Respiration and Substrate Utilization by Marine Fungi: Their Ecological Role in an Upwelling Ecosystem.

ABSTRACT: Marine fungi are relevant ecological components of microbial communities and play crucial roles in the degradation of organic matter and the cycling of nutrients in oceanic ecosystems. However, their metabolic adaptations to dynamic, nutrient-rich coastal upwelling environments remain scarcely known. The aim of our research is to contribute to the understanding of the ecological and biogeochemical roles of marine fungi in upwelling systems. To this end, we investigated the metabolic responses of three fungal strains (Sarocladium sp., Penicillium sp., and Fusarium sp.) isolated from the coastal upwelling off central-south Chile. The growth and respiration rates of these marine fungi were comprehensively evaluated using a diverse array of substrates, including glucose, c
