Factors Affecting Respiration and Germination of Ascospores of the Food Spoilage Mould Byssochlamys nivea
Aerobic respiration studies supported the involvement of acetate ion (0.02M optimum) and a heat-shock of 75°C for 5 min in the germination of ascospores of Byssochlamys nivea. Without these two factors respiration was negligible. An optimum spore concentration of ca 1.2mg/ml for respiration studies...

Summary: | Aerobic respiration studies supported the involvement of acetate ion (0.02M optimum) and a heat-shock of 75°C for 5 min in the germination of ascospores of Byssochlamys nivea. Without these two factors respiration was negligible. An optimum spore concentration of ca 1.2mg/ml for respiration studies was established. None of seven cations tested stimulated aerobic respiration when present at about 10mM concentration. Copper ions at 0.05mM reduced respiration and at 10mM inhibition was complete.
Les études sur la respiration aérobie soutiennent que la germination des ascospores Byssochlamys nivea ne s’effectue pas sans la présence de l’ion acétate (0.02M optimum) et d’un choc thermique de 75 °C pendant 5 minutes. Sans ces deux facteurs, la respiration est négligeable. On a établi qu’il fallait des concentrations optimales de spores d’environ 1.2mg/ml pour effectuer des études sur la respiration. Aucun des sept cations à l’essai n’a stimulé la respiration aérobie lorsqu’ils étaient présents en dose de 10mM. A 0.05mM, les ions de cuivre réduisent la respiration tandis qu’à 10mM, ils l’empêchent complètement. |
