This review starts with a brief overview of the molecular biology techniques applied to the bioremediation of soil.

This paper will focus on several aspects of piroplasmosis studied by molecular biology techniques,such as the characterization of genome and chromosomes,molecular pathogenesis,host immune response to infection,gene engineering vaccine and diagnosis by molecular biology techniques.

The application of molecular biology techniques in the classification of microorganisms, which includes DNA (G + C) mol% analysis, nucleic acid hybridization, 16sr RNA sequencing, RFLP and RAPD, amino acid sequencing, protein analysis and Karyotype analysis was reviewed.

Because of the difficulty associated with traditional isolating and culturing bacteria,but the molecular techniques based on culture-independent techniques,extract directly the variable genomic DNA from microbial samples and then analysis the genetic information,by the amplification of polymeric chain reaction(PCR) nucleic acid hybridizerRNA sequence and other methods.

The difference between the bacteria were little and similitude which can t be identified by traditional methods, but the molecular techniques based on molecular biology technologies and concept of bacterial identification made it possible to identify the possible existing bacterial species or content of those bacteria, especial for unable-culturing bacteria in normal conditions.

In this paper, molecular techniques were employed to investigate the spatial and temporal variability of the benthic bacterial communities in Jiaozhou Bay, north China, and the vertical distribution of bacterial and archaeal communities along discrete la.

The article introduces the great success using molecular biology technique in the research of traditional Chinese medicine (TCM).

With the development of molecular biology techniques, the conventional culture-based methods of study on rumen microbial ecosystem is being rapidly replaced by these techniques.

<Abstrcat>This article reviews and summarizes the main molecular biology techniques used in the diagnosis and identification of take-all disease in recent years,and discusses the feasibility of the molecular techniques in the plant disease diagnosis.

Application of molecular biotechnology in detection of bifidobacteria;

This paper gives a review and prospect on the research and application of molecular biotechnology in animal nutrition,including the relationship between nutrition and gene expression and regulation,improving or producing new animal nutrient substance,and developing feed resource by genetic engineering.

The advances of ornamental plants made by molecular biotechnology were reviewed in this paper.

Application of molecular biological techniques in insect phylogeny of the family Tephritidae;

Besides, the gene engineering vaccine obtained from microbes or animal cells is also difficult and expensive to produce,It applying molecular biological techniques to transfer recombined vaccine gene to plant produced botanical vaccine,all above problems would be solved,the people can be immunized by eating p.

Along with the advancement of studying methods, it s more and more extensive application of molecular biological technique to the studies on protozoan research.
