COSTA, Jefferson Luis da Silva and OLIVEIRA, Virgínia Carla de. Enhancement of soil DNA extraction by the use of a hand held mixer. Braz. J. Microbiol. [online]. 2003, vol.34, n.4, pp. 311-312. ISSN 1678-4405. http://dx.doi.org/10.1590/S1517-83822003000400004.
The efficiency of soil DNA extraction using a bead beater homogenizer (Biospec Products - Germany) was compared to that obtained with a hand held mixer (Moulinex - Brazil). The hand held mixer costs 100 times less and extracted seven times more crude DNA than the bead beater.
