In this paper we present a new theory to re-examine the immobilization technique of dye doped sol-gel films, define the strength and types of possible bonds between the immobilized molecule and sol-gel glass, and show that the immobilized molecule is

A pH-sensitive colorimetric assay has been established to quantitatively measure glutamate decarboxylase (GAD) activity in bacterial cell extracts using a microplate format. GAD catalyzes the irreversible α-decarboxylation of L-glutamate to γ-aminobutyrate. The assay is based on the color change of

High concentrations of H(2)S in groundwater are commonly removed using Biological Trickling Filter (BTF) that contains high numbers of biofilm immobilized sulfur oxidizing bacteria (mainly Thiobacillus thiooxidans). BTF performance requires continuous monitoring of these bacteria at several sampling points. The
