Interferon-tau (IFN-tau) is a newly discovered IFN of type I. It was originally found for its role as a pregnancy recognition hormone in ruminant animals such as sheep and cows. Like the other type I IFNs, IFN-tau have the same biological activities including antiviral, antiproliferative and immunomodulatory effects. In order to clearly identify the function of IFN-tau, the coding sequence of IFN-tau was amplified by PCR from IFN-tau cDNA, this fragment digested by EcoR I and BamH I and was inserted into pBV220 to form the recombinant plasmid pBV220/IFN-tau which was then transformed into E.coli BL21. It was found that pBV220/IFN-tau was highly expressed as inclusion body in BL21. Next, the expressed protein was purified on S-100 High Resolution and the purified product was confirmed by amino acid sequence analysis. Moreover, the standard antiviral activity test indicated that the activity of IFN-tau was about 2.09?106IU/ml.

In order to explore reasonable artificial cultivation pattern of Thesium chinense, the biological characteristics and nutrients change in the process of winter dormancy of T. chinense was studied. The phenological period of T. chinense was observed by using fixed-point notation and the starch grains changes were determined dynamically by PAS-vanadium iron hematoxylin staixjing method. Soluble sugar and starch content were measured by anthrone-sulfuric acid method and amylase activity was determined by DN'S method. The results showed that the normal life cycle of T. chinense was two years. T. chinense was growing by seed in the first year, but growing by the root neck bud in the second year. During the process of dormancy, starch and soluble sugar could mutual transformation in different periods. T. chinense had sufficient carbohydrate to maintain growth and also a lot of small molecules to improve their ability to fight against adversity.

Saccharmyces cerevisiae 220 has certain resistance to Pb2+ was found through the test of it's cultured on media containing lead cation. Sacchannyces cerevisiae 220 cultured was put into the media cotaining lead cation and it's biosorp-tion to lead cation was studied. The results show this strain has maximum biosorption ratio (96.6%) to 6mg/L lead cation, biosorption-equilibrilium period is 25-30min, biosorption kinitics equation is q-26.318C/ (1 + 0.437C) . Acetic acid is benefit to de-biosorption, glucose and KH2PO4 can improve biosorption ratio to lead cation.

HIV p24 core protein can induce both cellular and neutralizing antibody responses.HIV-1 CA-virus-like particles(VLPs)vaccines provide a promising approach for the development of an effective vaccination strategy against HIV infection.Rhizosecreion of the recombinant proteins provides a new manufacturing platform that can simplify the extraction and purification procedure.Lycium barbarum L.was transformed by Agrobacterium tumefaciens EHA105 harboring the plant expression vector pCAMBIA1305.2-MA4-CA with a GRP signal peptide and MA4-CA fusion gene.Transgenic hairy roots were induced and cultivated in hydroponic culture.Western blotting indicated that the recombinant CA proteins were present in two forms,a glycosylated monomer(37 kDa)and a dimer(50 kDa)in the roots and hydroponic medium.It appeared from the present immunohistochemical data that the recombinant CA proteins fused with GRP signal peptide were confined to the cytoplasm,cell wall and intercellular space,indicating targeting into the secretory pathway.It demonstrated for the first time the rhizosecretion of HIV-1 recombinant capsid protein in Lycium barbarum L.hairy roots,and may offer a novel method for expressing HIV-1 CA-VLPs vaccines in plants.

The nitrite-reducing activity of aerobic denitrifying bacterial strain N6-1 was studied. It showed that the nitrite-reducing activity reached the highest at 30℃, 120 r/min, pH 8.5 and C/N ratio 12, using CH3COONa and NaNO2 as the sole carbon source and nitrogen source, respectively. When the initial NaNO2 concentration was 2 g/L, NO2--N was reduced completely after 20 hours cultivation with the reducing rate of 20.3 mg/L?h. There would be no effect on its nitrite-reducing activity in the present of 1.5% NaCl or 1% peptone. The cell concentration could reach 1.2?1011 CFU/mL after 24 hours cultivation in 10 L fermentor.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.
