Description
SPECIFICATION
Growth promoting method for basidiomycetes
This invention relates to a method for promoting growth of the fungi of Basidiomycetes by means of cultivation.
Increasing interest is shown recently in use of the fungi of Basidiomycetes as the base material for medicines and health foods, but low rate of growth of such fungi in cultivation thereof as compared with other microorganisms such as bacteria or yeast is causing a bottleneck for industrial utilization of these fungi.
Addition of nutrients such as inorganic salts, extracts from natural products, etc., in the medium has been proposed as a measure for promoting growth of the basidiomycetes in cultivation thereof.
Addition of such nutrients in the culture medium has indeed an effect of promoting cell division of the basidiomycetes, but it can not bring about a similar effect for differentiation of the cells and attendant organization thereof, and hence no desired promotion of growth and propagation is provided. Thus, such measure is unable to realize production of high-quality mycelia of the above-mentioned fungi at a high rate.
We found that growth of the basidiomycetes is markedly promoted and also differentiation and organization of the cells are advanced by adding in the culture medium a small quantity of a straight chain saturated aliphatic alcohol with a carbon number within a specified range, thereby allowing obtainment of high-quality mycelia of the fungi.
The object of this invention, therefore, is to provide a method capable of promoting growth and propagation of the basidiomycetes and producing the high-quality mycelia of the fungi by means of cultivation thereof.
The accompanying drawing is a graphic representation of the experimental results, showing the
relation between the kind of the long-chain alcohol used and the dry culture yield. In the drawing, numbers 1, 2 and 3 represent the results obtained from one-week culture, two-week culture and threeweek culture, respectively.
The invention is described in detail hereinbelow.
The straight chain saturated aliphatic alcohol added in the medium for cultivation of the basidiomycetes according to this invention is represented by the following general formula:
CnH2n + ,OH (I)
wherein n is an integer of 26 to 36. Examples of such straight chain saturated aliphatic alcohol include
the following: n-hexacosanol-l, n-heptacosanol-l. n-octacosanol-l, n-nonacosanol-l, n-triacontanol-l, hentriacontanol-l, n-dotriacontanol-l, n-tritriacontanol-1, n-tetratriacontanol-l, n-pentatriaconfanol-i, and n-hexatriacontanol-l. Most preferred among these alcohols for the purpose of this invention are those having a carbon number of 28 to 32.
It is very interesting to note the fact that, among these alcohols, those having an odd carbon number exist rarely in the natural products but have a growth and propagation promoting action for the basidiomycetes. Most of the long-chain aliphatic alcohols existing in plants, such as n-hexacosanol-l; noctacosanol-l, n-triacontanol-l, etc., are even in their carbon number, and it is reported (Science, Vol.
195, 1339 (1977) and Plant Physiol. Vol. 61, 855 (1978 > ) that, among these long-chain alcohols, ntriacontanol-l alone has a specific effect of promoting growth of higher plants, but there is available no
report on growth activity for the micro-organisms.
Thus among long-chain alcohols, n-triacontanol-l alone has a specific action for promoting growth of higher plants, while all of the long-chain alcohols with a carbon number of 26 to 36 used in this invention have the activities for promoting growth of the basidiomycetes as well as differentiation of the
cells and attendant organization thereof.
The long-chain alcohols represented by the above-shown general formula (I) can produce the
above-stated growth promoting effect for the basidiomycetes by merely adding a small quantity of said
alcohol, or within the range of 0.01 to 10 ppm, in the medium. From the viewpoints of economy and solubility of long-chain alcohol in water, it is advisable to add such alcohol in an amount of 0.05 to 10
ppm in the medium. It is also possible to use a mixture of two or more of the long-chain alcohols.
Although the long-chain alcohols used in this invention can be chemically synthesized, some of
them can be also easily obtained from natural sources through extraction either singly or in the form of a
mixture.
As for the culture medium in which the long-chain alcohol is to be added, there may be used a
wide variety of media which are generally employed for cultivation of the basidiomycetes. For instance,
there may be used the media containing carbon sources such as starch, sucrose, maltose, dextrose,
wood chips, etc., nitrogen sources such as rice bran, wheat bran, corn steep liquor, peptone, broth, meat
extract, soybean flour, powdered cottonseed, yeast extract, malt extract, urea, nitrates, etc., inorganic
salts such as calcium salt, magnesium salt, sodium salt, zinc salt, copper salt, iron salt, manganese salt,
etc., and other nutrients such as vitamins.
The culture medium may be either solid or liquid, and stationary or submerged culture may be
employed in this invention. Addition of the long-chain alcohol into the medium may be made either
before start of the cultivation or in the course of the cultivation after the fungus has grown to a certain
degree.
The Basidiomycetes for which this invention is appliable include a wide variety of fungi that
taxologically belong to the "basidiomycota", but most preferred for use in this invention are the fungi
belonging to the order Agaricales or Aphyllopharales of Homobasidiae, such as for example Armillariella
mellea (Fr.) Karst, Trichloma matsutake (S.l. to et Imal) Sing., Lentinus edodes (Berk.) Sing., Coriolus
versicolor (Fr.) Fuel., Grifila gigantea (Fr.) Pilot, Favolus Arcularius (Fr.) Ames, etc. The taxological
nomenclature of the basidiomycetes is based on "Coloured Illustrations of Fungi of Japan" by ROKUYA
IMAZEKI and TSUGUO HONGO.
The outstanding effect of this invention is not limited to promoted growth of the mycelia of the
basidiomycetes; it also allows obtainment of the mycelia with small bulk specific gravity and advanced
organization in cultivation of for instance Coriolus versicolor (Fr.) Fuel. Further, there are obtained
clusters of mycelia in cultivation of Armillaria Mellea (Fr.) Karst, and the mycelia obtained in cultivation
of Leatiporus sulphureus (Fr.) Bond. et Sing. present reddish orange which is closely analogous to the
color of natural fruit bodies. When Laetiporus sulphureus is cultivated according to the conventional
method, there are obtained light orange colored mycelia.
The histological change of the mycelia in cultivation of the basidiomycetes according to this
invention appears to be based upon with the fact that the long-chain saturated aliphatic alcohol added
in the culture medium is greatly concerned with growth and propagation of the fungi, in view of the
change of phenol oxidase activity, in cultured broth.
The invention is now described in further detail by way of the following examples, but it is to be
understood that the scope of this invention is not limited to these examples.
EXAMPLE 1
Each of 20 ml ethanol solutions dissolved therein 6 mg portions of straight chain saturated
alcohols with different carbon numbers varying within the range of 26 to 36 was added dropwise into 2
litres of water respectively, and after dissolving, ethanol was evaporated to prepare the aqueous
solutions of the alcohols with 3 mg/l concentration each.
The rational formulae and melting points of the straight chain saturated aliphatic alcohols used in
this example are shown in Table 1 below.

1 5 g of yeast extract and 4 g of malt extract to obtain liquid culture media.
Seventy-five ml each of the obtained media was pipetted into 1 5 Erlenmeyer flasks (200 ml capacity), and after cotton-plugged, each flask was sterilized at 1 200C for 1 5 minutes. The medium in each of the Erlenmeyer flasks was inoculated with 0.8 mg of the beforehand prepared seed culture of
Coriolus Versicolor (Fr.) Fuel. (FERM-P No.2,413) and subjected to stationary culture at 250 C. For the sake of comparison, the cultivation was carried out in a medium of the same composition but not added with long-chain alcohol under the same conditions.
After a given period of cultivation, the produced mycelia in the respective flasks were separated, washed well with water, ethanol and acetone and then dried at 60--800C.
The relation between the days of cultivation and the obtained dry culture yield is graphically illustrated in the accompanying drawing.
As noted from the drawing, when Coriolus versicolor is cultivated in the media added with straight chain saturated aliphatic alcohols according to this invention, a sharp increase in yield of mycelia is seen after the 14th day from start of the cultivation, indicating a prominent growth and propagation promoting effect of the straight chain alcohols on the basidiomycetes.
EXAMPLE 2
Cultivation carried out by following the same procedure as Example 1 but by using the aqueous solutions of n-triacontanol-l in concentrations of 3 ppm, 2 ppm, 1 ppm,and 0.1 ppm, respectively, as straight chain saturated aliphatic alcohol.
As control there was similarly performed cultivation in a medium same as said above except that
no alcohol was added.
The results of measurements on change of culture elements with time are shown in Table 2
below.

It is seen from the above table that n-triacontanol-l rather controls growth of mycelia of Coriolus versicolor in the early phase of cultivation, but it comes to show its activity for promoting growth of mycelia visibly from around 14th day of cultivation. It is also noted that the sugar content and reducing sugar concentration in, the used medium and filtrate pH are not much different from those of the control, but the phenol oxidase enzyme activity associated with the intracellular factors changes very specifically by presence of n-triacontanol-l in the medium.
It is to be also noted that the mycelila obtained from cultivation according to this invention were smaller in bulk specific gravity and more solid in tissue than those of the Comparative Examples (control).
EXAMPLE 3
There were prepared the aqueous solutions having dissolved therein n-triacontanol-l in concentrations of 1 ppm, 3 ppm and 10 ppm, respectively, according to the method described in
Example 1, and in each of these solutions (1 litre) were dissolved 60 g of glucose and 7.5 g of yeast extract to form liquid media. For the sake of comparison, there was similarly prepared a medium by dissolving 60 g of glucose and 7.5 g of yeast extract in 1 litre of water but not containing p- triacontanol-l.
One hundred ml each of the thus prepared media including the comparative medium was pipetted into 500 ml Erlenmeyer flasks, and there were prepared 10 incubators for each medium, totailing 40 incubators in all. After sterilization, the medium in each the Erlenmeyer flask was inoculated with 120.8 mg of seed culture of Coriolus versicolor (Fr.) Quél. (FERM-P No.2413) and then subjected to shaking culture at 250C. After 5-day shaking culture, the produced mycelia from the respective cultures were separated, washed, dried and measured in weight. Also, the phenol oxidase activity of each culture filtrate was determined. The results are shown in Table 3 below.

EXAMPLE 4
Twenty-five ml of an ethanol solution containing 7.5 mg of n-triacontanol-l was added dropwise into 2.5 litres of water and n-tiracontanol-l was perfectly dissolved in water. Then ethanol was evaporated away to obtain the aqueous solutions containing n%triacontanol-l in concentrations of 1 ppm and 3 ppm, respectively, and in the thus obtained solutions (1 litre each) were dissolved 60 g of glucose, 3 g of yeast extract, 3 g of malt extract and 5 g of peptone to prepare the liquid culture media.
Fifty ml each of the thus prepared media was pipetted into ten 200 ml capacity Erlenmeyer flasks, and after cotton-plugged, each of the flasks was sterilized at 1 200C for 1 5 minutes.
The media in the respective Erlenmeyer flasks were inoculated with 0.8 mg each of seed cultures of Laetiporus sulphureus (fin) Bond. et Sing. (FERM-P No. 3032)Armillariella mellea Karst. (FERM-P No. 982) and Grifola frondosa (S.R. Gray) (FERM-P No. 3033) and subjected to stationary culture at 25 + 1 OC. For the purpose of comparison, there was conducted a similar cultivation operation by using a medium not containing n-triacontanol-1. After a given period of cultivation, the produced mycelia were separated, washed weii wtth water, ethanol and acetone and dried at 60--800C. The days of cultivation, dry culture yields and indices as determined for the respective mycelia products are shown in Table 4 below.

The above results indicate that n-tir9acontanol-l takes an excellent growth and propagation promoting effect on the above-shown basidiomycetes.
It is to be also noted that the mycelia obtained from the process of this invention are distinguishable in color from those of the comparative examples, that is, in the case of Laetiporus sulphureus, the produced mycelia present reddish orange which is closely analogous to the color of the natural fruit bodies, and in the case of Armillariella mellea, there is observed more conspicuous formation of mycelia clusters, while in the case of Grifola frondosa, the mycelial product has a color close to that of the natural products.
