    摘要: In accordance with the present invention, isolated nucleic acid encoding a host cell protein that regulates Tat transactivation has been discovered. The protein is the first discovered constituent of the TAK/TEFb complex which associates with the HIV Tat, via divalent cation metals, and is necessary for the binding of Tat to TAR RNA. This protein, cyclin T1, is an 87 kDa cyclin partner for the PITALRE kinase. It is further discovered that Tat must interact with TAK in order to bind to TAR RNA with affinity and with the appropriate sequence specificity that is observed in vivo. In accordance with another aspect of the invention, formulations useful for modulation of Tat transactivation have been developed. In addition, assays have been developed for the identification of compounds useful to modulate the above-described processes.

    摘要: This invention belongs to the field of biochemical engineering and relates to a method of cyclic utilization of water during separation of succinic acid made by fermentation. This invention uses water from separation process for aerobic growth of E.coli AFP111 and production of succinic acid by anaerobic fermentation, obtaining final succinic acid concentration of 55 g/L and yield of 91.6%. Compared with results of fermentation using culture medium prepared from tap water, succinic acid concentration and productivity increased by 8.5% and 8.46%, respectively. An outstanding advantage of this invention is recovery and utilization of evaporated water during separation of succinic acid, realizing cyclic use of water during industrial production of succinic acid, which is an environment-friendly process. Also, as evaporated water generated during separation of succinic acid contains small amount of organic acids such as acetic acid and formic acid, if this water is used for aerobic growth of thalli, the small amount of organic acids contained therein can be used as gluconeogenesis carbon source, improving activity of some key enzymes in cell and favoring succinic acid production by anaerobic fermentation of thalli.

    摘要: The present invention discloses a method of improving the fermentation yield of polyunsaturated fatty acids, in which Schizochytrium limacinum is used as production strain to produce polyunsaturated fatty acids (PUFA), and glycine betaine or trehalose is added to the fermentation medium. In the present invention, after Schizochytrium limacinum fermentation system is treated with exogenous glycine betaine, the yield of PUFA produced by fermentation with Schizochytrium limacinum can be greatly improved. The present invention significantly improves the yield of PUFA produced by microorganism, reduces the cost without harming the environment, and saves manpower and material resources by simple and effective regulation of fermentation, and thus the method is simple, convenient and cost-effective.
