    Flotation as a tool for indirect DNA extraction from soil

    The method proved to be an efficient alternative to direct extraction protocols where cell lysis is performed in the presence of soil particles. The environmental DNA extracted after flotation had high molecular weight and comparable yield as when using available commercial kits (3.5 mug DNA/g soil), and neither PCR nor restriction enzyme

    In this study we have investigated the use of flotation and filtration, singly and combined, to enhance the separation of plasmid containing liquors from neutralised lysates with very different levels of solids. Filtration of crude neutralised lysates, containing roughly 100 g l−1 solids, through various diatomaceous earth and cellulose precoat materials was invariably accompanied by severe

    Sludge flotation, its causes and control in granular

    Jun 03, 2018 Sludge flotation is a commonly reported and long-standing issue hindering not only the widespread implementation of upflow anaerobic sludge bed (UASB)-type bioreactors in wastewater treatment but also the development of novel anaerobic/anoxic treatment processes such as anammox, partial denitrification, and biological sulfate reduction. This review attempts to address the instability of

    The sequential introduction of KMnO 4 and Fe(II) can realize the moderate pre-oxidation and finally enhance the efficiency of coagulation and flocculation (Ma et al., 2014; Qi et al., 2020; Qi et al., 2016c). Fig. 2 shows the mechanisms of Mn(VII)-Fe(II) pre-treatment for algae removal by Al coagulation. The excessive inactivation of cyanobacterial cells can be prevented by the subsequent

    A scalable process and device for producing a bio molecule, in particular pharmaceutical grade plasmid DNA is described. The process includes the steps of alkaline lysis, neutralization and clarification and can be further extended. For separating the lysate and the precipitate an improved floatation method is disclosed. This method is based on attachment of CO 2 bubbles on the precipitate floe
