| Abstract | ||
| Lichens are one of the most promising sources for bioactive compounds which exhibit different functions including antioxidant, antimicrobial, anti-inflammatory and anticancer effects. However, these beneficial bioactive compounds never make it to the industrial application due to the lichens' extremely slow growth rate which was the drive for in vitro cultivation of the lichen symbionts. In this study, lichen samples were collected from Calligonum polygonoides old shrubs and were identified as Xanthoria parietina following the study of morphological characteristics and performance of spot test (K, C, & KC tests) with reference to the identification keys. Additionally, the lichen internal structure and anatomy were studied in lichen thin sections which clearly illustrated the algal and the fungal layers (the cortex and medulla). Both the photobiont and the mycobiont were isolated through thallus derived culture on BBM and PDA media respectively then were preserved in axenic cultures for further analysis and characterization. The results of this study spot the light on the main associates of Xanthoria parietina paving the way to explore the interaction between them and the secondary metabolites that might be attained from such association. | ||
