Strain UHM-5, a pSym Exo derivative of the aluminum-tolerant Rhizobium leguminosarum bv. phaseoli strain CIAT899, was equally tolerant of aluminum (Al) as the parental culture. Dialyzed culture supernatants of the wild-type cells grown in YEM broth (10 cells ml) contained 185 mug of glucose equivalents ml whereas UHM-5 culture supernatants yielded 2 mug of glucose ml. The Exo derivative and the parental strain gave essentially similar growth in medium containing from 0 to 300 muM Al, indicating… CONTINUE READING
