OBJECTIVE In order to obtain the antagonistic protein of Bacillus subtilis G87 and definitude its characterization. METHODS Methods of ammonium sulfate precipitating and column chromatography analyzing were used to isolate and purify the protein. RESULTS A purified protein (peak 6-2-1) was obtained which molecular weight was 50.8 kD by SDS-PAGE and(More)

Dynamic Voltage Restorer (DVR), as a device of voltage sag compensation, demands fast transient response, and the disturbance of source voltage is a main impact on control performance. The DVR control strategy based on discrete state space will enhance control bandwidth and stability. However, for the discrete space control system, the number of parameters(More)
Rice sheath blight, which is caused by Rhizoctonia solani, is a devastating disease in many areas of the world where rice is cultivated. The role of polygalacturonase (PG) in the infection process of R. solani was investigated in the present study by cloning and investigating the function of a new PG-encoding gene, which was designated RsPG2. Bioinformatics(More)
OBJECTIVE The study was aimed at understanding the roles of polygalacturonases in the pathogenicity and the interaction between Rhizoctonia solani and rice. METHODS According to the sequences of Rspg1 of R. solani deposited in GenBank, a pair of specific primers was designed. The gene Rspg1 was cloned and expressed using prokaryotic expression tool to(More)
Monte Carlo simulation is a practical and flexible method in power system risk assessment. However, when assessing a large system, the Monte Carlo simulation needs more time for convergence. High accuracy of risk indices demands large-scale sampling calculations and lots of time. This paper proposes a new acceleration algorithm based on scattered sampling(More)
A hybrid sensor kinase termed RetS (regulator of exopolysaccharide and Type III secretion) controls expression of numerous genes in Pseudomonas aeruginosa. To investigate the function of RetS in P. fluorescens FD6, the retS gene was disrupted. Genetic inactivation of retS resulted in enhanced production of 2, 4-diacetylphloroglucinol, pyrrolnitrin, and(More)
