| 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. |
