Floculation bacteria
WebApr 2, 2024 · Bacterial flocculation in a way is advantageous compared to fungal or yeast mediated flocculation, as bacteria have a shorter generation time. However, the major limitation of this method is the production and purification of the bioflocculant. Moreover, for achieving flocculation, a high dosage of the flocculant is required which in turn ... WebMicrobiological flocculation in wastewater by a strain of Bacillus mucilaginosus was examined and the flocculation mechanism was investigated using Coomassie brilliant blue reaction, Anthrone reaction, thin-layer chromatography (TLC), scanning electronic microscope, and infrared spectroscopy.

Web1. The effect of adding pure proteins to bacterial suspensions at different H ion concentrations has been studied. 2. The zone of flocculation of protein-treated bacteria bears a significant relationship to the isoelectric point of the protein used. With the higher concentration of protein, agglutin … WebMar 7, 2024 · Similarly, while all nanoclays induced aggregation of Escherichia coli bacteria, the flocculated bacteria remained alive after aggregation. In contrast, LL-37 alone, i.e. in the absence of nanoclay particles, displays antimicrobial properties through membrane lysis, but does not cause bacterial aggregation in the concentration range investigated.
