Effect of salinity on scytonemin yield in endolithic cyanobacteria from the Atacama Desert

Cyanobacteria inhabiting extreme environments constitute a promising source for natural products with biotechnological applications. However, they have not been studied in-depth for this purpose due to the difculties in their isolation and mass culturing. The Atacama Desert sufers one of the highest...

However, they have not been studied in-depth for this purpose due to the difculties in their isolation and mass culturing. The Atacama Desert sufers one of the highest solar irradiances that limits the presence of life on its hyperarid core to endolithic microbial communities supported by cyanobacteria as primary producers. Some of these cyanobacteria are known to produce scytonemin, a UV-screening liposoluble pigment with varied biotechnological applications in cosmetics and other industries. In this work we carried out a strain selection based on growth performance among 8 endolithic cyanobacteria of the genera Chroococcidiopsis, Gloeocapsa and Gloeocapsopsis isolated from non-saline rocks of the Atacama Desert. Then we investigated the infuence of NaCl exposure on scytonemin production yield. Results in the selected strain (Chroococcidiopsis sp. UAM571) showed that rising concentrations of NaCl lead to a growth decrease while triggering a remarkable increase in the scytonemin content, reaching maximum values at 20 g L−1 of NaCl over 50-fold higher scytonemin contents than those obtained without NaCl. Altogether, these fndings point out to cyanobacteria from the Atacama Desert as potentially suitable candidates for pilot-scale cultivation with biotechnological purposes, particularly to obtain scytoneminThe funding was provided by Comunidad de Madrid (LIPEPSTREM project (SI3/PJI/2021-00461), 49/067123.9/20), Universidad Autonoma de Madrid (LIPEPSTREM project (SI3/PJI/2021-00461)), Ministerio de Ciencia e Innovación (Juan de la Cierva-Formación postdoctoral Grant (FJC2020-044126-I)), Agencia Estatal de Investigación (Juan de la Cierva-Formación postdoctoral grant FJC2020-044126-I), European Union NextGenerationEU/PRTR (Juan de la Cierva-Formación postdoctoral Grant (FJC2020-044126-I)), European Regional Development Fund (49/067123.9/20).NatureDepartamento de BiologíaFacultad de Ciencias20242024-04-28research articlehttp://purl.org/coar/resource_type/c_2df8fbb1AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/mswordapplication/pdfhttp://hdl.handle.net/10486/713229https://dx.doi.org/10.1038/s41598-024-60499-4reponame:Biblos-e Archivo.
