The article reveals the problems of aesthetic education of young people as a necessary condition for the cultural development of the individual in the modern conditions of the information society. Aesthetic education should contribute to the formation of a creatively active personality. The basis of aesthetic education of young people in the modern conditions of the information society is the core of artistic culture - art as a unique form of public consciousness that contributes to the spiritual development and improvement of the inner world of a person. The main tasks of aesthetic education are highlighted. It is focused on the formation of aesthetic consciousness and aesthetic behavior of the individual. The formation of true aesthetic and spiritual values of students is impossible without a deep awareness of the national foundations of culture, which combines science (including technology), education, art, morality, way of life and worldview, and most importantly its information component - information culture. The effectiveness of aesthetic education of students largely depends on the skillful use of various methods and means by teachers. Aesthetic education of students involves a qualitative change in the level of their aesthetic culture in the modern conditions of the information society. In the era of information and computer technologies, the main Institute for aesthetic education of young people, as a necessary condition for the cultural development of the individual, is mass media. Television stands out especially because it has several information series (audio and video sequence), multiplied by the efficiency of providing information that increases several times compared to paper media, which allows you to report directly during the event.

For the efficient production of a new exo-polysaccharide from Ganoderma lucidum ASI 7004, the optimum conditions and methods in submerged cultivation were investigated with an airlift fermenter system. The optimum aeration rate was 2.5 Wm at the initial pH 5.0 and 28$^{\circ}C$. The increase of dissolved oxygen concentration by pure oxygen supply during cultivation did not improved the exo-polysaccaride production and the mycelial growth. The maximum exo-polysaccharide production and the mycelial growth under the optimum culture condition were obtained in media of glucose 60g/L, yeast extract 6g/L, (NH4)2HPO4 1g/L and KH2PO4 0.5g/L. Under these optimum medium and culture conditions, about 7.15g/L of exo-polysaccharide and 13.9g/L of mycelial growth were producted, respectively.

A dominant planktonic bloom-forming species, Mallomonas elongata was isolated from a small shallow eutrophic pond. The growth characteristics of this species on variable silicate concentrations and light intensities were investigated in laboratory unialgal cultures. In culture condition of $15^{\circ}C$, the maximum population growth and the highest growth rate of M. elongata occurred at a light intensity of $80\;{\mu}mol\;m^{-2}s^{-1}$, and in culture condition of $18^{\circ}C$, it exhibited the maximum population growth and the highest growth rates at a light intensity of $50\;{\mu}mol\;m^{-2}s^{-1}$. Silicate concentration had no effect on the population growth and growth rate of M. elongata.

Continuous culture was carried out with a recombinant Escherichia coli W3110/pCR185, which encodes trp-operon enzymes when the temperature is shifted from $37^{circ}C\;t;42^{\circ}C$. Under derepressed condition of $42^{\circ}C$. plasmlid stability and gene expression were analysed as function of the dilution rate. The stability of plasmid increased with the dilution rate, but maximal levels of gene expression (tryptophan concentration) and plasmid DNA content were obtained at the lowest dilution rate, $0.075\;hr^{-1}$. The plasmid instability, observed at low dilution rates, could be explained by the unbalanced biosynthetic state of the recombinant cell harboring a high copy number of plasmid.

The result of isolated and selected to the strain having the emulsifying activity from soil's strain the strain was identified as Candida genus. The strain was investigated with culture condition at pH culture temperature, flow rate of air, strring rate etc., and physicochemical properties of the biosurfactant were examined. The optimum composition of medium for a strain cultivation were obtained as follow : glucose ; 100g/L, yeast extract ; 10g/L, urea ; 1.0g/L, KH$_{2}$PO$_{4}$ ; 50mg/L, MgSO$_{4}$ ; 500mg/L, and the op condition of cultivation was as follow : pH ; 3.0, temperatlue ; 24$\circ $C, strring rate ; 40rpm. The maximum yield of biosurfactant was obtained by pH ; 3.0-3.5, and temperature ; 25$\circ $C. The degree of emulsification of syntesized biosurfactant was increased clearly by increasing concentration of biosurfactant and it's stability was maintained for a long time. The surface tension of biosurfactant was varied with pH, especially it was showed that the surface tension was high at acidic pH.

