Despite the presence of cold-resistance mechanism in bacteria, many pollution problems have been reported to occur in the rivers, lakes, ground waters, and process effluents of the industrialized world especially in the cold season. The production of exo-biopolymer by psychrotrophic bacteria and their probable role in the environment, especially in terms of heavy metal adsorption is observed. This book contains data of extensive experimental work on cold induced biopolymer production and sorption using FE-SEM, RPHPLC, HPAEC-PAD, DSC and WXRD. Adsorption isotherms and kinetic modeling were done...
Despite the presence of cold-resistance mechanism in bacteria, many pollution problems have been reported to occur in the rivers, lakes, ground waters, and process effluents of the industrialized world especially in the cold season. The production of exo-biopolymer by psychrotrophic bacteria and their probable role in the environment, especially in terms of heavy metal adsorption is observed. This book contains data of extensive experimental work on cold induced biopolymer production and sorption using FE-SEM, RPHPLC, HPAEC-PAD, DSC and WXRD. Adsorption isotherms and kinetic modeling were done to predict the types of sorption which were further confirmed by EDX, FTIR and chemical modification. Many biosorption studies were conducted worldwide. But no effort of establishing a model for choosing better biosorbent was observed. This is the first time; a totally new model for the field of environmental biotechnology is established in this book. It can be extremely useful to screen a better biosorbent for one or several particular metals in a particular environment. From this study we can also see a new bacterium which can produce a multifunctional aminosugar and their molecular basis.
