    Effects of SSF-126, a novel alkoxyiminoacetamide blasticide, on mycelial growth and oxygen consumption of Pyricularia oryzae (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Plant pathology 44 (1995), S. 0

    Notizen: SSF-126, (E)-2-methoxyimino-N-methyl-2- (2-phenoxyphenyl)acetamide, inhibited mycelial growth (IC50 7·7 μM) of Pyricularia oryzae. The inhibited mycelium, which was incubated for 30 h in the presence of SSF-126, grew vigorously after transfer to a fungicide-free medium, indicating that SSF-126 is a fungistatic compound. SSF-126 strongly inhibited oxygen consumption by P. oryzae at low concentrations (IC50 0·8 μM). However, the initial inhibition of oxygen consumption was followed by normal mycelial respiration that was insensitive to SSF-126. These results suggest that SSF-126 has a new type of antifungal action.

    Rapid detection and counting of single bacteria in a wide field using a photon-counting TV camera (1991)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 83 (1991), S. 0 
    Details
    ISSN: 1574-6968

    Thema: Biologie
    Notizen: Abstract: Using Escherichia coli as a model bacterium, we tested a photon-counting method for enumeration of bacteria. This method is based on the principle that microscopic sized luminous particles in a wide field can be directly detected and counted using a photon-counting TV camera without the use of a microscope. E. coli cells were labeled with peroxidase and luminescence induced by adding a luminol-based reaction mixture. The number of luminous spots in the TV images was in good agreement with the number of bacterial colonies grown from labeled cells. The results show that our method provides a rapid and easy microbial counting system for such purposes as clinical diagnosis, microbial analysis in food, and environmental assessment.

    A novel method for detection and counting of single bacteria in a wide field using an ultra-high-sensitivity TV camera without a microscope (1991)

    Notizen: Abstract: We describe a novel method for enumeration of bacteria, based on the principle that small, light emitting particles on a flat surface can be easily and rapidly detected and counted using an ultra-high-sensitivity TV camera. To test this method, we obtained TV images of individual cells of a luminous bacterium on a membrane filter without the use of a microscope. The positions of the luminous points in the TV images were almost the same as the positions of the bacterial colonies after growth. Our results show that the single cells can be efficiently detected and counted by our method if they emit light or can be stimulated to emit light.
