Definitions
- the invention relates to a method for producing fatty acids or fatty acid derivatives (esters or other derivatives) from oil plants.
- the process of the invention applies in particular to oleoproteinous plants such as rapeseed, sunflower, soybean, crambé ...
- the invention can in particular be used to manufacture bio-fuels (diester), lubricants, phytosanitary adjuvants, detergents ... by transformation of the fatty acids produced.
- oilseed plants as raw material goes through the production of free fatty acids which constitute the raw material for the industries of transformation towards fuels, lubricants ...
- the lipids accumulated by oilseed plants can be transformed into fatty acid by hydrolysis: two processes are currently used industrially to effect this transformation.
- a first method consists in hydrolyzing the lipids after extraction by bringing the extracted lipids into hot contact and under pressure with sulfuric methanol or methanolic potash.
- Another method consists in operating the hydrolysis under similar conditions directly on the ground material of seeds without prior extraction.
- the well-known shortcomings of these methods are as follows: high cost of implementation, infrastructure heavy industrial, polluting character of effluents, production of glycerol as a by-product without market currently.
- the present invention proposes to provide a new solution to the problem of the production of fatty acid from oil plants. It aims to provide a solution whose implementation costs are considerably lower compared to known processes (both industrial chemical processes and laboratory enzymatic process).
- An objective of the invention is thus to provide an industrially exploitable process under mild conditions of temperature and pressure, which benefits from a simple and non-polluting implementation, uses a light infrastructure and does not lead to any sub - troublesome product.
- Another objective linked to the previous one, is to make it possible to multiply the fatty acid production installations with a view to bringing them closer to the places of cultivation of oilseed plants and thus to achieve savings in transport of the raw material.
- the process according to the invention for the production of fatty acids or derivatives of fatty acids from oil plants is characterized in that: oil plants are produced PCI7FR95 / 00957
- transgenics having, on the one hand, at least one gene coding for a lipase enzyme, called the lipase gene, on the other hand, associated with this lipase gene, a promoter allowing expression of said gene either in cellular, extracellular or tissues different from those where the lipids of the plant accumulate, either on exogenous induction,
- the seeds or fruits containing the lipids of the said plants are collected, - the said seeds or fruits are ground, where appropriate after inductive treatment, so as to bring the lipids and the lipase contained in the said seeds or fruits into contact,
- the fatty acids from the hydrolysis are extracted or transformed to obtain the desired fatty acid derivatives.
- the process of the invention is an enzymatic hydrolysis process which benefits from the advantages of this type of process (gentle conditions of implementation, absence of pollution, light and inexpensive installations, absence of annoying by-products).
- the plant is caused to produce itself the enzyme necessary for the subsequent transformation of the lipids, while preventing this enzyme from coming into contact prematurely with the lipids so as to eliminate any risk of self-degradation of the plant. before harvest.
- Hydrolysis is then obtained without the addition of exogenous enzyme by bringing the lipids and enzymes produced by the plant into contact.
- Such a method has a particularly low overall cost of implementation.
- the crushing and incubation facilities are light and common in the agricultural environment, so these operations can be carried out at the plant harvesting sites.
- transgenic plants are obtained by initially carrying out the genetic transformation of a natural oleaginous plant, by causing the genetically transformed plant to multiply by the sexual way for the production of transgenic seeds and then using these seeds to obtain descendant transgenic plants.
- the initial genetic transformation consists, according to a currently well-known process, of producing an expression cassette comprising the lipase gene and the expression promoter of this gene and of introducing this expression cassette into the genome of the plant.
- the promoter associated with the lipase gene is adapted to avoid premature contact of the enzyme and the lipids; this promoter can be of several types: it can either (1) direct the expression of the gene in compartments different from those where lipids accumulate, or (2) initiate the expression of the gene at the appropriate time by exogenous induction.
- (1A) either an expression cassette comprising a lipase gene and a promoter controlling the expression of this gene in a cell or tissue compartment different from the lipid accumulation compartment,
- the promoter used in the expression cassette is of the type which can be controlled exogenously by physical, chemical or biochemical signals, in particular a stress promoter controlling expression on application of a physical trauma to seeds or fruits.
- the genetic transformation of the plant is carried out by producing an expression cassette comprising a lipase gene and a promoter controlling the expression of a determined protein from the seed, and by introducing this expression cassette into the genome of the plant so as to cause lipase to be expressed in the compartments of the seed where the abovementioned protein accumulates,
- the promoter of the protein used is advantageously the promoter of napine which allows a massive accumulation of lipase in the protein bodies of the seed, separated from the lipid globules.
- the embodiment 1B above can be used regardless of the type of oleaginous plant, for example by choosing the constitutive promoter 35S of CaMV (Cauliflower mosaic virus) and the addressing sequence PR- S tobacco in order to direct the excretion of the lipases produced towards the extracellular compartments.
- the contacting of lipids and lipases is also carried out in this case by simple grinding.
- the above embodiment (2) can be used regardless of the type of oleaginous plant, for example by choosing the protease inhibitor promoter isolated from the potato, which controls the expression of genes in the event of injuries.
- the inductive treatment which causes the synthesis of lipases can in this case be an action of shelling of the seeds, carried out before grinding.
