[Effect of carbohydrate composition of the cytosol of Aspergillus niger conidia on their viability during storage].

It is shown that the rate of sporogenesis, the appearance of low-molecular-weight thiols, and the activation of carbohydrate synthesis in spores adversely affected the viability of Aspergillus niger conidia during storage. Conversely, the prevalence of trehalose over mannitol and the absence of glycerol, erythritol, and glucose in carbohydrate composition facilitated viability of conidia. The data obtained are discussed in regard to the biochemical criteria that may be used to characterize quiescent state of fungi and retaining the viability of the inoculum.
