| effect of peptone on azotobacter morphology. | pleomorphism in cultures of azotobacter vinelandii was induced by addition of difco peptone to the growth medium. under the conditions of the study, 5% peptone gave rise to transient forms described as "fungoid cells" which were osmotically fragile. after some 48 hr of culture, they became osmotically stable and resumed a more typical morphology. it was shown that the pleomorphism-inducing principle in peptone was glycine. | 1972 | 4591479 |

| interactions of tetrahymena pyriformis, escherichia coli, azotobacter vinelandii, and glucose in a minimal medium. | a study was made of the food web formed from a protozoon, two bacteria, and a glucose minimal medium in chemostat culture. the system was also divided into simpler parts, first by omitting the protozoon to obtain a competition system, and then by omitting one or the other of the bacteria to obtain two food chains. in the competition studies, one bacterium was displaced by the other at all holding times used. in the food chain studies, sustained oscillations of the population densities of predato ... | 1973 | 4632323 |
