摘要

process for the extraction of target dna (more than 300 kb in sizenon culturable contentin an environmental sample, which is ground in a liquid medium.the sample, we get the product is obtained.the rest of the product between the agencies by sedimentation on pillowdensity greater than 1, we get the isolated organismson the surface of the pillow is included in a block are extracted from agarose gel.the dna in the agarose block analysis, we take thethe block in an agarose gel and the electrophoresis is subjected to at least one byalternating field, finally, we get the dna strandthe extracts.