- a gene coding for a non-specific lipase is used, that is to say characterized by a non-specific hydrolytic activity, in order to obtain a total hydrolysis of the lipids accumulated by the plant and to avoid parasitic saponification reactions.
- lipases with specific hydrolytic activity in order to favor a given type of hydrolysis (for example: monoacylglycerollipase of Peni cylli um camembertii only carrying out the hydrolysis of one of the three bonds of glycerol with fatty acids, for the production of diacylglycerols).
- non-specific lipase genes characterized by the following sequences or by sequences analogous to the following sequences (the arrows mark the coding part): SEQUENCE I ⁇ G'ATGACAACT TGGTTGGTGG CATGACTTTG GACTTACCCA GCGATGCTCC
- Sequence I corresponds to a Rhizopus ni veus cDNA
- sequence II can be isolated from the genome of Pseudomonas aeruginosa
- sequence III from Pseudomonas fluorescens
- sequence IV from Pseudomonas sp
- sequence V from Geotrichu candidum
- sequence VI from Candida cylindracea.
- lipase gene / promoter of expression of this gene into the genome of the oleaginous plant can be carried out by any known protocol.
- this expression cassette can be introduced into the genome of somatic cells of the plant by a transfer using the bacterium Agrobacterium um tumefaciens.
- This introduction into said somatic cells of the plant can also be carried out by another known technique, in particular by electroporation, by biolistics or by microinjection.
- the extraction of fatty acids from hydrolysis is then carried out by any known method, in particular by liquid / liquid extraction using an apolar solvent such as chloroform or hexane.
- the fatty acids resulting from hydrolysis can be methylated in situ by contacting with ethanol in acid catalysis under ultrasound in order to transform them into methyl esters, the latter being extracted by a liquid / liquid extraction using a solvent apolar.
- the present application is intended, as a new product, any oleaginous plant or seed of oleaginous plant, of a variety which cannot be protected by a plant variety certificate, which comprises in its genome an expression cassette having at least one gene coding for a lipase enzyme, associated with a promoter allowing expression of said gene in compartments cellular, extracellular or tissue different from the lipid compartments of the plant or seed.
- the promoter associated with the lipase gene can be a promoter with specific cellular or tissue expression.
- This promoter can also be a constitutive promoter, in which case the lipase gene is provided with an addressing sequence towards cellular or extracellular compartments different from the lipid accumulation compartments.
- the present application also relates to any oleaginous plant or seed of oleaginous plant, of a variety which cannot be protected by a plant variety certificate, which comprises in its genome an expression cassette having at least one gene coding for a lipase enzyme, associated to a promoter allowing expression of said gene on exogenous induction, in particular by stress.
- Rape seeds (Brassica napus, Var Tapidor) are used, which are obtained commercially.
- the seeds are sown in the greenhouse and grown under standard conditions. The health of the plants is rigorously monitored.
- the genetic construction selected involves the promoter of napine, the cDNA of the lipase from Rhizopus ni veus and the terator NOS.
- the napin promoter directs the expression of this protein in a protein compartment of the seed different from that in which the lipids accumulate.
- the whole is introduced into the plasmid pRTI containing the selection gene pa t used to screen the transformants in order to form the construct pRTIL.
- the expression cassette thus obtained is introduced into a plasmid designated "Blue-Script” (trade name) in order to carry out the amplification thereof.
- the amplified expression cassette is then extracted from “Blue-Script” and introduced into a plasmid designated pRT1 which was prepared by grafting the promoter designated CaMV35S onto the 5 'end of the "pat” gene encoding phosphinothricin acetyl transferase (selection gene) and the NOS terminator on the 3 'end.
- a plasmid designated pRTIL containing the targeted expression cassette is obtained. c) Gene transfer and production of transgenic plants
- microspores isolated in a) (10 ° microspores ml- ') are suspended in the medium of Brewbaker and Kwack (JL Brewbaker and BH Kwack, 1963, Am. J. Bot. 50, p. 859-865) containing 13 % sucrose and adjusted to pH 5.9. 50 ⁇ g per ml of the plasmid pRTIL are added to the medium and electrical pulses of 400 V / cm for 10 ms are applied to the suspension using an electroporator "Jouan" (registered trademark) (TRX, GHT) delivering pulses in square wave.
- the culture medium Containing 100 mg / 1 of phosphinothricin is added to the microspores.
- the microspores are cultured in the dark for 24 h at 35 ° C. and then at 25 ° C. After 2 weeks of culture an equal volume of new medium is added and the microspores placed in the light under photoperiod 16 h day / 8 h dark.
- the regenerated plants resistant to phosphinothricin are analyzed in "southern" so as to verify the presence in their genome of the sequence coding for lipase.
- the chromosomal stock of the selected plants is doubled by colchicine (0.1 g / 1 plus a few drops of teepol) and the fertile diploid plants produced are self-fertilized.
- Lipase activity is sought on a limited number of seeds. Plants with seeds with the highest lipase activity are retained and the seeds used for propagation plants until a sufficient seed stock is obtained to carry out the experiments on hydrolysis of the lipids of the seed by endogenous lipases.
- the seeds are ground, the ground material placed in an incubator maintained at a constant temperature of 40 °.
- the ground material is subjected to permanent agitation so as to increase the contact between the lipids and the lipase.
- the fatty acids are extracted with chloroform.
- the chloroform is evaporated and the fatty acids recovered.
