on a cut-off membrane membrane of less than 5 kDa, preferably between 1 and 5 kDa, in order to obtain a soluble protein isolate.
- a soluble protein isolate having a protein content of greater than 90% by weight is then obtained.
- the strain used is Chlorella protothecoides UTEX250. Pre-culture:
- composition of the medium (in g / L):
- the incubation takes place under the following conditions: duration: 72 h; temperature 28 ° C; agitation: 1 10 rpm (Infors Multitron Incubator).
- the middle is the following:
- the initial volume (Vi) of the fermenter is adjusted to 17 L after seeding. It is brought to 20 to 25 L in final.
- the driving parameters of the fermentation are as follows.
- the biomass obtained according to Example 1 is:
- the biomass "partially solubilized” thus obtained has of the order of 50% of peptides and proteins (expressed as total amino acids), 20% of sugars and 15% of lipids, corresponding to a solubilization rate between 20 and 50% relatively total initial biomass.
- the "crude” solubles then contain between 60 and 75% of peptides and proteins (expressed in total amino acids - 90% of arginine and glutamic acid), between 10 and 25% of sugars and less than 1% of lipids.
- the “depleted” biomass in the centrifugation pellet still has between 20 and 35% of peptides and proteins (expressed as total amino acids), 25 to 35% of sugars and especially between 20 to 25% of lipids.
- microfiltration permeate "P1" having a solids content of 5% and containing between 60 and 75% of peptides and proteins (expressed as total amino acids) is then ultrafiltered on a membrane of cutoff threshold ⁇ 5 kDa.
- the retentate "R2" ultrafiltration thus obtained has 10% (5 to 20%) of dry matter, and contains more than 90% of peptides with a molecular weight greater than or equal to 5 kDa.
- Permeate "P2" less than 3% dry matter contains for its part peptides with a molecular weight of less than 5 kDa and oligosaccharides of DP less than or equal to 2.
- This "P2" permeate can then be filtered in particular on a reverse osmosis membrane (having a NaCl rejection rate of 93%), so as to obtain: o an "R3" retentate containing more than 10% of dry matter containing peptides having a molecular weight of less than 5 kDa and oligosaccharides of DP 2, such as sucrose;
- the protein isolate "R2" is then:
