A note on the use of conductimetry in brewery microbiological control

Potentiometric and hybrid electronic tongues for bioprocess monitoring – an overview

“…beer production is carried out using various analytical techniques: spectrophotometry (colorimetric calcium assay), potentiometric titration (total water hardness), hydrometry (alcohol concentration), amperometric sensing (concentration of oxygen), and turbidimetric and pH measurements. 39 Taking into account the composition of the reaction medium, a hybrid electronic tongue based on miniaturized potentiometric and voltammetric sensors (Fig. 1) was developed by our group for homemade beer fermentation monitoring.…”

A medium for the detection of Lancefield Group D cocci in skimmed milk powder by measurement of conductivity changes

“…i Current address: Northern Foods Meat Group, Farnsworth House, Lenton Lane, Nottingham, UK. tance changes produced by lactic acid bacteria have been studied (Evans 1985;Einarsson & Snygg 1986;Yoshida et al 1987); none of the media employed contained selective agents, however, and their effect upon conductivity curves has not been reported.…”

Rapid method for detection of muramic acid and cadaverine as indicators of microbial load on fresh meats

“…The Malthus system has been used for microbial monitoring of brewing liquids (Day, 1983;Evans, 1985), fish and seafoods (Gibson and Hobbs, 1987), and hygiene monitoring (McMurdo and Whyward, 1984).…”