The present study has been carried out to investigate the optimal condition on the blastogenesis of guinea pig lymphocytes. A microculture system in conjunction with a semiautomatic multiple sample harvester(SAMSH) was used to study the in vito optimal condition of guinea pig lymphocytes. Data were presented to show many variables that are Involved in studying the responses of guinea pig lymphocyte in a microculture system to the stimulation of Concanavalin A(Con A) and lipopolysaccharide (LPS). Analysis indicated that the conditions for optimal Con A as measured by incorporation of $^3H$-TdR include : (1) use of RPMI-1640 as culture medium, (2) use of $6{\mu}g$ of Con A, per culture, (3) use of $1{\times}10^6$ cells per culture. Conditions for optimal stimulation with LPS mitogen were similar to those used for Con A.

It was explained in detail that the present condition of herb culture in Japanese agriculture and the requirement of crude drugs of good and regulqr very hard hit by the market conditionof crude drugs taking ginseng (Panax ginseng C.A.Meyer) and Coptis Rhizome (Coptis japon-ica Makino) as examples. It is not too mach to say that the market is now under the control ofcrude drugs imported from China. The main current of herb culture in Japan will be the con-tract agriculture that the seedlings of good and regular quality are received and are cultivateduntil the enough time, and the farm products are directly handed to the medicinal company fol-lowing the example of zedoary (Curcuma zedoaria Roscoe) .

The effect of media composition and culture condition on mycelial growth and cordycepin (3'-deoxyadenosine) production was determined using Cordyceps spp. Among the strains of C. militaris and C. sinensis tested, C. militaris KCTC 6862, C. militaris DGUM 32003 and C. militaris KCTC 16932 were excellent for the production of cordycepin. The optimal temperature and pH for production of cordycepin were $24^{\circ}C$ and pH ranged from 6.0 to 10, respectively. Among various sources of carbon and nitrogen tested, glucose and tryptone were very excellent for the production of cordycepin, respectively. After 5days cultivation with 1% of tryptone with nitrogen source, 39mg/l of cordycepin was produced. However, addition of phosphorus sources reduced the production of cordycepin.

This study was carried out to obtain basic data on mycelial growth characteristics for an artificial cultivation of Grifola frondosa. Ten strains of G. frondosa were collected from Korea, China and Japan and investigated its optimal culture condition. Among four kinds of mushroom culture media, PDA medium was selected as the suitable culture medium. The optimal conditions for the mycelial growth of G. frondosa in PDA medium were $25^{\circ}C$ and $4{\sim}5$ of pH, respectively. The carbon and nitrogen sources for the optimum mycelial growth were fructose and peptone, respectively, and the highest mycelial growth was observed when the C/N ratio was $10{\sim}20$.

Allium wakegi was cultured shoot tip in the condition of light culture. The Allium wakegi added plant growth regulator was observed of plant regeneration and bulblet formation. Callus Induction and growing rate was the best of 78％ when added alone 2,4-D 0.5mg/L. In the formation of shoot, its regeneration rate was 96％ when added BA 0.5mg/L in the light culture condition. When BA 0.5mg/L and NAA 0.5mg/L mixed and BA 0.5 mg/L and NAA 1.0mg/L mixed, the rates were 99％ and 97％ respectively, and these conditions were suitable for forming shoot. In the formation of roots, when added NAA 2.0mg/L in the light culture condition, the regeneration rate was 90.6 ％ and the roots were abnormal. When added NAA 1.0mg/L, the rate was 82 ％ and the highest. In the formation of bulbs, when BA 05mg/L and NAA 1.0mg/L mixed, the root generantion and its size in the bulbs was the best compare to other treatment experiments.
