Use of Tetra-ammonium Tetrakis(4-Sulphonato)Phenyl Porphyrin forPseudomonasandBacillusCell Imaging

[摘要] The use of tetraammonium tetrakis(4-sulphonato)phenyl porphyrin (TPPS), a water-soluble anionic compound, as a stain to analyse bacterial cells using fluorescent microscopy was investigated. TPPS was effectively used to analyse two different bacteria:Pseudomonas aeruginosaandBacillus cereus. The variation in brightness with varying concentrations of TPPS was studied. The patterns of variations for these bacteria were found to be the same, but with consistently higher brightness forBacillus cereus.
