A simple and inexpensive physical lysis method for DNA and RNA extraction from freshwater microalgae.

ABSTRACT: In this work, a simple and inexpensive physical lysis method using a cordless drill fitted with a plastic pellet pestle and 150 mg of sterile sea sand was established for the extraction of DNA from six strains of freshwater microalgae. This lysis method was also tested for RNA extraction from two microalgal strains. Lysis duration between 15 and 120 s using the cetyltrimethyl ammonium bromide (CTAB) buffer significantly increased the yield of DNA from four microalgalstrains (Monoraphidium griffithii NS16, Scenedesmus sp. NS6, Scenedesmus sp. DPBC1 and Acutodesmus sp. DPBB10) compared to control. It was also found that grinding was not required to obtain DNA from two strains of microalgae (Choricystis sp. NPA14 and Chlamydomonas sp. BM3). The averag
