Sensor characterised in that it is principally constituted, on the one hand, by at least one probe (2, 2') each essentially consisting of an optical fibre (13) whose end is covered with a translucent membrane supporting the culture of immobilised light-emitting (luminescent) bacteria, the said probe or probes (2, 2') being able to be supplied, either with fluid to be monitored or with regeneration fluid, via various fluid circulation circuits (3, 4), selected by means of actuatable valves (5, 6), and, on the other hand, by devices (7, 8, 9, 10) for regulating certain physical and/or chemical characteristics of the fluid to be monitored, these devices being placed upstream of the probe or probes (2, 2'), and, finally, by a device (11, 12) for processing and analysing the signal or signals supplied by the probe or probes (2, 2'). <IMAGE>
