Cells immobilized for biosensor applications


This thesis describes several types of whole cell immobilization methods for the ultimate development of a whole-cell biosensor.

Immobilization and patterning of bacterial cells


This web article describes a novel method for attaching bacterial cells to a surface. The cells can be oriented from lying down to standing up on the surface.

Immobilization of bacteria – patents


This page contains an annotated list of patents describing different methods for immobilizing microbial cells and using the formulation for biocatalytic applications.

Living bacteria in silica gels


This page describes an extensive study that examines the viability and physiology of microbial cells entrapped within silica gels. The viability exceeded that of cells free in a liquid suspension.

Bacterial growth of surface pili


Pili are important in bacterial self-immobilization. This article summarizes new knowledge on the structure of bacterial pili.

Bacterial surface appendages


This general microbiology page describes bacterial surface structures relevant to cell self-immobilization.

Protease production by immobilized bacteria


Bacteria entrapped within matrices are useful for the production and catalytic action of enzymes within the cell. This example describes the bacterial production of an alkaline protease.

Industrial application of immobilized cells


This web article contains a large list of references describing application of microbial immobilized cells in biotechnology.

Bacteria attached to basalt


In nature, microbes attach strongly to mineral surfaces. This article describes the constraints on microbial attachment to minerals.

Cell immobilization in hollow fiber membranes


Hollow fiber membranes used for immobilization generally consist of dense and porous surfaces. Cells gain entry through the porous surface.

High efficiency bioconversion surface materials


This page describes a patent for bonding microbes to various surfaces that allow for maximum diffusion of substrates and, hence, high conversion rates.

Immobilized Arthrobacter degrade pentane


This web abstract describes a very stable immobilized cell preparation for the degradation of the solvent pentane.

Biogranulation: Self-immobilized bacteria


This web article reviews cell immobilization with an emphasis on bacterial self-immobilization for remediation of hazardous compounds.
