| influence of carbon and nitrogen sources on the transition from yeast-like cells to chlamydospores in aureobasidium pullulans. | the transition from yeast-like cells to chlamydospores of aureobasidium pullulans can be induced by growing the microorganism on a glucose medium with a limiting nitrogen source and a low buffer capacity. when glucose is used as the carbon source, a concentration higher than 3% (w/v) is required to induce the transition. on the other hand, growth limiting concentrations of the n source (ammonium sulphate) are not required, and higher concentrations actually stimulate the appearance of chlamydosp ... | 1981 | 7196201 |

| influence of ph on the transition from yeast-like cells to chlamydospores in aureobasidium pullulans. | when a. pullulans is grown on a glucose medium with a limiting nitrogen source and low buffer capacity, the yeast-like cells that are originally present undergo a transition to chlamydospores. the initial ph must be around 6 for the transition to take place under optimal conditions. on the above-mentioned medium ph decreases to values below 2 in the first two days; if this decrease is prevented, either by buffering the medium or by repeatedly adjusting the ph to its original value no chlamydospo ... | 1981 | 7198891 |
