Flotation cell lysis

Jun 09, 2010 The eDNA extracted after flotation is considered as an indirect method because cell lysis happens only after its separation from the soil matrix. According to the obtained results, this is the first time that an indirect protocol resulted in a similar DNA yield as obtained for direct ones (Table 1)

    May 01, 2016 This method still produces the 2–7% sludge, but enhanced bubble-cell interactions and allowed for cell lysis. Combining harvesting with cell lysis can be desirable to allow for the extraction of lipids . However, there is a significant additional cost associated with using ozone compared to ambient air for the flotation process. 5.4.4
