✦ Synopsis

Bacterial Bioflocculant for Multifunctional Features highlights research findings on the production and characterization of self-assembling bioflocculant from bacterial consortium (encompassing Bacillus subtilis, Enterococcus faecalis and Proteus mirabilis). The book describes the various high-throughput techniques for characterization of wastewater at microbiological and molecular level.  Sections cover pharmaceutical compounds, macromolecular compounds and other contaminants, the biotoxicity exhibited cellular and nuclear abnormalities in the zebra fish, and high-throughput techniques used for evaluating the flocculating efficiency of the bacterial bioflocculant to remove the contaminants in different other applications.

Bacterial Bioflocculant for Multifunctional Features will help users undertake further advanced research in bacterial bioflocculant for bioremediation technology and environmental prospectives. In addition, it will also inspire readers to understand bioflocculation and its functions.
