Strain 031057 was isolated from sea sand, collected from the South Sea. It was a bacterium with endospore, not movable, belonged to G+.Relative inhibition concentration of the bioactivity produced by 031057 was 100 mg/mL corresponding to hygromycin B.

After thermal induction, no specific recombinant protein band in SDS-PAGE was found, but G-CSF activity was detectable. Therefore, a new recombinant plasmid pBVHG2 expressing hG-CSF hybrid protein with additional 8 amino acids which could be cut off specifically with the help of mucosal enterokinase at the N terminus of hG-CSF was constructed.

含此质粒菌株虽然表达菌体裂解后可测得明显的生物学活性，但SDS-PAGE仍未见特异表达产物带；因此，再应用相同方法，在hG-CSF cDNA突变体5′端增加24核苷酸对的FLAG肽编码序列，构建了hG-CSF杂交蛋白（hG-CSF天然蛋白N末端增加8aa的FLAG肽，后者可由肠激肽酶切除）的表达质粒pBVHG2。

According to the estimation of biomass in Nosiheptide fermentation process, the secondary variables are selected according to the implicit function existence theorem, and then a soft sensor model of biomass is developed by using the IBPNN. The testing result shows the effectiveness of the presented approach.

The culture of Micrococcus aureus in lag phase and decline phase are more sensitive to TFP than that of in logarithmic phase and stable phase.

抗菌蛋白对金黄色微球菌表现出杀菌作用，但无溶菌现象；在金黄色微球菌的四个生长阶段中，延滞期与衰亡期菌体对抗菌蛋白的敏感性强于对数期及稳定期。

Based on that the dielectric permittivity of cell suspensions is monotonic function of the measuring frequency and cell concentration at radio-frequencies,a new method for detecting cell concentrations on-line and in-situ is proposed .

利用发酵液在无线电频率范围内的电容率是测量频率与菌体浓度的函数，提出了一种实时在线检测发酵过程菌体浓度的新方法，设计了检测传感器和自动检测系统，并且实验验证了该检测方法及检测系统的可行

In 50L fermentor, the metabolic characteristics of carbohydrate, DO, NH〓-N and dissolved phosphorus, cell growth and CTC biosynthesis were analyzed intensively. It was put forward that the cell growth on the initial stage of fermentation must be controlled properly in order to achieve the goal of fermentation process optimization.

研究了50升发酵罐中CTC发酵过程的糖、氧、氮和磷的代谢特性以及菌体生长和金霉素合成的规律，并提出通过在发酵前期控制菌体生长的方法来达到过程调控和优化的目的。
