| Outline of Final Research Achievements |
We tried to show the impact of bacteriophage (phage) to microbiota in shrimp aquaculture using metagenome analysis. Application of metagenome analysis using MiSeq platform to rearing water of shrimp aquaculture pond was studied at the start. The results showed that the analysis could be applied to detect the whole plankton and bacterial population including unculturable ones in the water, which have been remained as a black box. It makes us posible to monitor the dynamics of planktons and bacteria in shrimp aquaculture. To monitor phage dynamics in the environment, we isolated new phages infecting environmental bacteria such as Cytophaga-Flavobacterium group bacteria and deposited the genome sequences. Further we tried to detect phage DNA in the pond water using metagenome analysis, but we obtained a small amount of bacteriophage DNAs and the most of the sequences were remained unknown in reference virus databases. The virus sequences obtained may be of the virus infecting planktons.
