Temperature-determined growth and sporulation in the psychrophile Mucor strictus

摘要: The effects of temperature on extension growth, biomass production, sporulation and spore morphology Mucor strictus were investigated together with the ability mycelia to recover from incubation at above-maximum temperatures. Within range −5 25 °C growth over agar was most rapid 20° only slight sporadic 25°. By contrast, maximum dry weight yield occurred 0° although rate production greatest 10–15°. M. even grew frozen media −5°. Sporulation took place all temperatures which supported sporangiospore being a 15°. Previous observations that shape modified by confirmed extended. Mycelia incubated 35–45°, then returned 15°, recovered after lag period extend rates comparable those control cultures held continuously A three-day 45°, but not four days 40°, lethal.
