RESUMO
A tube culture system was designed for measurement of ethylene evolved by the phytopathogenic bacterium, Pseudomonas solanacearum. The system consisted of 10 glass tubes joined together in series and coated on the inside surface with a dextrose-peptone-casamino acids agar medium. The system provided a large surface for bacterial growth in relation to the volume of air. The system was seeded with a bacterial suspension (7 × 108 cells/ml) drawn through all the tubes by vacuum applied at one end and was then placed in a water bath at 30 C. Air was pumped through the system at 3 ml/min; the outlet was connected directly to the inlet port of a gas sampling loop and ethylene in the sample was determined by gas chromatography.
