| Popis: | Two parameters of physiological competence, rate of CO2fixation and intraspecific competitiveness, were determined for one or more atrazine-resistant isolates of the photosynthetic bacteriumRhodobacter sphaeroides. Measured over a 2-h period under optimal conditions, two of the resistant isolates fixed CO2at a greater rate than the atrazine-susceptible, wild-type organism. In a mixed culture study, an atrazine-resistant strain was able to grow and compete successfully with the susceptible, wild-type strain for at least 14 days. |
