The behavior of Aeromonas hydrophila stored at 4 degrees C and 25 degrees C in nutrient-poor filtered sterilized distilled water was investigated. At 4 degrees C, the A. hydrophila population declined below the detection level (0.1 cell mL(-1)) after

The changes in bacterial counts during the storage of a natural mineral water from a French spring were studied. Samples were taken from the spring and the bottling line. Viable cultivable (VC) bacteria were counted on R2A medium. Total counts, viabl

Pectinatus cerevisiiphilusis a strictly-anaerobic, beer-spoilage bacterium. Propionate, acetate and hydrogen sulphide are the major metabolic products of this micro-organism and are responsible for off-flavour of beer. The growth kinetics and the eff

The heat resistance of two strains of spoilage bacteria ( Megasphaera cerevisiae DSM 20461 and Megasphaera cerevisiae DSM 20462) was measured at different temperatures (50–60°C). The values of D 50 are lower at pH 5.2 and 6. At pH 4, the heat resi

Growth curve data which had been fitted by use of the Gompertz and logistic functions have permitted the development of mathematical models to describe the growth of a Pectinatus sp. by several variables, namely, temperature, pH, and ethanol concentr

Fifteen strains from two emergent mineral waters were isolated and tentatively identified with API 20NE and BIOLOG GN systems. These strains were screened for their sensitivities to seven replication-inhibiting antibiotics of the (fluoro)quinolone gr
