Abstract

The type of sporulation medium and time of incubation had an effect on spore viability and citric acid production by mycelia grown from Aspergillus niger spores. Shu & Johnson agar (SJA) and potato dextrose agar gave higher citric acid titres than malt-extract agar. SJA also gave better germinability than the other media. Viability increased with time of incubation, but higher production of citric acid was achieved with spores incubated for less than 7 days.

摘要

在影响黑曲霉孢子形成的产孢培养基类型和培养时间方面，孢子形成的培养基类型和培养时间对菌丝体的孢子活力和柠檬酸产量有影响。Shu 和 Johnson 琼脂（SJA）和土豆葡萄糖琼脂比麦芽提取物琼脂产生更高的柠檬酸产量。SJA 的发芽率也比其他培养基好。活力随着培养时间的增加而增加，但培养时间少于 7 天的孢子可以实现更高的柠檬酸产量。
