Scanning probe microscope(SPM) is used not only for measuring the micro profiles of surfaces, but also for nano ultraprecise machining and atom manipulation now.

Influence of ica operon transcription on clinical Staphylococcus epidermidis biofilm phenotype;

Studies of biofilm formation of Staphylococcus epidermidis and the genotype and phenotype of ica operon;

ica operon were not affected by glucose on synthesis PIA.

In order to study the effect of the interaction between pur operon and purine repressor PurR on inosinesynthesis, study-type plasmids pYH1206, pYH1618 and pYH1620 were constructed using lacZ as a report gene for a wild-type strain, a low-yield inosine-producing strain and an inosine-producing strain, respectively.

High-level expression of foreign genes via multiple joined operons and a new concept regarding the restricted constant of total amount of plasmid DNA per Escherichia coli cell;

Construction and function analysis of Bac operon mutants of bio-control strain Bacillus subtilis Bs-916

Objective To examine the feasibility of linking operons in tandem to enhance expression of heterologous genes in Escherichia coli and to clarify the potential control mechanism of the total plasmid DNA amount in each host cell.
