Fungal respiration dynamics influence alkaloid production in Penicillium citrinum, implying alternative pathways support growth.

To explore the relationship between respiratory activity and alkaloid biosynthesis in Penicillium citrinum.
Isolated Penicillium citrinum from ancient permafrost deposits.
Studied respiratory activity during growth with non-fermentable substrates.
Conducted inhibitory analysis of fungal respiration using antimycin A and benzhydroxamic acid.
Maximum respiratory activity coincided with peak alkaloid synthesis and biomass accumulation.
Penicillium citrinum utilized alternative oxidase for growth in the presence of antimycin A.
No alkaloid biosynthesis was observed when glucose was used as a substrate.

A. Yu. Arinbasarova (2025) studied this question.
