The biophotontech is widely used and we expect to apply this advanced technology to examine the cosmetics and cosmetic ma.

Bioluminescence technique study of telomerase activity in the testis of SD rats and its significance;

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.
