Summary:— Precision instrumentation for measuring ultraweak optical emission from biocultures has been developed. A small-sized unit for detecting optical radiation in the single-photon counting mode based on sensitive photomultiplier tubes (PMTs) with a differential discriminator circuit in each PMT channel has been created. A new four-channel detector system has been designed for detection and processing of electromagnetic oscillations generated by microorganisms in the active and resting phases. The characteristics of the optical emission from Saccharomyces boulardii have been investigated.
