Molecular and biochemical characterization of Auricularia nigricans and Muscodor sp. collected in Pueblo Bello, Cesar, Colombia
Synopsis
The exploration of fungal diversity in Cesar, Colombia, represents a strategic priority due to the need to identify bioactive compounds that support the development of a sustainable biotrade in the pharmaceutical, nutraceutical, and agrochemical sectors, as well as to provide resources for the conservation and restoration of ecosystems in the context of climate change. Within this framework, the present study aimed to preliminarily evaluate the biotechnological potential of Auricularia nigricans and Muscodor sp., collected in Pueblo Bello, Cesar, Colombia. The taxonomic characterization of both species was performed using macroscopic, microscopic, and molecular analyses. For A. nigricans, reducing sugars, total carbohydrates, and total phenolic content were quantified to establish an initial biochemical profile. For Muscodor sp., liquid and solid-state fermentations were carried out using mycelium to evaluate extracellular protein concentration and enzymatic activity. Additionally, the bioremediation capacity of the mycelium in aqueous solutions of methylene blue was determined. The results showed that A. nigricans had a high total carbohydrate content and moderate levels of phenolic compounds, suggesting potential applications in the nutraceutical field. Raw enzymatic extracts from Muscodor sp. showed low protein concentration and limited enzymatic activity; however, the mycelium achieved up to 77 % degradation of methylene blue, demonstrating bioremediation potential against dye-type contaminants. This study constitutes the first report on the taxonomic and biochemical characterization of A. nigricans and Muscodor sp. in Cesar, Colombia, providing valuable information for regional bioprospecting and laying the groundwork for future research aimed at identifying metabolites with biotechnological potential.
