Novel optical sensing method for investigating microbial activity.

Abstract

Studies to investigate preferred optical setups and culture media were carried out. Four optical setups have been examined to measure different niacin concentrations. The configurations tested were as follows: optical probe, extrinsic optical sensor, single decladded fibre optic sensor and double decladded fibre optic sensor. From the experimental results, the most suitable setup was the extrinsic optical sensor.
