A novel microbial BOD biosensor developed by the immobilization of P. Syringae in micro-cellular polymers. Kara, S., Keskinler, B., & Erhan, E. JOURNAL OF CHEMICAL TECHNOLOGY AND BIOTECHNOLOGY, 84(4):511-518, 2009. abstract bibtex BACKGROUND: A biochemical oxygen demand (BOD) sensor, based on an
immobilized Pseudomonas syringae in highly porous micro-cellular
polymer (MCP) in combination with a dissolved oxygen electrode, has
been developed for the analysis of biodegradable organic compounds in
aqueous samples. Microorganisms were immobilized in a molded MCP disk
and a wastewater sample was injected into the biocomposite disk by a
flow injection system. Dissolved oxygen (DO) changes as a measure of
soluble BOD was read with a DO probe placed into a flow cell carrying
biocatalytically activated disk.
RESULTS: Optimal response of the MCP BOD sensor was obtained at pH 6.8
and 25 degrees C with a typical response time of 3-5 min for a 2 mm
thick molded polymeric disk. The sensor showed detection linearity over
the range 5-100 mg L-1 BOD5 (r(2) > 0.99) at a flow rate of 0.6 mL
min(-1). The repeatability and reproducibility of the sensor response
were found to be 3.08% and 7.77%, respectively. BOD values produced
with this biosensor for various municipal and industrial wastewaters
correlated well with those determined by the conventional 5-day BOD
test.
CONCLUSION: This new biosensor was different from present amperometric
BOD biosensor configurations in which the biocatalyst
(microbial/enzymatic) is placed between cellulose and Teflon membranes
installed on a DO probe. The use of a molded MCP disk coniainng
microbial activity offers better stability and lifetime for commercial
use in environmental monitoring. (c) 2008 Society of Chemical Industry
