Basidiomycetes white-rot fungi which can secrete several extracellular enzymes, in which lignin peroxidase plays a dominant role in lignin degradation. In the present study, some characters of the amino acid sequence of P. chrysosporium lignin peroxidase were predicted and analysed with the tools of bioinformatics. These results showed that the protein was composed of 19 kinds of amino acid; the theoretical...
In the present study we reported the feasibility of extracellular biopolymer(PF-9) produced by Pseudomonas fluorescence C-9 as an alternative biosorbent to remove Ni(II) metallic ions from environmental and industrial wastewater. The ability of PF-9 to remove the Ni(II) ions was investigated by using batch biosorption procedure. The effects such as pH, dosage of biosorbent, Ni(II) initial concentration...
The study on molecular structure of Fusarium proliferatum clinically isolated can provide the basis for accurate diagnosis and treatment of F. proliferatum infection. The rDNA ITS gene of 6 strains that had been identified as Fusarium proliferatum based on morphological were cloned and sequenced. The molecule phylogenetic tree was constructed based on rDNA ITS sequences, and the 6 genus were divided...
To investigate the phytotoxicity and tolerance responses of radish (Raphanus sativus L.) to Lead (Pb), plants of two genotypes were exposed to various concentrations of Pb (0, 100, 400 and 800 mg L-1) for up to 8 days by hydroponics culture. The plant growth was inhibited under Pb stress, with the decrease of root length, fresh and dry weights. Excess Pb induced MDA contents increasing significantly...
In order to understand the role of monocytes and macrophages (MPhi) in the pathogenesis of SARS, we detect pathological changes, cell apoptosis and expression levels of CD68, Mac387, CD25, ACE2 and S protein in the specimens of lungs, spleen and lymph nodes. Plenty of infiltrating MPhi could be seen in a number of tissues including the alveolus cavity, the lymphatic sinus in lymph nodes and the splenic...
Piezoelectric biosensor combines the sensitivity of piezoelectric sensor and specificity of biological reaction. Compared with traditional biochemical assay, it has the features of simple structure, having no use of label and fast detection speed. In recent years, piezoelectric biosensor has been applied in the area of clinical analysis, biological technology and food sanitary detection. In this paper,...
