Additional file 6 of Production of cadmium sulfide quantum dots by the lithobiontic Antarctic strain Pedobacter sp. UYP1 and their application as photosensitizer in solar cells

Additional file 6: Dataset S6. H2S(g) liberation assay. White filter paper was moistened with a 0.1 M lead acetate solution, air-dried and attached to the lid of tubes with different conditions. H2S(g) liberation was therefore assessed according to the lead acetate method [46]. (a) Negative control (R2A medium) with or without 1 mM cysteine and Pedobacter sp. UYP1 strain grown in R2A medium, with or without 1 mM cysteine. (b) Relative intensity values obtained from the pixel intensity analysis of the images in a.
