The Guardian can reveal that a team of 20 top scientists assembled by Mr Venter,led by the Noble laurate Hamilton Smiith,has already constructed a synthetic chromosome,a feat of virtuoso bio-engineering never previously achieved.Using lab –made chemicals,they have painstakingly stitched together a chromosome that is 381 genes long and contains 580,000 base pairs of genetic code.

家长可以显示一个20人的团队的顶尖科学家通过文特的带领下，高贵的laurate汉密尔顿Smiith，已经建造了一个合成染色体，这一壮举的演奏家生物在以前从未达到使用化学实验室，他们之前在刻意的染色体缝长和包含381基因遗传密码的580，000降到了现在的碱基对。

The effects of several components in the culture medium on Lithospermum erythrorhizon cell growth and secondary metabolite synthesis were studied, as well as structural dynamic model. The two-liquid-phase culture of Lithospermum erythrorhizon was carried out by choosing the proper organic solvent as the second phase. The bioactive carrier for adsorption was prepared and the condition of cell immobilization was determined. We combined the technique of two-liquid-phase culture and immobilization to carry out the culture. We chose the suitable type of reactor, studied its characteristics and results of cell culture using this reactor. The fed-batch operation was also studied on the basis of twoliquid-phase culture and immobilization used in culture in the reactor.
