(原文来自加拿大Dr. Masanaru Misawa所发表 PLANT TISSUE CULTURE: AN ALTERNATIVE FOR PRODUCTION OF USEFUL METABOLITE)
单词：higher plant 高等植物
food additives 食物添加剂
fermentor发酵罐 fermentation发酵
plant pigment植物色素
shikonin 紫草素
Higher plants contain a variety of substances which are useful medicines, food additives, perfumes, etc. However, decreased plant resources, increases in labour cost and other problems in obtaining these high-value added substances from natural plants have pointed toward the use of plant cell culture for production of the products. Because plant cell culture is not affected by changes in such environmental conditions such as climate or natural depredation, improved production may be available in any place or season.
Therefore, studies on the production of useful metabolite by plant cell culture have been carried out on an increasing scale since the end of the 1950's. The large scale cultivation of tobacco and various vegetable cells was examined in the late 1950's and early 1960's in the U.S., Canada, and Europe. Their results stimulated more recent studies on the industrial application of this technology in many countries.
Since plant cells can be cultivated in various fermentors in a similar way to microbial fermentations, many industrial companies in Japan have tried to apply this technology to commercial production of useful compounds because Japan has a highly developed fermentation technology. At present, two Japanese firms are manufacturing a plant pigment, shikonin, and ginseng cell biomass on a commercial scale and several other products including anti-cancer drugs seem to be close to commercialization., http://www.100md.com
