Definitions
- the present invention relates to the valuation of co-products of the forestry industry; more specifically, it aims to develop a process improving the digestibility of wood to make it suitable for consumption by mammals.
- the present invention thus also relates to a food having advantageous nutritional properties, especially for farm animals.
- the present invention provides an original process consisting of a sequence of fungal fermentations to make edible woody resources.
- a first fermentation at room temperature with an edible lignivorous fungus for a few weeks makes it possible to obtain a substrate rich in fungal compounds of interest and depleted in lignin. Stopping this fermentation at the optimum time by a suitable process provides a substrate suitable for a second fermentation of a few days by a high added value edible mushroom.
- the product thus obtained contains enzymes and fungal compounds of interest and can be used directly as a dietary supplement.
- Lignin is the second most abundant renewable biopolymer on Earth, and the only source of aromatic carbon generated in nature (on average 20% in hardwoods and 30% in conifers) (Howard, Abotsi, L, & Howard, 2003). Its main functions are to provide rigidity, waterproofness and resistance to decomposition. Lignin is a three-dimensional amorphous polymer composed of methoxylated phenylpropane structures and the isolated lignins generally have a molecular weight of about 2000 to 5000 Da (Wertz, 2010).
- Lignin has several relatively low value-added applications such as:
- the present invention also relates to the product obtained by this process which has remarkable nutritional properties because of its composition of vitamins, minerals, essential amino acids and especially because of its content of high value enzymes for animal feed, especially in xylanases. , amylases and proteases.
- the substrate, or starting material, of the process according to the invention comprises wood residues such as chips (residue size between 1 mm and 2 cm), sawdust (residue size between 1 mm and 2 cm). ), or wood flour (residue size between 20 ⁇ m and 1 mm); depending on the quality of the wood and its digestibility by the lignivorous fungus, the substrate may also include coarser pieces of wood (greater than 2 cm in size).
- wood residues having different sizes for example between 40 and 80% by weight of sawdust and between 20 and 60% by weight of flour. wood possibly in the presence of larger pieces; this difference in particle size promotes a satisfactory aeration of the substrate without the need for mechanical agitation during the first fermentation.
- tannins contribute to the defense system that plants have developed against fungi and limit the digestibility and protein absorption of feed rations (Gilani et al., 2017) (Sharma & Arora 2015).
- the wood residues are mixed with water and heated to a temperature between 50 and 120 ° C, preferably at about 90 ° C; the water is then removed by filtration, for example, on a cellulose filter until a moisture content of between 55 and 70% is reached (Girmay et al., 2016) (Hoa & Wang n.d.).
- the substrate of the first fermentation of the process according to the invention is prepared by adding, to the wood residues, an alkalizing mineral supplement in an amount of between 1 and 5% by dry weight, preferably between 2 to 3% by dry weight, more preferably about 2.5% by dry weight relative to the total weight of wood residues used in the substrate.
- the substrate comprising wood residues and optionally an alkalizing mineral supplement is treated to remove any contaminating microorganisms, or strengthen its alkalizing properties if necessary;
- the substrate is heated before the implementation of the first fermentation; the heating means is chosen by those skilled in the art in particular as a function of the volume of substrate to be treated.
- An alternative pretreatment mode consists in directly treating the wood residues by a gentle heat treatment using the principle of tyndallization with a 60 to 80 ° C core sequence for at least one hour, two to three times in succession at 24 hours. interval, allowing it to cool naturally in the meantime, thereby destroying the vegetative forms of the contaminants and forcing spore germination before destroying new vegetative forms without the possibility of new spomlation; this mild heat treatment is followed by a lactic fermentation to limit the risk of subsequent uncontrolled contamination while remaining in "msmila" conditions (for example with spraying a mixture of bacterial strains of Streptococcus thermophilus and Lactobacillus delbrueckii subsp.
- the whole culture is regrind / homogenized to serve as a basis for the second fermentation.
- This food product also has the advantage of containing essential amino acids at a level of, expressed in mg / g of total protein:
- Another major advantage of the sequential fermentation process according to the invention is based on the use of the fermented product as an immobilization / adsorption support for the secreted enzymes. Indeed, usually, the incorporation of the fermented product into the animal feed requires its stabilization microbiological and enzymatic for the preservation of the product.
- the immobilization of enzymes on insoluble support of organic and inorganic origin is described and pure substrates of carbohydrate nature such as cellulose, starch, agar-agar, alginates have been used (Krajewska 2014).
- the method developed here proposes to use the fermentation product composed of residual lignocellulose and dehydrated mycelium as an immobilization support replacing the traditional supports described above. Surprisingly, the measured enzymatic activity is very well preserved and stable at room temperature after simple dehydration of the fermented product.
- Figure 1 A. First fermentation; growth of Pleurotus ostreatus on sawdust after 40 days of incubation at 28 ° C in the absence or presence of mineral supplement (CM).
- SUBSTITUTE SHEET (RULE 26) ash.
- the activities are expressed in units (pmol product generated / min) / g dry fermented product.
- Figure 9 measurement of laccase activity of the product from the first fermentation (histogram on the left) and that of the product from the second fermentation (right histogram).
- the fermented product is stabilized by dehydration: it is placed after homogenization by mechanical stirring in an enclosure at 24 ° C. until a percentage of moisture of 11-12% is obtained, corresponding to a water activity (a w ) less than 0.6 and preventing the growth of microorganism (Assamoi et al 2009), then it is stored at 4 ° C or room temperature.
- the model chosen for the development of the process was based on the use of coarsely crushed oak sawdust and hot aqueous extraction. After moisture adjustment by filtration and sterilization, the substrate is inoculated with Pleurotus ostreatus and placed for 40 days at 28 ° C to allow the growth of the fungus.
- the growth of Pleurotus ostreatus on oak sawdust could be optimized by adding a naturally available and readily available mineral supplement (ash).
- FIG. 1A shows different culture conditions carried out in the absence or in the presence of the mineral supplement.
- the sequential fermentation process was applied to Aspergillus awamori, a mold of the genus Aspergillus used in the traditional Japanese diet.
- FIG. 6B shows these same residual activities after storage at 4 ° C. of the fermented and dehydrated product for one, two, three and four weeks. No significant loss of activity is observable regardless of the activities measured.
