Filtration is necessary in many engineering field. Polymeric membranes have been used in filtration application for more than a decade. However, some of the contaminants, e.g. radiounuclides and toxic metals, present in soluble form in the waste water and therefore can not be removed by general methods. Although microbes can convert radiounuclides and toxic metals into an insoluble form, successful immobilization of microbes while maintaining their usefulness for any desired application has been elusive. We describe the use of cross-linked polymer hydrogels to encapsulate microbes of water purification genera, such as Alcanivorax, which can digest oil and Pseudomonas fluorescens (P. fluorescens) for purification of heavy metals.
