摘要: A simple and easy protocol for extracting high-quality DNA from different yeast filamentous fungal species is described. This method involves two important steps: first, the disruption of cell walls by mechanical means freezing; second, extraction, isolation, precipitation genomic DNA. The absorbance ratios (A(260)/A(280)) obtained ranged 1.6 to 2.0. main objective this procedure extract pure fungi, including those with high contents proteins, polysaccharides, other complex compounds in their walls. yield quality DNAs were suitable micro/minisatellite primer-polymerase chain reaction (MSP-PCR) fingerprinting as well sequence D1/D2 domain 26S rDNA.
