| Popis: | Amino acid liberation by a mutant strain of Anabaena variabilis, ACA 15, was stimulated by increased irradiance, CO2 limitation and by supplying nitrate to N2-fixing cultures of the mutant strain. ACA-resistance in the mutant strain may be attributable to the overproduction of alanine which can inhibit ACA uptake. Nitrite liberation and effects of nitrate on CO2 fixation and of CO2 on nitrogenase activity are altered in the mutant strain. Compared to the parent strain, ACA 15 may be impaired in the ability to adjust its metabolism in response to changes in nitrogen, carbon and energy supply. |
